WEBVTT - How Web Analytics Work

0:00:04.120 --> 0:00:07.160
<v Speaker 1>Get in touch with technology with tech Stuff from how

0:00:07.200 --> 0:00:13.760
<v Speaker 1>stuff works dot com. Hey there, and welcome to tech Stuff.

0:00:13.760 --> 0:00:16.320
<v Speaker 1>I'm your host, Jonathan Strickland. I'm an executive producer and

0:00:16.360 --> 0:00:21.000
<v Speaker 1>how Stuff Works and I love all things tech and

0:00:21.160 --> 0:00:24.960
<v Speaker 1>tech stuff. Listener Wrath wanted me to do a show

0:00:25.440 --> 0:00:31.240
<v Speaker 1>about web analytics, and specifically about web analytics and your

0:00:31.320 --> 0:00:35.320
<v Speaker 1>personal data. Your data being the general you out there,

0:00:35.360 --> 0:00:38.360
<v Speaker 1>like how much of your personal data gets wrapped up

0:00:38.479 --> 0:00:42.280
<v Speaker 1>in web analytics. This is actually a really big topic,

0:00:42.320 --> 0:00:44.199
<v Speaker 1>so I'm going to take a couple of episodes to

0:00:44.240 --> 0:00:46.559
<v Speaker 1>cover it, and this first one we're gonna talk just

0:00:46.640 --> 0:00:50.599
<v Speaker 1>about web analytics, what they are, why they are necessary

0:00:50.680 --> 0:00:53.640
<v Speaker 1>in the web that we know and love today, And

0:00:53.680 --> 0:00:56.480
<v Speaker 1>in the next episode, I'll go more into detail about

0:00:56.960 --> 0:01:00.880
<v Speaker 1>the sort of data that they can gather are about you.

0:01:01.120 --> 0:01:03.920
<v Speaker 1>So there's a lot to consider. Some of it gets

0:01:03.920 --> 0:01:06.240
<v Speaker 1>a little technical, but we're gonna go light on that.

0:01:06.360 --> 0:01:09.760
<v Speaker 1>Will will explain what the technical aspects are, but we

0:01:09.800 --> 0:01:12.720
<v Speaker 1>won't get too bogged down because it would involve talking

0:01:12.760 --> 0:01:15.640
<v Speaker 1>about lines of code and that would get pretty awkward

0:01:15.680 --> 0:01:18.560
<v Speaker 1>without visual aids. Uh. A lot of this can get

0:01:18.560 --> 0:01:24.560
<v Speaker 1>a little scary because web analytics are valuable, and they

0:01:24.760 --> 0:01:27.400
<v Speaker 1>really do chip away at your privacy. But let's start

0:01:27.400 --> 0:01:31.880
<v Speaker 1>from the top. What are web analytics. Well, at their

0:01:31.920 --> 0:01:35.800
<v Speaker 1>most basic level, web analytics would be a collection of

0:01:35.840 --> 0:01:41.520
<v Speaker 1>tools and strategies that allow people to collect and measure

0:01:42.319 --> 0:01:48.560
<v Speaker 1>Internet data, specifically user generated Internet data, typically as a

0:01:48.560 --> 0:01:53.960
<v Speaker 1>way to understand user behavior, and that is done so

0:01:54.040 --> 0:02:00.400
<v Speaker 1>that the website owner can optimize experiences and leverage that

0:02:01.120 --> 0:02:04.600
<v Speaker 1>user behavior in some way that ultimately corresponds to making money.

0:02:04.680 --> 0:02:08.080
<v Speaker 1>If I'm gonna be and entirely honest about this, it's

0:02:08.080 --> 0:02:11.200
<v Speaker 1>all about figuring out how to make the most compelling

0:02:11.240 --> 0:02:15.280
<v Speaker 1>experience to maximize the most return on an investment, that

0:02:15.400 --> 0:02:18.880
<v Speaker 1>investment being the time, money, and effort you put in

0:02:18.919 --> 0:02:22.560
<v Speaker 1>to creating a website. So this is not necessarily the

0:02:22.560 --> 0:02:26.920
<v Speaker 1>owner of the website and might be the advertising company

0:02:26.960 --> 0:02:31.720
<v Speaker 1>that brokers deals with various companies to place ads on websites.

0:02:32.240 --> 0:02:36.160
<v Speaker 1>But somewhere there's a person who's analyzing, or more likely

0:02:36.200 --> 0:02:39.120
<v Speaker 1>a system that's analyzing this information in an effort to

0:02:39.240 --> 0:02:42.160
<v Speaker 1>maximize that return. Now, in many ways, this is kind

0:02:42.160 --> 0:02:45.960
<v Speaker 1>of following a long tradition that's been effective in meat space,

0:02:46.040 --> 0:02:48.200
<v Speaker 1>you know, in the real world. If you go to

0:02:48.320 --> 0:02:52.160
<v Speaker 1>a brick and mortar shop regularly, you've probably noticed that

0:02:52.240 --> 0:02:56.720
<v Speaker 1>sometimes stuff gets moved around the shop might reorganize. Most

0:02:56.760 --> 0:02:59.560
<v Speaker 1>of the time, this is because the shop owners are

0:02:59.600 --> 0:03:02.919
<v Speaker 1>trying to change things up in order to encourage more purchases.

0:03:03.480 --> 0:03:06.840
<v Speaker 1>So grocery stores are a great example of this. The

0:03:07.040 --> 0:03:11.160
<v Speaker 1>layout of your basic supermarket in the United States tends

0:03:11.200 --> 0:03:14.400
<v Speaker 1>to be fairly standard. No matter what type of store

0:03:14.440 --> 0:03:17.000
<v Speaker 1>you go to. It could be a Kroger or a Wegman's,

0:03:17.080 --> 0:03:19.200
<v Speaker 1>or a Whole Foods or a Piggy Wiggly or a

0:03:19.200 --> 0:03:22.600
<v Speaker 1>safe Way or whatever, they all tend to have a

0:03:22.680 --> 0:03:26.880
<v Speaker 1>similar layout. So you walk in, you probably will see

0:03:27.280 --> 0:03:31.280
<v Speaker 1>flowers very frequently grocery stores and supermarkets. While flowers near

0:03:31.320 --> 0:03:35.080
<v Speaker 1>the entrance, this sets a pleasant scene. It reminds people

0:03:35.240 --> 0:03:40.120
<v Speaker 1>of freshness, bright colors. Behind that you typically find the

0:03:40.120 --> 0:03:44.360
<v Speaker 1>produce that contains fruits and vegetables and vibrant colors, and

0:03:44.480 --> 0:03:46.840
<v Speaker 1>that again engages your senses. It makes you think of

0:03:46.880 --> 0:03:50.080
<v Speaker 1>the food is being fresh. Over in the bakery section,

0:03:50.240 --> 0:03:53.640
<v Speaker 1>you've got an area which typically creates a lot of

0:03:53.800 --> 0:03:58.160
<v Speaker 1>very pleasing smells that will often make you feel hungry.

0:03:58.200 --> 0:04:00.760
<v Speaker 1>That means that when you're hung greet you you tend

0:04:00.840 --> 0:04:03.080
<v Speaker 1>to buy more than what you need. Right. So, if

0:04:03.080 --> 0:04:05.080
<v Speaker 1>you've ever had this experience, you know what I'm talking about.

0:04:05.080 --> 0:04:07.040
<v Speaker 1>You go into the grocery store, you've got a list,

0:04:07.240 --> 0:04:09.320
<v Speaker 1>You've got three things on your list, You walk by

0:04:09.360 --> 0:04:11.960
<v Speaker 1>that bakery. Next thing you know, you're in the checkoutline

0:04:12.000 --> 0:04:14.360
<v Speaker 1>with eight things in your cart. Instad of the three

0:04:14.400 --> 0:04:17.200
<v Speaker 1>things that you had planned. Happens to the best of us,

0:04:17.279 --> 0:04:20.000
<v Speaker 1>and it happens by design, by the design of the

0:04:20.040 --> 0:04:22.920
<v Speaker 1>grocery stores. They people figure this out. They said, well,

0:04:23.040 --> 0:04:26.000
<v Speaker 1>let's put this here because we'll make more sales. This

0:04:26.040 --> 0:04:27.800
<v Speaker 1>has all been studied, by the way. I'm not just

0:04:27.880 --> 0:04:30.920
<v Speaker 1>spit balling here. This is why grocery stores are laid

0:04:30.960 --> 0:04:33.960
<v Speaker 1>out the way they are. Uh. You also see this

0:04:34.040 --> 0:04:37.680
<v Speaker 1>in various types of box stores where the big ticket,

0:04:37.880 --> 0:04:41.159
<v Speaker 1>very popular items, maybe very far from the entrance that

0:04:41.200 --> 0:04:43.359
<v Speaker 1>requires you to walk through the rest of the store

0:04:43.880 --> 0:04:46.400
<v Speaker 1>in order to take a look at those things. These

0:04:46.480 --> 0:04:50.640
<v Speaker 1>areas that have a high interest level, and the hope

0:04:50.720 --> 0:04:53.000
<v Speaker 1>is that along the way you'll see something else that

0:04:53.040 --> 0:04:55.080
<v Speaker 1>catches your eye and you'll pick that up. To Now,

0:04:55.120 --> 0:04:59.560
<v Speaker 1>stores will experiment with where certain products should sit on shelves.

0:05:00.080 --> 0:05:04.080
<v Speaker 1>Sometimes you might display one product a shelf higher than

0:05:04.640 --> 0:05:06.839
<v Speaker 1>what it was on before, and that's all it will

0:05:06.839 --> 0:05:10.800
<v Speaker 1>take to move more units. Large chains might use certain

0:05:10.800 --> 0:05:13.200
<v Speaker 1>stores as test sites and they'll work on a new

0:05:13.279 --> 0:05:16.760
<v Speaker 1>layout configuration on this test site to see how well

0:05:16.760 --> 0:05:19.200
<v Speaker 1>it plays out in that market before they make a

0:05:19.200 --> 0:05:21.240
<v Speaker 1>decision about whether or not they'll roll it out to

0:05:21.279 --> 0:05:25.400
<v Speaker 1>everybody else. This is essentially what we call a B testing.

