What is LSI?
LSI, also known as a Latent Semantic Indexing, is a method based on determining relationship and relevance of the content of web page to the keywords and terms being searched out. This mathematical method is used by search engines in order to reduce spam websites. Contents are crawled and the most common words are defined as a web page’s keywords. More synonyms in the content lead to placing a greater importance on the web page by the search engine.
