what is LSI?

Hello,
Latent semantic analysis is a technique in natural language processing, in particular distributional semantics, of analyzing relationships between a set of documents and the terms they contain by producing a set of concepts related to the documents and terms.

LSI keywords are keywords similar to the primary keywords. On the contrary, it is believed that LSI keywords are NOT synonyms rather they just change on timely basis with the current trend.

LSI stands for latent semantic indexing.It is data retrieval technique.

Latent semantic indexing keywords, or LSI keywords is really just a dressed up name for synonyms or related keywords. LSI stands for Latent Semantic Indexing but let's not get complicated about this. In simple terms it is just how Google decides what your page is about. We all know about main keywords and anchor text links but these little guys are really important. Think about it, they are how Google decides what your page is about.

LSI stands for Latent Semantic Indexing it is an anti spam algorithm for detecting repeating synonyms of high paying keywords in the HTML body;if a keyword is overused in the website,Google will drop the website's rank,so all of the present day SEO service providers were using alternative words with the same meaning.