0:05:25.920 --> 0:05:28.560
<v Speaker 1>So a B testing is something that you see in

0:05:28.600 --> 0:05:32.680
<v Speaker 1>website design where you've got someone creating a website layout

0:05:32.680 --> 0:05:38.000
<v Speaker 1>typically and they deploy that layout so that some users

0:05:38.080 --> 0:05:40.839
<v Speaker 1>when they come to visit the site, see version A

0:05:41.240 --> 0:05:45.280
<v Speaker 1>of a website. Some users see version B, and then

0:05:45.279 --> 0:05:49.400
<v Speaker 1>they analyze the behaviors of users on A versus B

0:05:49.960 --> 0:05:54.040
<v Speaker 1>and see if there is a measurable difference in behaviors

0:05:54.080 --> 0:05:56.960
<v Speaker 1>so that you can determine well, it turns out that

0:05:57.200 --> 0:06:00.760
<v Speaker 1>version A people are not sticking around very long, the

0:06:00.839 --> 0:06:03.920
<v Speaker 1>version B people are engaged much more with the content

0:06:03.960 --> 0:06:06.920
<v Speaker 1>of the website. So this is a way of testing

0:06:06.960 --> 0:06:12.040
<v Speaker 1>out different approaches, different design layouts in order to determine

0:06:12.040 --> 0:06:15.119
<v Speaker 1>what is the most effective one. And it's the same

0:06:15.200 --> 0:06:18.960
<v Speaker 1>thing that we see in the real world. Uh, they

0:06:19.000 --> 0:06:23.159
<v Speaker 1>scrutinize web ALEXA is scrutinized Internet user behavior to get

0:06:23.160 --> 0:06:25.920
<v Speaker 1>a deeper understanding of what people want and what they

0:06:26.000 --> 0:06:31.520
<v Speaker 1>like so that website designers and advertisers can tweak their

0:06:31.560 --> 0:06:34.080
<v Speaker 1>approaches to tap into that and get the best result.

0:06:34.680 --> 0:06:37.320
<v Speaker 1>That result might be to get people to subscribe to

0:06:37.360 --> 0:06:40.880
<v Speaker 1>a service, to purchase products, to support a nonprofit, or

0:06:40.920 --> 0:06:45.080
<v Speaker 1>just spend more time on the web page. So let's

0:06:45.080 --> 0:06:47.960
<v Speaker 1>talk about how this might play out using actual web

0:06:48.000 --> 0:06:50.120
<v Speaker 1>pages as an example. And I'm going to use how

0:06:50.200 --> 0:06:53.200
<v Speaker 1>Stuff Works dot Com as an example because I used

0:06:53.240 --> 0:06:56.640
<v Speaker 1>to write articles for that site and I was in

0:06:56.880 --> 0:06:59.640
<v Speaker 1>meetings where we were talking about site design and what

0:06:59.720 --> 0:07:01.280
<v Speaker 1>was in iportant and the elements that we're going to

0:07:01.320 --> 0:07:03.280
<v Speaker 1>go into play and how that was going to change things.

0:07:04.080 --> 0:07:07.640
<v Speaker 1>And so I've seen a lot about the ways that

0:07:07.720 --> 0:07:11.040
<v Speaker 1>people will analyze traffic data and try to use that

0:07:11.600 --> 0:07:15.800
<v Speaker 1>to help guide decisions for form and content. So How

0:07:15.840 --> 0:07:20.600
<v Speaker 1>Stuff Works, like many websites, generates revenue from ads placed

0:07:20.640 --> 0:07:23.080
<v Speaker 1>on the page. This is at the very heart of

0:07:23.160 --> 0:07:26.680
<v Speaker 1>why web analytics are so important. It's because of the

0:07:26.800 --> 0:07:32.160
<v Speaker 1>revenue model for making money on the web. The very

0:07:32.200 --> 0:07:36.280
<v Speaker 1>hard and soul of that is web advertising. So ads

0:07:36.360 --> 0:07:39.960
<v Speaker 1>can be based on a per click basis. That means

0:07:39.960 --> 0:07:42.480
<v Speaker 1>the advertiser only pays the web page for the actual

0:07:42.560 --> 0:07:46.239
<v Speaker 1>number of clicks the ads generate. So if the ads

0:07:46.320 --> 0:07:48.640
<v Speaker 1>do not get many clicks, the web page does not

0:07:48.760 --> 0:07:51.640
<v Speaker 1>make very much money. There are other variations of this,

0:07:51.720 --> 0:07:55.520
<v Speaker 1>but it's a general approach. There are things that you

0:07:55.560 --> 0:07:58.960
<v Speaker 1>can do to help engage more clicks. The positioning of

0:07:58.960 --> 0:08:00.960
<v Speaker 1>the ad on the web page but comes really important.

0:08:01.280 --> 0:08:03.880
<v Speaker 1>But the other important element is making sure the ads

0:08:03.920 --> 0:08:06.440
<v Speaker 1>actually appealed to the site's users. If you have a

0:08:06.480 --> 0:08:10.280
<v Speaker 1>fan page set up for a cartoon show, for example,

0:08:10.520 --> 0:08:13.600
<v Speaker 1>and you show ads that are for a professional video

0:08:13.680 --> 0:08:17.960
<v Speaker 1>conferencing service for medium to big businesses, that might not

0:08:18.040 --> 0:08:21.480
<v Speaker 1>get very many clicks because the ads that you're displaying

0:08:22.000 --> 0:08:27.040
<v Speaker 1>don't necessarily appeal to the audience coming to your website. Now,

0:08:27.080 --> 0:08:30.160
<v Speaker 1>the other approach besides this per click basis is to

0:08:30.240 --> 0:08:33.440
<v Speaker 1>have a fixed rate ad. Now, these ads have a

0:08:33.520 --> 0:08:37.920
<v Speaker 1>set rate, as I just mentioned, and typically that is

0:08:38.000 --> 0:08:42.120
<v Speaker 1>defined as per impressions or page views. So if you

0:08:42.160 --> 0:08:45.040
<v Speaker 1>hear people talk about impressions, they're really talking about how

0:08:45.040 --> 0:08:48.360
<v Speaker 1>many times has a device loaded that page. That is

0:08:48.480 --> 0:08:52.480
<v Speaker 1>an impression. The more page views a site gets, the

0:08:52.600 --> 0:08:55.079
<v Speaker 1>more money it will make off the ads that are

0:08:55.160 --> 0:08:57.760
<v Speaker 1>on those pages. And typically we measure this in the

0:08:57.920 --> 0:09:02.440
<v Speaker 1>thousands using the unit CPS. That's cost per meal meal

0:09:02.520 --> 0:09:04.880
<v Speaker 1>being one thousand m I L l E. So it's

0:09:04.920 --> 0:09:08.079
<v Speaker 1>not one million, it's one thousand. So if a website

0:09:08.160 --> 0:09:12.760
<v Speaker 1>charges advertisers or rate of two dollars CPM, that means

0:09:13.080 --> 0:09:16.319
<v Speaker 1>the advertiser will pay the publisher two dollars for every

0:09:16.440 --> 0:09:20.760
<v Speaker 1>one thousand impressions or page views that page generates that

0:09:20.800 --> 0:09:25.120
<v Speaker 1>has the ad on it. Right, So the ideas that well,

0:09:25.240 --> 0:09:27.880
<v Speaker 1>we've we've shown that this page has been loaded one

0:09:27.880 --> 0:09:31.199
<v Speaker 1>thousand times. Uh, that means your ad has been viewed

0:09:31.400 --> 0:09:36.839
<v Speaker 1>one thousand times on on various devices, not necessarily by

0:09:36.880 --> 0:09:39.640
<v Speaker 1>one thousand people, because if you have a website that

0:09:39.920 --> 0:09:44.880
<v Speaker 1>reloads frequently for some reason or another, then those uh,

0:09:44.960 --> 0:09:49.960
<v Speaker 1>those impressions could represent fewer than a thousand people, but

0:09:49.960 --> 0:09:52.760
<v Speaker 1>it would still be one thousand impressions you would get

0:09:52.760 --> 0:09:57.040
<v Speaker 1>the two dollars. Page Views and people are two very

0:09:57.080 --> 0:09:59.360
<v Speaker 1>different things. If you can rack up a large number

0:09:59.360 --> 0:10:02.000
<v Speaker 1>of page views with a limited number of people, that

0:10:02.120 --> 0:10:05.520
<v Speaker 1>still counts towards CPM. And this is why so many

0:10:05.600 --> 0:10:09.720
<v Speaker 1>web pages have things like quizzes or image galleries or

0:10:09.760 --> 0:10:13.640
<v Speaker 1>slide shows. Each time the page refreshes to give you

0:10:13.640 --> 0:10:16.679
<v Speaker 1>a new question or a new hilarious cat meme, that's

0:10:16.720 --> 0:10:19.959
<v Speaker 1>an impression. That's a page view. So if you've ever

0:10:20.040 --> 0:10:23.040
<v Speaker 1>gone to an article where it's not really an article,

0:10:23.080 --> 0:10:25.240
<v Speaker 1>it's a slide show and you have to click next

0:10:25.320 --> 0:10:29.960
<v Speaker 1>after each thing. This is largely why because it's a

0:10:29.960 --> 0:10:34.240
<v Speaker 1>way to engage the user to keep on clicking through

0:10:34.320 --> 0:10:37.280
<v Speaker 1>and refreshing the page, and it's a way to generate

0:10:37.360 --> 0:10:40.840
<v Speaker 1>those impressions. And the math is simple. Why would you

0:10:40.880 --> 0:10:44.360
<v Speaker 1>create a web page with the top twenty comedy movies

0:10:44.440 --> 0:10:46.960
<v Speaker 1>of all time and you put it all on one

0:10:47.000 --> 0:10:50.839
<v Speaker 1>page so you get one impression per visitor when they

0:10:50.880 --> 0:10:53.520
<v Speaker 1>come in to read your article. Or you could do

0:10:53.600 --> 0:10:57.000
<v Speaker 1>the smart thing, you create a slide show, and you

0:10:57.000 --> 0:11:00.800
<v Speaker 1>could potentially get twenty page views per visitor. Now, not

0:11:00.920 --> 0:11:03.800
<v Speaker 1>every visitor is going to stick around for all twenty items,

0:11:04.360 --> 0:11:07.679
<v Speaker 1>but even if they only show up and bounce, like

0:11:07.720 --> 0:11:10.680
<v Speaker 1>they see the first page and they see, oh, this

0:11:10.800 --> 0:11:12.360
<v Speaker 1>is a slide show, I don't want to use this,

0:11:12.480 --> 0:11:16.080
<v Speaker 1>and they go away, You're not gonna get fewer impressions

0:11:16.320 --> 0:11:18.360
<v Speaker 1>than if they were all on the same page. Right.

