A Snippet:

"Latent Semantic Indexing (LSI) is a highly beneficial technique for search engines to use for improving recall, precision, and ranking. It can gauge very accurately which documents in a corpus are really relevant to a search phrase even if that search phrase does not appear in a document."

Bravo! Get Mr. Marshall to write more articles!

What this means for the search engine optimization (SEO) specialist and anyone with a website who wants high visibility in the search engines is that every word on your web page is important, not just the keyphrase(s). It is the right combination of all the words in your content that really matters here. What you do with your keyphrase(s) is still important but now you must go beyond that . . . way beyond that. You’ve got to have the right context to support your keyphrase(s).

Outstanding! Maybe with these types of analyses and increased awareness of this type of thinking we can put the kibosh on scraper sites and bad sites that play the engines for ranking.

Very well-written and extremely informative. Thanks for that!

Nice article.

Though I'm not quite sure what Michael was trying to tell us with the Augustine part, I still enjoyed the attempt to use alternative ways to think about, and view this type of indexing.
