Latent Semantic Indexing (LSI): What it is, how it works and what it means

By Michael Marshall

LSI is a methodology for automatic document classification. It examines all the words in all the documents of a corpus and calculates similarity measurements for each document or for individual terms. 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. Measuring relevancy is a key component of a search engine’s ranking algorithm. When search engines use it, LSI can have a significant impact on the ranking of your web pages.

By Andy Beal

But, when you sit down and look at your search marketing campaign – the hundreds of keywords you spent hours researching on Wordtracker – do you ever wish you could get a jump on your competition and take a peek at what products will be the most searched over the coming months?

Well you could be like Napoleon Dynamite and strap an electrified cap to your head, or you could simply (and less painfully) plug yourself into the blogging community and get a glimpse of what keywords might soon show up in a keyword database.