0:11:18.880 --> 0:11:23.600
<v Speaker 1>If you attract ten thou people, let's say, to your

0:11:24.080 --> 0:11:27.400
<v Speaker 1>one page version of the top twenty movies comedy movies

0:11:27.440 --> 0:11:31.120
<v Speaker 1>of all time, and they read the whole thing, that's great.

0:11:31.720 --> 0:11:35.200
<v Speaker 1>If you attract ten thousand to your slide show and

0:11:36.320 --> 0:11:38.720
<v Speaker 1>eight thousand of them just look at that first page

0:11:38.720 --> 0:11:42.240
<v Speaker 1>and they leave, but the other two thousand start clicking

0:11:42.280 --> 0:11:44.960
<v Speaker 1>at least a little bit, You've generated more than ten

0:11:45.000 --> 0:11:49.520
<v Speaker 1>thousand impressions. So it is a strategy that works, which

0:11:49.559 --> 0:11:51.880
<v Speaker 1>is why you see it out there now. I am

0:11:51.960 --> 0:11:54.960
<v Speaker 1>not a huge fan of that particular type of web

0:11:55.000 --> 0:11:58.280
<v Speaker 1>design from a user perspective, but from a business perspective,

0:11:58.720 --> 0:12:02.600
<v Speaker 1>I totally get it. It's a page view manufacturing machine,

0:12:03.000 --> 0:12:06.240
<v Speaker 1>and if the industry depends upon page views as a

0:12:06.280 --> 0:12:11.199
<v Speaker 1>way of measuring engagement and therefore tied to revenue, then

0:12:11.240 --> 0:12:14.080
<v Speaker 1>finding ways to maximize page views is always going to

0:12:14.120 --> 0:12:18.080
<v Speaker 1>be a priority. It's not necessarily the quality of the interaction,

0:12:18.440 --> 0:12:22.800
<v Speaker 1>but the quantity the number of impressions. However, quality can

0:12:22.880 --> 0:12:25.839
<v Speaker 1>matter too, and that's because websites have to first figure

0:12:25.880 --> 0:12:29.200
<v Speaker 1>out how much do they charge for those CPMs. You know,

0:12:29.200 --> 0:12:31.560
<v Speaker 1>I gave that two dollar figure, but that was just

0:12:31.640 --> 0:12:35.719
<v Speaker 1>a random example. A site that can demonstrate that its

0:12:35.800 --> 0:12:39.439
<v Speaker 1>users feel they're getting a really good quality experience can

0:12:39.440 --> 0:12:43.240
<v Speaker 1>typically demand much higher rates than other sites. If you

0:12:43.320 --> 0:12:45.920
<v Speaker 1>have a lot of traffic coming to your website, and

0:12:46.000 --> 0:12:48.400
<v Speaker 1>you can also demonstrate that the people who come to

0:12:48.440 --> 0:12:52.120
<v Speaker 1>your website are really engaged, they really stick around. They

0:12:52.920 --> 0:12:56.320
<v Speaker 1>often will explore the website or stay on pages for

0:12:56.360 --> 0:12:59.319
<v Speaker 1>a very long time. That shows that you have a

0:12:59.400 --> 0:13:02.000
<v Speaker 1>higher value you then a website that might get a

0:13:02.000 --> 0:13:04.200
<v Speaker 1>lot of people coming in, but then immediately they leave.

0:13:04.920 --> 0:13:09.000
<v Speaker 1>So this ties into a concept called bounce rate I

0:13:09.040 --> 0:13:12.480
<v Speaker 1>mentioned bounce earlier. Bounce rate refers to the percentage of

0:13:12.559 --> 0:13:16.920
<v Speaker 1>website visitors who leave or bounce after viewing just one page,

0:13:16.960 --> 0:13:19.920
<v Speaker 1>like a landing page or a home page. You want

0:13:19.920 --> 0:13:22.360
<v Speaker 1>your bounce rate to be really low because you want

0:13:22.440 --> 0:13:24.760
<v Speaker 1>visitors to be engaged in your site. You want them

0:13:24.800 --> 0:13:27.439
<v Speaker 1>to not just come to the landing page, but maybe

0:13:27.440 --> 0:13:29.240
<v Speaker 1>click on some of the links that go to other

0:13:29.280 --> 0:13:32.360
<v Speaker 1>pages in your website, and it shows that your site

0:13:32.360 --> 0:13:35.600
<v Speaker 1>has value. Plus, chances are you want people engage because

0:13:35.640 --> 0:13:38.080
<v Speaker 1>you put a lot of work into a website, and

0:13:38.080 --> 0:13:40.480
<v Speaker 1>it would be depressing if no one ever went beyond

0:13:40.520 --> 0:13:43.600
<v Speaker 1>a single page view. You know, why would you go

0:13:43.720 --> 0:13:49.880
<v Speaker 1>through the trouble of designing a fully engrossing website when

0:13:49.920 --> 0:13:52.520
<v Speaker 1>everyone just comes to one page on that site and

0:13:52.559 --> 0:13:54.800
<v Speaker 1>then they say, no, I'm out of here. That would

0:13:54.800 --> 0:13:58.560
<v Speaker 1>be really upsetting. And so a low bounce rate tends

0:13:58.600 --> 0:14:00.480
<v Speaker 1>to look really good to advertise. There's this is a

0:14:00.480 --> 0:14:03.760
<v Speaker 1>signal that says users value their time here, and so

0:14:03.840 --> 0:14:06.880
<v Speaker 1>you're advertising will be featured on a really good website.

0:14:07.200 --> 0:14:11.000
<v Speaker 1>And again, another important quantity to measure is the amount

0:14:11.000 --> 0:14:13.559
<v Speaker 1>of time people will spend on a web page. Do

0:14:13.600 --> 0:14:15.400
<v Speaker 1>you want that number to be high so you want

0:14:15.400 --> 0:14:17.480
<v Speaker 1>the bounce right to be low. The amount of time

0:14:17.520 --> 0:14:19.640
<v Speaker 1>spent on a web page to be high. That shows

0:14:19.640 --> 0:14:22.760
<v Speaker 1>people are spending more time on your service. That's attractive

0:14:22.760 --> 0:14:26.160
<v Speaker 1>to advertisers. It's a great way to demand higher CPM

0:14:26.240 --> 0:14:29.120
<v Speaker 1>rates if you can demonstrate that users come to your

0:14:29.160 --> 0:14:31.440
<v Speaker 1>site and spend a lot of time there. For one

0:14:31.440 --> 0:14:33.760
<v Speaker 1>thing that tells advertisers your site is a good spot

0:14:33.800 --> 0:14:36.560
<v Speaker 1>to reach people. If the time spent on your pages

0:14:36.760 --> 0:14:40.520
<v Speaker 1>is low. That might tell advertisers, hey, you know, maybe

0:14:40.560 --> 0:14:42.560
<v Speaker 1>don't put ads here because no one is spending enough

0:14:42.600 --> 0:14:45.400
<v Speaker 1>time on an individual page to even register that there

0:14:45.560 --> 0:14:48.280
<v Speaker 1>is an ad. If the average time spent on a

0:14:48.280 --> 0:14:50.200
<v Speaker 1>page on your site is half a minute or less

0:14:50.200 --> 0:14:53.720
<v Speaker 1>and you have lots of long articles, that indicates that

0:14:53.760 --> 0:14:57.200
<v Speaker 1>most users aren't actually reading the content you've created, and

0:14:57.240 --> 0:14:59.920
<v Speaker 1>that is not a good thing. So you want your

0:15:00.000 --> 0:15:01.800
<v Speaker 1>once right low. You want the amount of time you

0:15:01.840 --> 0:15:04.600
<v Speaker 1>spent spent on an individual page on your site to

0:15:04.640 --> 0:15:07.520
<v Speaker 1>be high, and that will keep advertisers interested in your

0:15:07.560 --> 0:15:09.960
<v Speaker 1>site as a place where ads may be most effective.

