Many people are confused by search engine optimization and LSI. What is LSI and what has it to do with SEO? In fact nothing. Thats right nothing. Zilch. Absolutely nothing whatsoever. So why all the fuss? Through ignorance and possible subterfuge.
Latent Semantic Analysis (LSA) and Search Engines (SEO)
Latent Semantic Analysis (LSA) is applied by taking millions of web pages, where the search engines can learn which words are related and which noun concepts relate to one another. Searh Engines are considering related terms and recognizing which terms that frequently occur together, maybe on the same page, or in close enough proximity. So it is mainly used for language modeling or most other applications.
