Benefits of LSI for SEO

SEO has been the mantra of success for many a websites until now. The formula has been tried and tested and it has worked as well. The results were pretty much based on keyword density rather than the context in which the keyword has been used. Hence it was necessary to identify all the keywords which had the same meaning which a user might look for. For example, a user looking for ‘red kitchen cabinets’ might look for ‘kitchen cabinets red’ ‘red colored cabinets’ and many more such keyword variations all of which mean the same for him. But for the search engine spider they are all different keywords.

LSI

Now we have a new method of SEO called Latent Semantic Indexing. LSI is based on identifying a group of keywords and the context in which it is used in the text. It creates a much more natural approach to search engines and results rather than the more mechanical approach which was common until now. If you look closely at a search results page you will find at least three to four sites that are loaded with keywords but do not have any relevant content in it. This can be avoided with LSI. Apart from the specific keyword, users will also find those sites which have relevant information.

The benefits

Now when you do an LSI based search on music, you will not only have the results with the word music. You can also find radio, mp3 and stuff like that. It incorporates methods like Single Variable decomposition and creating a database of relevant keywords. Also common stop words are eliminated. These new results based on recall, precision and ranking has surely revolutionized the way search engines function. It also means that a web developer has to make sure that each and every word on a page is important and not just the keywords.