0:15:10.160 --> 0:15:13.960
<v Speaker 1>Beyond that, knowing that your users like one thing over

0:15:14.000 --> 0:15:16.680
<v Speaker 1>another in general is really helpful because it can help

0:15:16.760 --> 0:15:22.200
<v Speaker 1>you match up advertisers that are most appropriate for your demographic. Again,

0:15:22.560 --> 0:15:25.360
<v Speaker 1>let's going back to that fictional fan page I talked

0:15:25.360 --> 0:15:28.000
<v Speaker 1>about creating a fan site for a cartoon show. Let's

0:15:28.000 --> 0:15:30.360
<v Speaker 1>say you've done that and you've got great engagement, You've

0:15:30.360 --> 0:15:32.280
<v Speaker 1>got a really low bounce rate. People are spending a

0:15:32.280 --> 0:15:35.160
<v Speaker 1>good amount of time on your page and they're exploring

0:15:35.200 --> 0:15:38.600
<v Speaker 1>the various links on there. Then maybe you reach out

0:15:38.640 --> 0:15:41.960
<v Speaker 1>and you find an online store that sells merchandise related

0:15:42.080 --> 0:15:44.400
<v Speaker 1>to the show that your site is a fan site of.

0:15:44.480 --> 0:15:48.760
<v Speaker 1>That's a no brainer. That's a perfect relationship, and you

0:15:48.800 --> 0:15:53.000
<v Speaker 1>could probably demand decent CPMs for that, and ideally everyone benefits.

0:15:53.040 --> 0:15:56.240
<v Speaker 1>The advertiser gets a good spot to show ads, visitors

0:15:56.280 --> 0:15:59.640
<v Speaker 1>to the website have the opportunity to purchase merchandise related

0:15:59.680 --> 0:16:03.200
<v Speaker 1>to the show they love, you earn money from the impressions.

0:16:03.720 --> 0:16:09.800
<v Speaker 1>That's the idea. So generally speaking, it's not the worst

0:16:09.800 --> 0:16:12.080
<v Speaker 1>thing in the world, right this web analytics. It's the

0:16:12.120 --> 0:16:16.040
<v Speaker 1>idea of not just the advertising part, although that plays

0:16:16.080 --> 0:16:18.880
<v Speaker 1>a big part of this, but also what do my

0:16:18.960 --> 0:16:22.600
<v Speaker 1>users like? And how can I make my website more

0:16:22.760 --> 0:16:24.560
<v Speaker 1>of what my users like? How can I get rid

0:16:24.600 --> 0:16:27.800
<v Speaker 1>of stuff they don't like? How can I emphasize stuff

0:16:27.800 --> 0:16:30.560
<v Speaker 1>they do like and make a better experience so that

0:16:30.640 --> 0:16:34.480
<v Speaker 1>the work I put in is rewarded and I feel

0:16:34.520 --> 0:16:37.320
<v Speaker 1>good about what I've done, right, Like, I feel a

0:16:37.320 --> 0:16:41.960
<v Speaker 1>sense of accomplishment because I've created something that people value. Uh,

0:16:42.200 --> 0:16:45.800
<v Speaker 1>It's a very powerful feeling. Now, I got a lot

0:16:45.840 --> 0:16:48.120
<v Speaker 1>more to say about web analytics, but before I get

0:16:48.160 --> 0:16:50.320
<v Speaker 1>into any more of that, let's take a quick break

0:16:50.360 --> 0:17:02.000
<v Speaker 1>to thank our sponsor. Right to actually measure stuff like

0:17:02.120 --> 0:17:05.480
<v Speaker 1>bounce rate, time spent on pages, user preferences. We rely

0:17:05.960 --> 0:17:09.520
<v Speaker 1>on web analytics, and there are companies that specialize in

0:17:09.560 --> 0:17:14.320
<v Speaker 1>providing web analytics tools. Google is one of the big ones. Uh.

0:17:14.359 --> 0:17:17.439
<v Speaker 1>These services provide a ton of information to website owners

0:17:17.440 --> 0:17:19.320
<v Speaker 1>to help them keep an eye on how things are

0:17:19.359 --> 0:17:22.399
<v Speaker 1>going and how to react nimbly when an opportunity or

0:17:22.480 --> 0:17:27.000
<v Speaker 1>a crisis arises. The web analysis depends not only on tools,

0:17:27.359 --> 0:17:31.640
<v Speaker 1>but also some assumptions, and one of those assumptions is intent.

0:17:32.560 --> 0:17:35.879
<v Speaker 1>When you look at an analysis, you are assuming that

0:17:35.920 --> 0:17:40.600
<v Speaker 1>the behavior you're studying was intentional. So let's say again,

0:17:40.680 --> 0:17:44.040
<v Speaker 1>let's let's start with how stuffworks dot com. That site

0:17:44.040 --> 0:17:47.880
<v Speaker 1>has a lot of individual pages, hundreds hundreds of pages.

0:17:48.359 --> 0:17:52.280
<v Speaker 1>There are thousands of articles about all sorts of different subjects,

0:17:52.280 --> 0:17:55.840
<v Speaker 1>from technology to culture, to finance, everything else. There's a

0:17:55.880 --> 0:17:59.840
<v Speaker 1>home page which features links to new articles. There's probably

0:18:00.080 --> 0:18:03.359
<v Speaker 1>older articles up there that are maybe timely because of

0:18:03.400 --> 0:18:05.680
<v Speaker 1>something that's going on in the news, or maybe there's

0:18:05.720 --> 0:18:08.560
<v Speaker 1>some classic articles that are mixed in because they've consistently

0:18:08.600 --> 0:18:12.920
<v Speaker 1>performed well over time, so they're they're dependable whatever the case.

0:18:13.040 --> 0:18:15.480
<v Speaker 1>There are several links on the homepage that go directly

0:18:15.560 --> 0:18:18.000
<v Speaker 1>to articles, so you click on that and you're in

0:18:18.040 --> 0:18:21.720
<v Speaker 1>an article. There are also links that go to channel pages.

0:18:22.200 --> 0:18:26.080
<v Speaker 1>These are broader categories of topics like computers or electronics,

0:18:26.080 --> 0:18:28.000
<v Speaker 1>so you can click on that and go to the

0:18:28.160 --> 0:18:31.639
<v Speaker 1>homepage for that channel. And then there's also a search

0:18:31.680 --> 0:18:35.119
<v Speaker 1>engine tool so that you can actually search for articles

0:18:35.240 --> 0:18:38.440
<v Speaker 1>about a specific topic. If there's something you have in mind. Now,

0:18:38.440 --> 0:18:41.760
<v Speaker 1>when you're analyzing web traffic across the site, you want

0:18:41.800 --> 0:18:44.760
<v Speaker 1>to take close look at all the behavior. You want

0:18:44.800 --> 0:18:47.440
<v Speaker 1>to see how many people clicked into an article from

0:18:47.480 --> 0:18:52.920
<v Speaker 1>the homepage versus going through a channel link, like something

0:18:52.960 --> 0:18:56.840
<v Speaker 1>that was linked through going through one of those channel

0:18:57.400 --> 0:19:00.359
<v Speaker 1>landing pages or using a search engine. You want to

0:19:00.359 --> 0:19:03.280
<v Speaker 1>see how many people clicked into an article from an

0:19:03.280 --> 0:19:07.240
<v Speaker 1>external search engine, or maybe a piece of content somewhere

0:19:07.280 --> 0:19:09.040
<v Speaker 1>else on the web, something that's not on one of

0:19:09.080 --> 0:19:11.960
<v Speaker 1>your web pages but is linked from someone else's to

0:19:12.080 --> 0:19:15.600
<v Speaker 1>your site, or from a social media platform. There might

0:19:15.640 --> 0:19:20.280
<v Speaker 1>be social media marketing campaigns that you're running, and you

0:19:20.320 --> 0:19:22.720
<v Speaker 1>want to include a little string of data that will

0:19:22.800 --> 0:19:25.680
<v Speaker 1>let you know if someone's clicking into that article from

0:19:25.680 --> 0:19:28.879
<v Speaker 1>say Twitter or Facebook. All of that is valuable information

0:19:28.960 --> 0:19:31.160
<v Speaker 1>and it helps you figure out how were your well

0:19:31.160 --> 0:19:33.560
<v Speaker 1>your design works. So if most of your traffic is

0:19:33.560 --> 0:19:37.000
<v Speaker 1>coming in through search, it means you perform well when

0:19:37.000 --> 0:19:39.960
<v Speaker 1>people search stuff in in engines like Google. Like they're

0:19:40.000 --> 0:19:42.520
<v Speaker 1>looking for a topic in Google and your site is

0:19:42.560 --> 0:19:45.640
<v Speaker 1>popping up. That's great, Hey, you've got great seo. Your

0:19:45.920 --> 0:19:50.160
<v Speaker 1>website is is up in the first few uh selections

0:19:50.359 --> 0:19:54.880
<v Speaker 1>in a search engine. And we know from research that

0:19:54.960 --> 0:19:57.359
<v Speaker 1>if you are on the first page, you have a

0:19:57.400 --> 0:19:59.640
<v Speaker 1>lot better chance of having someone click on your length

0:19:59.680 --> 0:20:04.040
<v Speaker 1>than if you're buried down on page three or lower. Now,

0:20:04.240 --> 0:20:06.320
<v Speaker 1>a lot of people don't go past the second page

0:20:06.359 --> 0:20:09.720
<v Speaker 1>if they don't see what they're looking for. But if

0:20:09.720 --> 0:20:11.600
<v Speaker 1>that's the case, if most of your traffic is coming

0:20:11.600 --> 0:20:14.199
<v Speaker 1>in through search, that might indicate that your homepage is

0:20:14.240 --> 0:20:16.439
<v Speaker 1>not really a popular spot for people to visit just

0:20:16.560 --> 0:20:18.880
<v Speaker 1>on their own. So that might mean you should look

0:20:18.920 --> 0:20:22.240
<v Speaker 1>into a redesign for your homepage to attract more visitors

0:20:22.240 --> 0:20:26.480
<v Speaker 1>to say, this is a website you want to check regularly,

0:20:26.760 --> 0:20:29.359
<v Speaker 1>not just come here when you are searching for something,

0:20:29.400 --> 0:20:32.280
<v Speaker 1>and we happen to have what it is you're searching for.

