LSI: Latent Semantic Indexing

LSI is all about relevance and this couldn't be more relevant to what we try to achieve with our blogsites.

I've said it many times - write about your business; stay on message; concentrate on communicating with new and existing customers, and your visibility on the Internet will increase. The idea here is to create a cloud where new customers may find you based on search queries that you did not (and cannot) predict with any accuracy.

This is a model that runs in the face of many things we believe to be true about search engine optimization. Predicting what people will type when searching for you is a difficult proposition because it's a process that doesn't factor in problems that people have, and what they look for to solve those problems.

To me, going after a narrow set of very specific keywords is risky - it puts your SEO strategy in one basket. Wouldn't it make sense to allow your own writing define the key-terms and phrases in a context that supports the likely problem domains that your target audience experiences?

Along comes LSI (Latent Semantic Indexing) and all of sudden, keywords are de-emphasized. Not only are they de-emphasized, the keywords used to find a particular post don't even have to be in the blog post!

If we can assume that search engines are leaning toward LSI implementations (and it seems they already have), it places the burdon of discoverability on specific ideas and thoughts expressed in a context that is meaningful and clear. The latest indexing shake-up in Google may be an indication of things to come.

"Latent semantic indexing helps search engines to find out what a web page is all about." -- Axandra Newsletter

If this is true, a blog will be more likely to be found if it is focused; about one topic. A blog post will be more likely to be found if it is about one thing and closely in context with the blog.
