Howdy Moz fans. Today we're going to talk about the IdeaGraph. My name's Ian Lurie, and I want to talk about some critical evolution that's happening in the world of search right now.

Google and other search engines have existed in a world of words and links. Words establish relevance. Links establish connections and authority. The problem with that is Google takes a look at this world of links and words and has a very hard time with what I call random affinities.

Let's say all cyclists like eggplant, or some cyclists like eggplant. Google can't figure that out. There is no way to make that connection. Maybe if every eggplant site on the planet linked to every cycling site on the planet, there would be something there for them, but there really isn't.

So Google exists purely on words and links, which means there's a lot of things that it doesn't pick up on. The things it doesn't pick up on are what I call the IdeaGraph.

The IdeaGraph is something that's always existed. It's not something new. It's this thing that creates these connections that are formed only by people. So things that are totally unrelated, like eggplant and cyclists, and by the way that's not true as far as I know. I'm a cyclist and I hate eggplant. But all these things that randomly connect are part of the IdeaGraph.

The IdeaGraph has been used by marketers for years and years and years. If you walk into a grocery store, and you're going from one aisle to the next and you see these products in semi-random order, there's some research there where they test different configurations and see, if someone's walking to the dairy section way at the back of the store, what products can we put along their walk that they're most likely to pick up? Those products, even if the marketers don't know it, are part of the IdeaGraph, because you could put chocolate there, and maybe the chocolate is what people want, but maybe you should put cleaning supplies there and nobody wants it, because the IdeaGraph doesn't connect them tightly enough.

The other place that you run into issues with the IdeaGraph on search and on the Internet is with authorship and credibility and authority.

Right now, if you write an article, and it gets posted on a third-party site, like The New York Times, and it's a huge hit, and it gets thousands and thousands and thousands of links, you might get a little authority sent back to your site, and your site is sad. See? Sad face website. Because it's not getting all the authority it could. Your post is getting tons. It's happy. But your site is not.

With the IdeaGraph it will be easier because the thing that connects your site to your article is you. So just like you can connect widely varying ideas and concepts, you can also connect everything you contribute to a single central source, which then redistributes that authority.

Now Google is starting to work on this. They're starting to work on how to make this work for them in search results. What they've started to do is build these random affinities. So if you take cyclists and eggplant, theoretically some of the things Google is doing could eventually create this place, this space, where you would be able to tell from Google, and Google would be able to tell you that there is this overlap.

The place that they're starting to do it, I think, remember Google doesn't come and tell us these things, but I think it's Google+. With authorship and publisher, rel=author and rel=publisher, they're actually tying these different things together into a single receptacle into your Google+ profile. Remember, anyone who has Gmail, has a Google+ profile. They may not know it, but they do. Now Google's gathering all sorts of demographic data with that as well.

So what they're doing is, let's say you're using rel=author and you publish posts all over the Internet, good posts. If you're just doing crappy guest blogging, this probably won't work. You'll just send yourself all the lousy credit. You want the good credit. So you write all these posts, and you have the rel=author on the post, and they link back to your Google+ profile.

So your Google+ profile gets more and more authoritative. As it gets more and more authoritative, it redistributes that authority, that connection to all the places you publish. What you end up with is a much more robust way of connecting content to people and ideas to people, and ideas to each other. If you write about cycling on one site and eggplant on another, and they both link back to your Google+ profile, and a lot of other people do that, Google can start to say, "Huh, there might be a connection here. Maybe, with my new enhanced query results, I should think about how I can put these two pieces of information together to provide better search results." And your site ends up happier. See? Happy site. Total limit of my artistic ability.

So that becomes a very powerful tool for creating exactly the right kind of results that we, as human beings, really want, because people create the IdeaGraph. Search engines create the world of words and links, and that's why some people have so much trouble with queries, because they're having to convert their thinking from just ideas to words and links.

So what powers the IdeaGraph is this concept of random affinities. You, as a marketer, can take advantage of that, because as Google figures this out through Google+, you're going to be able to find these affinities, and just like all those aisles in the grocery store, or when you walk into a Starbucks and there's a CD there—you're buying coffee and there's a CD? How do those relate? When you find those random affinities, you can capitalize on them and make your marketing message that much more compelling, because you can find where to put that message in places you might never expect.

An example I like is I went on Amazon once and I searched for "lonely planet," and in the "people who bought this also bought," I found a book on making really great smoothies, which tells me there's this random affinity between people who travel lonely planet style and people who like smoothies. It might be a tiny attachment. It might be a tiny relationship, but it's a great place to do some cross marketing and to target content.

So if you take a look here, if you want to find random affinities and build on them, take a look at the Facebook Ad Planner. When you're building a Facebook ad, you can put in a precise interest, and it'll show you other related precise interests. Those relationships are built almost purely on the people who have them in common. So sometimes there is no match, there's no relationship between those two different concepts or interests, other than the fact that lots of people like them both. So that's a good place to start.

Any site that uses collaborative filtering. So, Amazon, for example. Any site that has "people who bought this also bought that" is a great place to go try this. Go on Amazon and try it and look at "people who bought also bought." You'll find all sorts of cool relationships.

Followerwonk is a fantastic tool for this. This one takes a little more work, but the data you can find is incredible. Let's say you know that Rand is one of your customers. He's a perfect customer, and he's typical of your perfect customer. You can go on Followerwonk and find all the people who follow him and then pull all of their bios, do a little research into the bios and find what other interests those people express.

So they're following Randfish, but maybe a whole bunch of them express an interest in comic books, and it's more than just one or two. It's a big number of them. You just found a random affinity. People who like Rand also like comic books. You can then find this area, and it's always easier to sell and get interest in this area.

Again, you can use that to drive content strategy. You can use that to drive keyword selection in a world where we don't really know what keywords are driving traffic anymore, but we can find out what ideas are. You can use it to target specific messages to people.

The ways you capitalize on this, on your own site you want to make sure that you have rel=author and publisher set up, because that's the most obvious IdeaGraph implementation we have right now, is rel=author and publisher.

Make sure you're using schemas from Schema.org whenever you can. For example, make sure you use the article mark-up on your site because Google's enhanced articles, results that are showing up at the bottom of search results right now, those are powered, in part, by pages that have the article mark-up, or at least there's a very high correlation between them. We don't know if it's causal, but it seems to be.

Use product mark-up and review mark-up. I've seen a few instances and some of my colleagues have seen instances where schema mark-up on a page allows content to show up in search results attributed to that page, even if they're being populated to the page by JavaScript or something else.

Get yourself set up with Google Analytics Demographics, as Google rolls it out. You'll be able to get demographic data and categorical data in Google Analytics based on visitors to your site. Then again, if you have a demographic profile, you can look at the things that that demographic profile is interested in and find those random affinities.

So just to summarize all of this, links and words have worked for a long time, but we're starting to see the limitations of it, particularly with mobile devices and other kinds of search. Google has been trying to find a way to fix this, as has Bing, and they're both working very hard at this. They're trying to build on this thing that has always existed that I call the IdeaGraph, and they're building on it using random affinities. Selling to random affinities is much, much easier. You can find them using lots of tools out on the web like collaborative filtering, Facebook, and Followerwonk. You can take advantage and position your site for it by just making sure that you have these basic mark-up elements in place, and you're already collecting data.

I hope that was helpful to all Moz fans out there, and I look forward to talking to you online. Thanks.