0:20:32.960 --> 0:20:36.200
<v Speaker 1>But no matter what conclusions you draw from this data,

0:20:36.359 --> 0:20:39.280
<v Speaker 1>you're doing it based on the assumption that the users

0:20:39.400 --> 0:20:44.000
<v Speaker 1>intended to navigate to those links, Whether they did so

0:20:44.080 --> 0:20:46.879
<v Speaker 1>through a search engine, a link on another site, or

0:20:46.880 --> 0:20:51.080
<v Speaker 1>through the home page. Your analysis depends upon that assumption.

0:20:51.600 --> 0:20:54.320
<v Speaker 1>So if people ended up on your site by chance,

0:20:54.840 --> 0:20:58.520
<v Speaker 1>by mistake, that doesn't tell you anything other than there

0:20:58.560 --> 0:21:01.240
<v Speaker 1>may be links to your site that are misleading or

0:21:01.280 --> 0:21:04.600
<v Speaker 1>easy to click on by accident. Um. I'm reminded of

0:21:04.640 --> 0:21:08.640
<v Speaker 1>a lot of older web advertisements that were pop over

0:21:08.760 --> 0:21:12.120
<v Speaker 1>ads that would suddenly show up in front of your

0:21:12.200 --> 0:21:15.159
<v Speaker 1>view on a website, and it was very easy to

0:21:15.200 --> 0:21:17.840
<v Speaker 1>accidentally click on one while you were looking at a website,

0:21:17.840 --> 0:21:19.320
<v Speaker 1>because it would pop up just as you were about

0:21:19.320 --> 0:21:22.280
<v Speaker 1>to click on something else, and you would navigate to

0:21:22.640 --> 0:21:25.560
<v Speaker 1>whatever the ad linked you to. Well, that's not an

0:21:25.600 --> 0:21:30.600
<v Speaker 1>intentional click. That's that's like a shell game. It's smoke

0:21:30.680 --> 0:21:34.760
<v Speaker 1>and mirrors. It's it's tricking you, scamming you into clicking,

0:21:35.240 --> 0:21:38.520
<v Speaker 1>not to fool you or not to convince you to

0:21:38.560 --> 0:21:42.080
<v Speaker 1>buy anything, but because that makes it look really good

0:21:42.359 --> 0:21:45.800
<v Speaker 1>to your clients. Right, if you are a company that

0:21:46.359 --> 0:21:49.760
<v Speaker 1>that places ads on stuff and you can turn to

0:21:49.800 --> 0:21:52.520
<v Speaker 1>a potential client and say, here's the number of clicks

0:21:52.560 --> 0:21:56.000
<v Speaker 1>that are last campaign generated. Look how how popular it was,

0:21:56.200 --> 0:21:58.240
<v Speaker 1>and you just leave out the little detail that most

0:21:58.280 --> 0:22:02.280
<v Speaker 1>of those clicks were gathered by subterviews. Then you might

0:22:02.320 --> 0:22:06.520
<v Speaker 1>be able to land the juicy contract. It's not very ethical,

0:22:06.680 --> 0:22:09.119
<v Speaker 1>but it did happen quite a bit. Doesn't happen so

0:22:09.200 --> 0:22:12.040
<v Speaker 1>much in that format anymore. I'm sure it happens like

0:22:12.080 --> 0:22:16.679
<v Speaker 1>crazy and other formats still, So accidental traffic might count

0:22:16.760 --> 0:22:20.640
<v Speaker 1>the same as intentional when you're looking at number of impressions,

0:22:21.119 --> 0:22:23.679
<v Speaker 1>but it's not exactly a healthy business strategy because your

0:22:23.680 --> 0:22:26.280
<v Speaker 1>bounce rate is going to be super high, your time

0:22:26.320 --> 0:22:28.480
<v Speaker 1>spent on a website it's gonna be super low. That

0:22:28.600 --> 0:22:33.879
<v Speaker 1>people are going to associate the destination they went to

0:22:34.160 --> 0:22:37.280
<v Speaker 1>as an untrustworthy source, So it is a losing game

0:22:37.320 --> 0:22:40.640
<v Speaker 1>in the long run. So intention is a very important

0:22:40.640 --> 0:22:44.000
<v Speaker 1>concept in web analysis, particularly when you pair that concept

0:22:44.080 --> 0:22:46.320
<v Speaker 1>with other behaviors. So if you see a lot of

0:22:46.320 --> 0:22:48.840
<v Speaker 1>people are clicking into an article from the home page

0:22:48.880 --> 0:22:51.080
<v Speaker 1>of how Stuff Works, but then you see the bounce

0:22:51.160 --> 0:22:53.240
<v Speaker 1>rate on the article is very high, and the time

0:22:53.280 --> 0:22:55.919
<v Speaker 1>spent on the article is very low. It indicates that

0:22:56.800 --> 0:22:59.080
<v Speaker 1>what you've got it that link is not meeting the

0:22:59.119 --> 0:23:03.080
<v Speaker 1>expectation of visitors. Right they see a headline, they click

0:23:03.160 --> 0:23:07.480
<v Speaker 1>on it, they immediately back out or navigate away. That

0:23:07.560 --> 0:23:11.119
<v Speaker 1>tells you something is going wrong there. Either the article

0:23:11.240 --> 0:23:14.440
<v Speaker 1>is not a very good one, or the link was misleading.

0:23:14.440 --> 0:23:18.760
<v Speaker 1>Maybe the headline wasn't really appropriate for whatever the article was,

0:23:19.400 --> 0:23:23.280
<v Speaker 1>or maybe it gave mistaken impression that the content was

0:23:23.320 --> 0:23:25.439
<v Speaker 1>going to be in some other factor form factor like

0:23:25.600 --> 0:23:30.160
<v Speaker 1>video or audio. Uh So, if you if you work

0:23:30.160 --> 0:23:32.399
<v Speaker 1>from the assumption that the user intended to click on

0:23:32.400 --> 0:23:34.720
<v Speaker 1>the link and then went to the new page, but

0:23:34.760 --> 0:23:37.440
<v Speaker 1>they didn't like what they saw, it tells you, well,

0:23:37.480 --> 0:23:39.240
<v Speaker 1>I need to fix this. Maybe I need to change

0:23:39.280 --> 0:23:42.800
<v Speaker 1>that headline, or maybe I need to uh make more

0:23:42.880 --> 0:23:46.919
<v Speaker 1>clear what it is this is so that people don't

0:23:47.240 --> 0:23:48.920
<v Speaker 1>click on it and then just bounce away because that

0:23:48.960 --> 0:23:52.600
<v Speaker 1>doesn't look good either. So, using a different example, let's

0:23:52.600 --> 0:23:54.920
<v Speaker 1>say I'm looking at data from how stuff Works dot

0:23:54.960 --> 0:23:58.560
<v Speaker 1>com and I have an article there titled will Artificial

0:23:58.600 --> 0:24:02.320
<v Speaker 1>Intelligence Eliminate Your job? Right there on the home page,

0:24:02.840 --> 0:24:04.359
<v Speaker 1>And I'm looking at the traffic and I see a

0:24:04.400 --> 0:24:06.240
<v Speaker 1>lot of people are clicking on that link, but once

0:24:06.280 --> 0:24:08.280
<v Speaker 1>they get there, they either search for something in the

0:24:08.280 --> 0:24:10.800
<v Speaker 1>search engine or they back out the article. Now, that

0:24:10.840 --> 0:24:13.240
<v Speaker 1>could mean the users are not seeing what they expected

0:24:13.640 --> 0:24:16.680
<v Speaker 1>and the article title maybe isn't appropriate. On the other hand,

0:24:17.000 --> 0:24:18.840
<v Speaker 1>if I see the bounce rate is low and the

0:24:18.920 --> 0:24:21.000
<v Speaker 1>time spent on the page is a good amount, I

0:24:21.040 --> 0:24:24.800
<v Speaker 1>can assume this is an article that's really engaging and interesting,

0:24:25.240 --> 0:24:27.000
<v Speaker 1>and I might want to give it an even more

0:24:27.040 --> 0:24:29.840
<v Speaker 1>prominent placement on the home page to help drive more traffic.

0:24:29.880 --> 0:24:32.199
<v Speaker 1>If I see this is performing really well, let me

0:24:32.200 --> 0:24:35.520
<v Speaker 1>put it on the heroes spot on a carousel so

0:24:35.560 --> 0:24:38.359
<v Speaker 1>that it's the first thing people see when they load

0:24:38.480 --> 0:24:42.719
<v Speaker 1>up the home page and drive even more traffic to it.

0:24:42.880 --> 0:24:45.119
<v Speaker 1>Or I might want to make sure that I include

0:24:45.119 --> 0:24:48.199
<v Speaker 1>the article in the layout the following day. Right, So

0:24:48.280 --> 0:24:50.800
<v Speaker 1>if I have a carousel or slide show type display

0:24:50.880 --> 0:24:53.000
<v Speaker 1>for articles, I might say, all right, well, I'm not

0:24:53.000 --> 0:24:55.160
<v Speaker 1>gonna put it in the first spot because now it's

0:24:55.160 --> 0:24:57.520
<v Speaker 1>a day old, but I will put it in spot

0:24:57.720 --> 0:25:02.440
<v Speaker 1>two or three because there's still a good amount of

0:25:02.480 --> 0:25:05.639
<v Speaker 1>traffic coming into this article. There's a tail to it.

0:25:05.720 --> 0:25:07.840
<v Speaker 1>That's what we call the long tail, where you create

0:25:08.240 --> 0:25:12.040
<v Speaker 1>content that continues to have relevance after you've posted it.

