Google Debunks LSI – Then Shows You How To Do It

WARNING: Advanced SEO Concepts Ahead

Q: What’s the fastest way to cause a riot at an SEO conference?

A: Just mention the words “Latent Semantic Indexing”.

It’s true.

Just about half of the people there will tell you it’s an incredible way to get top search engine rankings; the others will say LSI is a lie or a myth.

What I’m going to share with you today is probably going to cause some controversy, because I use the words “Latent Semantic Indexing” (or LSI)…

…So after I show you this technique, I’m going to put an end to these stupid LSI arguments once-and-for-all.

Perfect LSI Structuring

If you’re creating a site with an LSI silo structure, you can receive a big boost in the rankings that you receive in search engines – put simply, because search engines see you as being more relevant to the topic.

What I’m talking about when I say “LSI silo structure” is categorising content in a logical keyword structure, and grouping content on similar topics together, in a way similar to what search engines expect to see.

And, for the most part, they expect to see tree-like category structures – with categories, sub-categories, and sub-sub-categories all branching off one-another.

The problem is finding the right structure.

If you’re developing a new site, and you’re trying to get the best search engine boost from LSI, how should your content be structured?

What keywords should go where? What should your categories be? What topics should you be building content around?

Or, if you’re actually doing it as part of your core web-site, no-doubt you’re finding categorising content is a pain. You write an article, and then wonder where you should put it to get the maximum benefit.

So you’re always second-guessing the way that the content should be categorised for maximum SEO value – should it go in one category? Or another? – particularly when content can be related to multiple categories.

And once you’ve built categories, how do you know what other topics should go into that category to fill it with the “right” sort of content?

The Google Search-Based Keyword Tool isn’t just good for finding long tail keywords – it’s also fantastic for categorising and grouping keywords.

That’s because the Google Search-Based Keyword Tool is showing you structured, categorised, hierarchical keyword relationships – and blog/site structures tend to be structured, categorised and hierarchical.

And, where keywords are related to multiple categories, it shows you all of them.

Debunking LSI Myths

There’s a lot of confusion about whether or not “LSI” (or Latent Semantic Indexing) is used by Google or not – so let me clarify things.

There’s a lot of convincing evidence suggesting that “LSI” is NOT used by Google – largely because it doesn’t scale well.

(We did our own research and testing months ago to find out for sure. The more information you give it, the bigger, slower and less manageable the structure becomes. With the amount of information Google indexes, LSI doesn’t seem to be a logical solution.)

However, there’s also a HUGE amount of evidence proving that they at least use something similar – another way to work out common relationships between keywords, (as Stompernet also suggested recently.)

And there is a growing amount of evidence that suggests that LSI’d internal site structures, and the way pages are linked (from both within and beyond the site) “turbo-charge” search engine rankings. (Although this is something we won’t go into now.)

If you want to see LSI-style keyword relationships in practice, you don’t need to look far.

You only need to look at Adwords broad-match keyword matching, Google’s new Wonder Wheel, use the Google Synonym Tool, or watch some of the little-known Google Tech Talks where they show their internal related keyword generator being used, talk about how they developed it, and discuss organising information on the semantic web.

So even though “LSI” isn’t a technically correct term to describe the system that is being used, it’s still a de facto name for describing structured relationships between keywords. So if we say LSI, this is what we are referring to.
