If you've heard the phrase "latent semantic indexing" (LSI) but have no idea what it means or why it matters to you, you're not alone. There's been quite a bit of buzz over this concept within the search community, but most web site owners and small businesses are still in the dark about why it matters to them.

Search engines are always looking for ways to update their algorithms so that they more accurately reflect the results that a human being would want to see when typing in a search engine query. Latent semantic indexing is a type of technology that works to understand what a page is about. Read that a second time...to understand. Not just to index or to pick out a frequency of a certain word, but to actually read all of the words on a page and then put things into context.

The use of latent semantic indexing by search engines introduces an even stronger focus on why good copy writing skills are an essential part of any search marketing campaign.