0:25:12.600 --> 0:25:15.560
<v Speaker 1>Or maybe a visitor clicks on the homepage and then

0:25:15.560 --> 0:25:18.560
<v Speaker 1>types in the search engine Turing test because they've been

0:25:18.600 --> 0:25:22.040
<v Speaker 1>inspired by this AI article title, but they're more interested

0:25:22.040 --> 0:25:25.879
<v Speaker 1>in learning about Alan Turing's proposed intelligence test, not about

0:25:25.920 --> 0:25:27.640
<v Speaker 1>whether or not AI is going to take their job.

0:25:28.080 --> 0:25:30.840
<v Speaker 1>And because they use the search engine, I might conclude

0:25:30.840 --> 0:25:34.640
<v Speaker 1>that my homepage doesn't have great navigational tools that will

0:25:34.720 --> 0:25:38.080
<v Speaker 1>lead users to content they want to see. If I

0:25:38.119 --> 0:25:41.240
<v Speaker 1>did have really good navigational tools, then maybe the user

0:25:41.440 --> 0:25:44.000
<v Speaker 1>would see three or four articles that he or she

0:25:44.160 --> 0:25:46.439
<v Speaker 1>is interested in within that same subject. You know, they

0:25:46.480 --> 0:25:49.480
<v Speaker 1>click on a link that would take them to artificial

0:25:49.480 --> 0:25:53.120
<v Speaker 1>intelligence topics, and they might read several articles, and that's

0:25:53.119 --> 0:25:56.440
<v Speaker 1>going to benefit both the user and me. A search

0:25:56.480 --> 0:26:00.639
<v Speaker 1>result will pull up one article, presumably the the article

0:26:00.760 --> 0:26:04.600
<v Speaker 1>that's most relevant to the search terms. Navigation will offer

0:26:04.680 --> 0:26:07.719
<v Speaker 1>up a lot more. Now that being said, personally, I

0:26:07.760 --> 0:26:10.000
<v Speaker 1>often will use search because it gets me to what

0:26:10.080 --> 0:26:12.600
<v Speaker 1>I want a lot faster than just navigating through a

0:26:12.680 --> 0:26:16.280
<v Speaker 1>user interface. I do it for efficiency, but that's something

0:26:16.280 --> 0:26:19.720
<v Speaker 1>that web page designers try to work around to encourage engagement.

0:26:20.200 --> 0:26:23.080
<v Speaker 1>Or let's say that I've given prime position to my

0:26:23.160 --> 0:26:25.480
<v Speaker 1>AI article on the homepage. All right, it's got a

0:26:25.520 --> 0:26:28.399
<v Speaker 1>really good spot on there, but I see that way

0:26:28.440 --> 0:26:31.440
<v Speaker 1>more people are clicking on a totally different article. Uh.

0:26:31.640 --> 0:26:35.080
<v Speaker 1>We'll say it's taking the perfect Instagram photo of your food,

0:26:35.800 --> 0:26:38.600
<v Speaker 1>and that article is performing way better than the AI

0:26:38.720 --> 0:26:43.639
<v Speaker 1>r article. But that article is also featured lower down

0:26:43.640 --> 0:26:46.719
<v Speaker 1>on the homepage, below the fold, as we would say,

0:26:46.800 --> 0:26:48.919
<v Speaker 1>which means it's the point where you would have to

0:26:48.920 --> 0:26:52.520
<v Speaker 1>actually scroll down but beyond the initial homepage view to

0:26:52.680 --> 0:26:56.480
<v Speaker 1>actually see a link to that. Uh. We usually want

0:26:56.480 --> 0:27:00.399
<v Speaker 1>to put the stuff that is really relevant and interesting

0:27:00.480 --> 0:27:03.199
<v Speaker 1>and popular above the fold to make it easier for

0:27:03.240 --> 0:27:05.800
<v Speaker 1>people to see. So that would tell me people are

0:27:05.880 --> 0:27:08.920
<v Speaker 1>not as interested in the AI article as they are

0:27:09.000 --> 0:27:12.080
<v Speaker 1>in the Instagram article, and I should probably swap those

0:27:12.080 --> 0:27:14.600
<v Speaker 1>two out so that the more popular one that has

0:27:14.600 --> 0:27:17.960
<v Speaker 1>a more prominent place and generates more traffic. So how

0:27:18.000 --> 0:27:20.360
<v Speaker 1>do we get that data right? How do we actually

0:27:20.440 --> 0:27:24.520
<v Speaker 1>know what people are doing? Websites tend to have a

0:27:24.600 --> 0:27:29.240
<v Speaker 1>special file called an access log, and this log collects

0:27:29.359 --> 0:27:33.639
<v Speaker 1>raw data about user behavior across a website. An access

0:27:33.720 --> 0:27:36.879
<v Speaker 1>log is essentially a list of all the files that

0:27:37.000 --> 0:27:40.359
<v Speaker 1>users have requested from a website. So remember when you

0:27:40.520 --> 0:27:43.359
<v Speaker 1>visit a website, it means your computer is actually sending

0:27:43.400 --> 0:27:47.520
<v Speaker 1>out a request. This is activated through some interaction you

0:27:47.560 --> 0:27:50.439
<v Speaker 1>have with your web browsers, So you type in a

0:27:50.480 --> 0:27:54.000
<v Speaker 1>web address, you click on a link. Either of those

0:27:54.119 --> 0:27:57.239
<v Speaker 1>is technically a request. It gets sent out over the

0:27:57.240 --> 0:28:02.240
<v Speaker 1>Internet and it shoots over to the appropriate computer system

0:28:02.280 --> 0:28:07.119
<v Speaker 1>that houses those files. That computer processes the request and

0:28:07.200 --> 0:28:09.879
<v Speaker 1>response to it, shooting that file back to you in

0:28:09.920 --> 0:28:13.240
<v Speaker 1>the form of data packets which arrive at your computer,

0:28:13.400 --> 0:28:16.280
<v Speaker 1>get reassembled, and then in your web browser it gets

0:28:16.280 --> 0:28:19.880
<v Speaker 1>displayed as a web page. So for a web page,

0:28:19.920 --> 0:28:22.720
<v Speaker 1>that would be probably an HTML file and all the

0:28:22.760 --> 0:28:25.720
<v Speaker 1>associated files that go along with it, like embedded images

0:28:25.920 --> 0:28:29.120
<v Speaker 1>or other media. The access log keeps count of all

0:28:29.160 --> 0:28:32.480
<v Speaker 1>those requests across all the pages on a site. Now,

0:28:32.520 --> 0:28:35.480
<v Speaker 1>that can be a lot of data, particularly for a

0:28:35.600 --> 0:28:39.160
<v Speaker 1>really big website. So typically to make sense of all

0:28:39.160 --> 0:28:41.200
<v Speaker 1>of that, you would need another program to kind of

0:28:41.240 --> 0:28:43.520
<v Speaker 1>sort through all the information and put it into a

0:28:43.600 --> 0:28:47.960
<v Speaker 1>format that's more easily understood. But access logs are usually

0:28:48.000 --> 0:28:50.920
<v Speaker 1>a little limited in the information they can tell you.

0:28:50.960 --> 0:28:54.000
<v Speaker 1>They can tell you certain types of information, but not

0:28:55.320 --> 0:28:58.320
<v Speaker 1>all the granular stuff. Uh. Information it can tell you

0:28:58.360 --> 0:29:01.479
<v Speaker 1>might include things like the number of unique visitors you have,

0:29:01.880 --> 0:29:06.760
<v Speaker 1>which is uh uh. Which requests represent different devices versus

0:29:06.800 --> 0:29:09.440
<v Speaker 1>those that are linked to a single device. That's what

0:29:09.520 --> 0:29:12.240
<v Speaker 1>we mean by unique visitors. It doesn't again, doesn't necessarily

0:29:12.280 --> 0:29:16.440
<v Speaker 1>mean unique people. It could be the same person using

0:29:16.920 --> 0:29:19.920
<v Speaker 1>ten thousand different devices to access your website. That would

0:29:20.000 --> 0:29:24.520
<v Speaker 1>still be unique visitors because it would all be different devices. Uh.

0:29:24.600 --> 0:29:27.520
<v Speaker 1>The access log might also tell you where the visitors

0:29:27.560 --> 0:29:31.600
<v Speaker 1>associated servers domain name is, like whether the visitors navigating

0:29:31.680 --> 0:29:33.920
<v Speaker 1>from the dot E, d U or dot com or

0:29:33.960 --> 0:29:37.440
<v Speaker 1>dot gov site, or which online service provider the user

0:29:37.600 --> 0:29:40.600
<v Speaker 1>is using, which I s P they are using. The

0:29:40.640 --> 0:29:43.320
<v Speaker 1>access log can tell you which pages on a site

0:29:43.320 --> 0:29:46.400
<v Speaker 1>are getting the most requests. That essentially tells you which

0:29:46.400 --> 0:29:49.320
<v Speaker 1>pages are the most popular across your website. It might

0:29:49.360 --> 0:29:52.160
<v Speaker 1>tell you what times of day or week, or month

0:29:52.280 --> 0:29:55.120
<v Speaker 1>or even year are the most popular to visit your website.

0:29:55.120 --> 0:29:58.320
<v Speaker 1>You can look at trends in data this way, so

0:29:58.360 --> 0:30:00.120
<v Speaker 1>you might see that a lot of people, say, are

0:30:00.200 --> 0:30:03.120
<v Speaker 1>visiting your site in the morning and fewer are visiting

0:30:03.120 --> 0:30:05.080
<v Speaker 1>it in the afternoon, so you might want to make

0:30:05.080 --> 0:30:08.520
<v Speaker 1>sure that you have the fresh content up in the

0:30:08.520 --> 0:30:12.560
<v Speaker 1>mornings so that people are energized to get there. And

0:30:12.640 --> 0:30:15.400
<v Speaker 1>maybe you even experiment, maybe you try and put up

0:30:15.520 --> 0:30:19.000
<v Speaker 1>a second round of new content in the afternoons to

0:30:19.040 --> 0:30:21.640
<v Speaker 1>see if you can encourage more visitors in the afternoons.

