How LSI is different from conventional SEO?

Latent semantic indexing is a way to create Web content that will be indexed by search engines and is optimized for the best possible positioning in search results. Put simply LSI gives the search engines the ability to provide its users a more relevant list of options to choose from
Search engine optimization techniques, it seeks to use search engine indexing technology to achieve a better search engine position. From last decade, things have changed dramatically. We are suffering from information overload. LSI statistical probability and trying and work out the semantic between words and/or phrases in relation to a know topic.
Search engine organizations implementing LSI are not only studying a web page for keywords as in conventional SEO , they are also studying your site pages and learning to recognize and identify the words that are related to each other in web site. By using this technique, the search engine databases are indexing the 'semantic relationship' between your website pages to discover which pages are 'related' to an overall theme.
One big question comes in mind that how LSI works? How can we increase index performance of web site with use of this LSI technique? The answer is that LSI scans all the website pages and takes on step further by analyzing the complete website that the page is a part of as well.
LSI is introduced to get better search experience (to avoid spamming) to users if they search for a particular or specific term on the search engine. They don't want to waste their time. When you put these factors together the logical assumption should be that search engines need a human touch to make them better.
Many spammers though up more and more ways to fool the search engines and 'catch' the unsuspecting internet user, so the user has become more adept at 'spotting spammy sites'.

Latent semantic indexing analyzing all web pages before it gets indexed. LSI optimizing pages more effectively and point towards content that may be relevant within the document. It is just like automated grading system .It is the technology that has the power to filter website pages to show unwanted information. This technology is improving day to day and will be more effective in future.
