Google Latent Semantic Indexing (LSI) Technology

The recent changes at Google SERPs have brought a focus on LSI: Latent Semantic Indexing among the many seo professionals and business owners. It is an approach to understanding keywords in the context of the words on the entire webpage.

In addition to relying on keywords on a web page, Google now applies LSI technology to identify the words that has relevancy to one another. For example, LSI can discover relevancy between the words ‘Iraq’, ‘George Bush’ and ‘Saddam Hussein’ for the search term ‘iraq war’.

For LSI, Context is the King. Next time, when you optimize a page, make sure that you focus on relevancy and context.