0:30:22.200 --> 0:30:24.120
<v Speaker 1>But again, if you have a really big website with

0:30:24.160 --> 0:30:27.120
<v Speaker 1>lots of pages, this approach can get a little unmanageable.

0:30:27.160 --> 0:30:29.080
<v Speaker 1>But there are other ways to get data from users,

0:30:29.120 --> 0:30:31.720
<v Speaker 1>and I'm going to go into that in just a moment,

0:30:31.760 --> 0:30:35.880
<v Speaker 1>but first let's take another quick break to thank our sponsors.

0:30:43.440 --> 0:30:46.800
<v Speaker 1>An alternative to using access logs is using some code

0:30:47.160 --> 0:30:51.320
<v Speaker 1>in JavaScript now. JavaScript is a coding language primarily used

0:30:51.400 --> 0:30:55.400
<v Speaker 1>for web development. Netscape created JavaScript in order to build

0:30:55.400 --> 0:30:58.720
<v Speaker 1>out interactive, dynamic elements in websites, so you didn't just

0:30:58.760 --> 0:31:02.920
<v Speaker 1>have static pages that you never changed and therefore there

0:31:02.960 --> 0:31:05.720
<v Speaker 1>was not really any reason to keep visiting them. It's

0:31:05.760 --> 0:31:09.800
<v Speaker 1>not actually related to the Java programming language directly. It

0:31:09.840 --> 0:31:14.640
<v Speaker 1>did take some inspiration from Java, but JavaScript really resembles

0:31:14.680 --> 0:31:18.560
<v Speaker 1>the c programming language more than Java, and it's a

0:31:18.640 --> 0:31:22.920
<v Speaker 1>client side scripting language. That means your browser processes the

0:31:22.960 --> 0:31:26.720
<v Speaker 1>code rather than the web server. So we have server

0:31:26.840 --> 0:31:30.680
<v Speaker 1>side and we have client side. JavaScript is client side

0:31:31.400 --> 0:31:37.480
<v Speaker 1>JavaScript tracking involves inserting some JavaScript code into a web page. Typically,

0:31:37.480 --> 0:31:40.680
<v Speaker 1>this code will send tracking information to an analytics service

0:31:40.760 --> 0:31:44.520
<v Speaker 1>like Google Analytics, and this gives the service the ability

0:31:44.560 --> 0:31:48.600
<v Speaker 1>to track specific behaviors on web pages that include that

0:31:48.680 --> 0:31:52.720
<v Speaker 1>JavaScript code, including targeted ones that you want to pay

0:31:52.880 --> 0:31:57.200
<v Speaker 1>very close attention to targeted behaviors. Um. For this to work,

0:31:57.520 --> 0:32:00.000
<v Speaker 1>the web designer has to include this code on every

0:32:00.080 --> 0:32:02.400
<v Speaker 1>web page on his or her site that they want

0:32:02.440 --> 0:32:05.040
<v Speaker 1>to track. So when a user visits a web page,

0:32:05.360 --> 0:32:09.320
<v Speaker 1>the user's browser executes the code in JavaScript. Assuming the

0:32:09.400 --> 0:32:13.320
<v Speaker 1>user doesn't have JavaScript turned off. You can turn off JavaScript,

0:32:13.920 --> 0:32:16.480
<v Speaker 1>so if you did that then this step would not happen.

0:32:16.920 --> 0:32:19.320
<v Speaker 1>But when it does happen, it sends what is called

0:32:19.320 --> 0:32:22.240
<v Speaker 1>an API called to the server to send data to

0:32:22.360 --> 0:32:25.880
<v Speaker 1>that server. This type of data is dependent upon the

0:32:25.920 --> 0:32:29.840
<v Speaker 1>code in that JavaScript code and the analysis engine that

0:32:29.920 --> 0:32:32.960
<v Speaker 1>you are using. So if a web developer is only

0:32:33.000 --> 0:32:35.760
<v Speaker 1>interested in where a user is coming from, where that

0:32:35.880 --> 0:32:38.960
<v Speaker 1>user is going, and how long they are, you know

0:32:39.040 --> 0:32:41.760
<v Speaker 1>where they went to after they were on your site

0:32:42.040 --> 0:32:44.880
<v Speaker 1>and how long they were spending on your website. You

0:32:44.920 --> 0:32:47.600
<v Speaker 1>could tweak your JavaScript to only collect that information if

0:32:47.640 --> 0:32:50.920
<v Speaker 1>you wanted to. But as for where you're coming from,

0:32:51.000 --> 0:32:53.280
<v Speaker 1>it can get a little more granular, in fact, a

0:32:53.280 --> 0:32:56.360
<v Speaker 1>lot more granular than just whether it's a dot com

0:32:56.480 --> 0:32:59.160
<v Speaker 1>or dot e du or dot gov. For example, you

0:32:59.200 --> 0:33:02.280
<v Speaker 1>may have seen links to sites from their official social

0:33:02.320 --> 0:33:06.680
<v Speaker 1>media feeds that contain some characters after the HTM tag

0:33:06.840 --> 0:33:08.920
<v Speaker 1>at the end of the u r L. Those characters

0:33:08.920 --> 0:33:12.200
<v Speaker 1>are codes. They give more information about how the user

0:33:12.320 --> 0:33:16.480
<v Speaker 1>navigated to that page. The web server can't make any

0:33:16.520 --> 0:33:19.040
<v Speaker 1>sense of this information and ignores it. So like when

0:33:19.080 --> 0:33:23.080
<v Speaker 1>your web browser asks for that page, the server looks

0:33:23.120 --> 0:33:25.760
<v Speaker 1>at everything that's after HTM and says, this doesn't make

0:33:25.760 --> 0:33:28.240
<v Speaker 1>any sense to me. Just send them the website and

0:33:28.280 --> 0:33:32.560
<v Speaker 1>they will. But the JavaScript code can see that tag

0:33:32.920 --> 0:33:36.000
<v Speaker 1>and link your visit with the associated social platform links.

0:33:36.000 --> 0:33:38.920
<v Speaker 1>So when you get all the information sent off to

0:33:38.960 --> 0:33:42.080
<v Speaker 1>the analytics company, they can return a report that says

0:33:42.680 --> 0:33:47.480
<v Speaker 1>X percent of your visitors to this particular article got

0:33:47.520 --> 0:33:52.600
<v Speaker 1>there through Facebook, why percent got there from Twitter, and

0:33:52.960 --> 0:33:57.160
<v Speaker 1>z percent came from your homepage, and you know, maybe

0:33:57.360 --> 0:34:00.320
<v Speaker 1>a percent came from search. You can get it broken

0:34:00.320 --> 0:34:02.040
<v Speaker 1>down in all these different ways, so you can really

0:34:02.080 --> 0:34:06.120
<v Speaker 1>see where people are coming in, how they are discovering

0:34:06.160 --> 0:34:09.839
<v Speaker 1>your your content, and that gives you ideas of where

0:34:09.880 --> 0:34:13.000
<v Speaker 1>you should spend your efforts promoting your site. And if

0:34:13.000 --> 0:34:15.399
<v Speaker 1>you see that hardly anyone is coming to your site

0:34:15.400 --> 0:34:19.120
<v Speaker 1>from Facebook, it probably means that your links aren't really

0:34:19.239 --> 0:34:21.560
<v Speaker 1>visible to a lot of people. They're not popping up

0:34:21.560 --> 0:34:23.560
<v Speaker 1>in a lot of news feeds. Facebook is famous for

0:34:23.600 --> 0:34:28.280
<v Speaker 1>tweaking its format several times uh and uh and changing

0:34:28.280 --> 0:34:31.960
<v Speaker 1>things out where you'll hear companies say, like especially content

0:34:32.000 --> 0:34:37.120
<v Speaker 1>companies say, Facebook change their algorithms and now we are

0:34:37.160 --> 0:34:41.920
<v Speaker 1>our traffic has dropped incredibly low because we can't get

0:34:41.920 --> 0:34:44.360
<v Speaker 1>our links out in front of people the way we

0:34:44.480 --> 0:34:48.200
<v Speaker 1>used to. Uh. This lesson, by the way, I think

0:34:48.360 --> 0:34:53.000
<v Speaker 1>is that you should never really commit fully to any

0:34:53.120 --> 0:34:59.640
<v Speaker 1>one social platform as your primary way of reaching potential visitors,

0:34:59.680 --> 0:35:02.880
<v Speaker 1>because as you have no control over whether or not

0:35:02.960 --> 0:35:06.439
<v Speaker 1>that platform will change things, and if they do change things,

0:35:06.520 --> 0:35:08.919
<v Speaker 1>it can it can really hurt you. It's a tough

0:35:09.000 --> 0:35:12.360
<v Speaker 1>lesson to learn. Now that might mean that you would

0:35:12.360 --> 0:35:15.160
<v Speaker 1>have to figure out some other strategy. You might have

0:35:15.200 --> 0:35:19.560
<v Speaker 1>to pay Facebook for a promotion so that your your

0:35:19.640 --> 0:35:23.120
<v Speaker 1>links get promoted in more news feeds and then you

0:35:23.200 --> 0:35:25.359
<v Speaker 1>might get a little more traffic. Or it might mean

0:35:25.440 --> 0:35:27.440
<v Speaker 1>you just have to use a totally different approach to

0:35:27.440 --> 0:35:31.200
<v Speaker 1>try and reach other users. Um, it's it's a tough

0:35:31.320 --> 0:35:34.680
<v Speaker 1>it's a tough situation to be in. JavaScript can also

0:35:34.719 --> 0:35:37.879
<v Speaker 1>track user interactions like downloads as well, so if there

0:35:37.920 --> 0:35:40.880
<v Speaker 1>is downloadable content on a web page, it's possible for

0:35:40.920 --> 0:35:43.439
<v Speaker 1>the web administrator to track all that. You can also

0:35:43.480 --> 0:35:48.719
<v Speaker 1>look at user settings like browser resolutions. You can look

0:35:48.719 --> 0:35:51.239
<v Speaker 1>for browser plug ins. If you've ever used an ad

0:35:51.280 --> 0:35:54.520
<v Speaker 1>blocking program and you've wondered how a website can detect that,

0:35:55.160 --> 0:35:57.080
<v Speaker 1>and it sends you a message saying, hey, we see

0:35:57.080 --> 0:36:00.640
<v Speaker 1>your blocking ads. Would you mind you know, not doing that?

