Latent Semantic Indexing - A Guide To Using Lsi In Getting Better Search Engine Results


The search engine roams the hyperlinks of the internet in search of web pages or websites that they are commanded to search for. The command is in form of keywords that are typed in by the visitors. Basically the use of algorithms is employed by the search engine to get the desired result. The page/site is indexed and ranked on the basis of frequency of queries posted by the surfers. Higher the frequency of queries for a particular site, higher the page ranking it gets.

What is Latent Semantic Indexing?

It popularly known as LSI is short form. It uses algorithms to convert the natural language into mathematical language that computer can easily understand. Semantics means study of meaning of words. Latent Semantic Index is about applying the supporting keywords that relate well with the main keyword. Suppose video game design is the main keyword, then game design, video design, video game become LSI keywords.

Using LSI Properly in the Content

To effectively optimize the web content to get higher ranking from the search engine, it is important to select the right keywords. The selected keyword should relate well with content. Taking help of the Google Keyword tool greatly helps in selecting the right keyword or the most probable keyword, for a particular site or content that one is looking for. In addition the tool provides the list of related keywords. These related keywords are called the LSI keywords and help in boosting the page rankings.

Importance of LSI in Article

The Latent Semantic Index system advocates use of several supporting keywords along with the main keyword in a content. This strategy provides the search engine more option or pathways to reach a particular site, rather following a restricted and narrow path that main keyword provides. This greatly increases the probability of more surfers hitting the site successfully. The supporting keywords here increase the visibility of the site or page on the net, manifolds. The Latent Semantic Index advocates use of more related keywords, instead of maintaining the keyword density of the main keyword. The keyword density does not hold value in this concept; rather it lays stress on maintaining high quality and relevant content that relates well with the keywords. This helps in providing better search engine results to the surfers, compared to what a single keyword based search, provides. This technique is being slowly integrated by the Google in its search engine system to boost further the speed of web access.
