The Changing Face of Search Engine Optimization

Google´s tilt towards the semantic indexing of Web pages and establishing relevance through this brilliant statistical method may have been the influence of Applied Semantics, the company known as the innovator of the semantic text processing technology. Google, in an aggressive move which spelled growth and astonished onlookers, took over Applied Semantics in April 2003. The acquisition had several interesting pros and cons and shook the SEO fraternity with expectations and skepticism.

The Latent Semantic Indexing (LSI), because it focuses on a bunch of keywords, so to say, and not a single keyword, and through its studied pattern of the relationship between semantically close and distant words in a collection of documents, it do not get confused between singular and plurals, or synonyms. It simply goes on to find the context developed by a bunch of keywords. So that, when you search for Tiger Woods, it doesn't go on to look for Web pages that has used the keywords “tiger' and ‘woods' but lists a collection of pages that discusses Golf. This is what is called relevance feedback.