0:36:00.640 --> 0:36:03.520
<v Speaker 1>That could come from a JavaScript code and the web page.

0:36:03.880 --> 0:36:05.759
<v Speaker 1>The JavaScript is able to tell that you've gotten ad

0:36:05.760 --> 0:36:08.000
<v Speaker 1>blocker installed, and it triggers this server to send you

0:36:08.040 --> 0:36:10.279
<v Speaker 1>the message to turn off that ad blocker if you

0:36:10.320 --> 0:36:14.880
<v Speaker 1>want to access the content. JavaScript can identify unique visitors

0:36:14.880 --> 0:36:19.439
<v Speaker 1>by analyzing cookies and the browsers quote unquote fingerprint. So

0:36:19.640 --> 0:36:23.600
<v Speaker 1>what exactly are cookies? I'm sure you heard about Internet cookies. Well,

0:36:23.640 --> 0:36:27.239
<v Speaker 1>those are special little data packets that your browser will

0:36:27.280 --> 0:36:31.000
<v Speaker 1>send to web servers when you visit a website. Uh,

0:36:31.160 --> 0:36:33.800
<v Speaker 1>they can get installed on your web browser. Because you

0:36:33.920 --> 0:36:37.080
<v Speaker 1>visit a web page, it installs a cookie on your

0:36:37.080 --> 0:36:40.719
<v Speaker 1>web browser, and then every time you come back, it

0:36:40.960 --> 0:36:45.080
<v Speaker 1>registers that it's you that you've done this. Uh. This

0:36:45.120 --> 0:36:47.600
<v Speaker 1>is actually a pretty valuable thing. It means that when

0:36:47.640 --> 0:36:50.759
<v Speaker 1>you go to a website, it can register that you

0:36:50.800 --> 0:36:53.960
<v Speaker 1>are a return visitor. And let's say you're using a

0:36:54.040 --> 0:36:57.080
<v Speaker 1>service frequently and you log into that service, like you

0:36:57.120 --> 0:36:59.120
<v Speaker 1>have to have a user name and password, Well, the

0:36:59.160 --> 0:37:03.439
<v Speaker 1>cookie might out so that the service recognizes when you're

0:37:03.920 --> 0:37:06.640
<v Speaker 1>navigating back to that service, so you don't have to

0:37:06.640 --> 0:37:09.240
<v Speaker 1>do the log in all over again. It has already

0:37:09.280 --> 0:37:12.960
<v Speaker 1>registered that you are you and you're fine, or maybe

0:37:13.280 --> 0:37:16.640
<v Speaker 1>you are watching a video or listening to some music

0:37:16.760 --> 0:37:20.200
<v Speaker 1>or something you navigate away. When you navigate back, it

0:37:20.239 --> 0:37:22.520
<v Speaker 1>could pick up right where you left off. Because there

0:37:22.560 --> 0:37:26.080
<v Speaker 1>was a cookie that was installed on your browser, it

0:37:26.160 --> 0:37:30.160
<v Speaker 1>was able to register when you stopped watching or listening

0:37:30.200 --> 0:37:33.319
<v Speaker 1>to something, and then when you return, it recognizes where

0:37:33.360 --> 0:37:35.360
<v Speaker 1>who you are and then goes right back to the

0:37:35.400 --> 0:37:39.080
<v Speaker 1>point where you left off. Cookies are what make that possible.

0:37:39.160 --> 0:37:41.880
<v Speaker 1>But those data packets can send other types of information

0:37:41.880 --> 0:37:45.520
<v Speaker 1>to servers, like which pages you have recently visited, or

0:37:45.560 --> 0:37:48.680
<v Speaker 1>which ones you go to frequently, or topics you might

0:37:48.719 --> 0:37:51.320
<v Speaker 1>have searched for in the past. And that information is

0:37:51.400 --> 0:37:54.200
<v Speaker 1>valuable because it not only tells web administrators more about

0:37:54.280 --> 0:37:57.200
<v Speaker 1>user behavior, it can also be a really valuable tool

0:37:57.320 --> 0:38:01.640
<v Speaker 1>for marketing and advertising companies. This is where targeting advertising

0:38:01.680 --> 0:38:05.880
<v Speaker 1>comes into play. So again, uh, in an ideal implementation,

0:38:06.160 --> 0:38:10.439
<v Speaker 1>one where everybody benefits, targeted advertising would mean you would

0:38:10.440 --> 0:38:13.400
<v Speaker 1>see ads for stuff you were already interested in. You

0:38:13.440 --> 0:38:15.680
<v Speaker 1>would not see ads for stuff that did not pertain

0:38:15.719 --> 0:38:19.319
<v Speaker 1>to you. The advertisers would quote unquote know what you

0:38:19.360 --> 0:38:22.719
<v Speaker 1>are interested in because of web analytics and cookies and

0:38:22.760 --> 0:38:25.280
<v Speaker 1>that kind of thing. The data your computer is sending

0:38:25.320 --> 0:38:29.560
<v Speaker 1>servers gives little bits of information about your interests and desires,

0:38:29.960 --> 0:38:32.719
<v Speaker 1>and if it all works properly and everyone's on the

0:38:32.800 --> 0:38:36.040
<v Speaker 1>up and up, the advertiser sends adds that you're most

0:38:36.120 --> 0:38:39.560
<v Speaker 1>likely to find valuable, and that means that you might

0:38:39.600 --> 0:38:42.120
<v Speaker 1>see an ad that you are legitimately interested in you

0:38:42.160 --> 0:38:46.239
<v Speaker 1>actually want to buy that product or service, so you

0:38:46.360 --> 0:38:49.000
<v Speaker 1>end up doing that because you were informed by that

0:38:49.080 --> 0:38:52.600
<v Speaker 1>ad and everybody's a winner. The web content providers a winner,

0:38:52.680 --> 0:38:55.920
<v Speaker 1>the advertisers a winner, the company you bought the service

0:38:56.000 --> 0:38:57.640
<v Speaker 1>or product for as a winner, and you're a winner

0:38:57.680 --> 0:39:00.440
<v Speaker 1>because you all got what you wanted and it's all

0:39:00.480 --> 0:39:03.759
<v Speaker 1>done without your actual identity being part of that equation.

0:39:04.280 --> 0:39:07.719
<v Speaker 1>The web analytics company doesn't care who you are. They

0:39:07.719 --> 0:39:11.480
<v Speaker 1>care about what you like, so you're a user, a

0:39:11.560 --> 0:39:16.160
<v Speaker 1>website visitor. The advertiser just doesn't have any desire to

0:39:16.200 --> 0:39:19.000
<v Speaker 1>go beyond that. They just want to know what they

0:39:19.040 --> 0:39:23.520
<v Speaker 1>can serve to you that will most UH entice you

0:39:24.000 --> 0:39:28.839
<v Speaker 1>to engage with content and with advertising. That's the ideal implementation,

0:39:28.880 --> 0:39:31.239
<v Speaker 1>but as we know, we do not live in an

0:39:31.280 --> 0:39:35.600
<v Speaker 1>ideal world. Now, you can elect to block JavaScript, and

0:39:35.640 --> 0:39:38.319
<v Speaker 1>you can block cookies that will prevent your browser from

0:39:38.320 --> 0:39:41.120
<v Speaker 1>sending information to web servers in the ways i've described.

0:39:41.680 --> 0:39:44.799
<v Speaker 1>The web access logs will still register when you visit

0:39:44.840 --> 0:39:49.080
<v Speaker 1>a site, not you specifically, but rather that the site

0:39:49.680 --> 0:39:53.600
<v Speaker 1>is UH is one among all the others you've hit

0:39:54.239 --> 0:39:57.560
<v Speaker 1>that day. Now, before I conclude this episode, I want

0:39:57.560 --> 0:40:01.800
<v Speaker 1>to stress that web analytics are gitimate and they are valuable.

0:40:02.440 --> 0:40:05.680
<v Speaker 1>They help website administrators create better sites that people want

0:40:05.680 --> 0:40:08.200
<v Speaker 1>to go to. They help content companies make sure they're

0:40:08.239 --> 0:40:11.600
<v Speaker 1>creating the stuff people want to see. Uh. They help

0:40:11.680 --> 0:40:14.960
<v Speaker 1>online retailers market their products more effectively so that people

0:40:15.000 --> 0:40:17.840
<v Speaker 1>find what they're looking for more easily. They can improve

0:40:17.880 --> 0:40:21.799
<v Speaker 1>the experience for all sides of the equation if they

0:40:21.800 --> 0:40:25.239
<v Speaker 1>are used responsibly. But in our next episode, I'll look

0:40:25.239 --> 0:40:28.160
<v Speaker 1>at how things can go wrong when we aren't careful.

0:40:28.560 --> 0:40:31.719
<v Speaker 1>That wraps up this overview of web analytics and a

0:40:31.719 --> 0:40:34.760
<v Speaker 1>little bit of online advertising, and to explain why it's important.

0:40:35.160 --> 0:40:38.360
<v Speaker 1>In our next episode, we'll talk more about privacy issues

0:40:38.360 --> 0:40:41.520
<v Speaker 1>and security issues. If you have any suggestions for future
