Web Site Marketing Strategy - Latent Semantic Indexing

Incorporating LSI Into Your Web Site Marketing Strategies

By

Guide Note: Many mathematical scholars disagree that latent semantic indexing is being used on any significant basis by any search engine. See the Article Update - Dissenting Opinion section that has been appended to this article since it first appeared on About Home Business.

If you want your website to be a success, your website marketing strategies must keep up with the changes made by various search engines. Search engine marketing is constantly evolving, and Webmasters need to evolve with it.

One of the most recent search engine marketing changes that must be addressed and incorporated into your website marketing strategies for increased website traffic involves Latent Semantic Indexing, also known as LSI.

What is LSI?

Patented in 1988, LSI was first incorporated into Google's ranking system in 2006. The LSI concept is groundbreaking for search engine marketing and website marketing strategies because it changes the way a search engine interprets and ranks web pages.

With the old ranking system, relevant pages were determined by keywords and keyword phrases alone. If the search engine didn't find any keywords, the page was considered irrelevant to the user, and ranked accordingly.

This left many webmasters scrambling to jam their pages with keywords for increased Web site traffic. These website marketing strategies left something to be desired, and were unfair to Webmasters who had good, relevant content.

With the new search engine algorithm, which incorporates LSI, such black hat search engine marketing and website marketing strategies will no longer work. LSI actually allows the search engine to examine a web page as a whole, looking for not only keywords, but also for words that are semantically close to keywords and keyword phrases.

Changing Your Website Marketing Strategies

LSI significantly changes the way webmasters need to use search engine marketing for increased website traffic, because the search engine will be looking at a page in the same way a human does—concentrating on content and relevancy, and essentially classifying the Web page as a whole.

For webmasters who use website marketing strategies that rely heavily on pages that incorporate only one keyword or keyword phrase, and do not include other content that is semantically close and relevant, this could be a problem, and may result in decreased web traffic rather than increased website traffic.

Webmasters, who on the other hand, have developed web pages and website marketing strategies that rely on natural content that incorporates both keywords and keyword alternatives, should have no problem. They will see increased Web site traffic without having to change their search engine marketing techniques.

If you are wondering how you can implement website marketing strategies that achieve increased traffic and are more compatible with LSI, you should focus on creating quality content that includes keywords, keyword alternatives, and mixed anchor text. Including variation and words that relate to the general theme of the page will be the best technique you can employ now that the rules of search engine marketing have changed.

The key is to move forward and not get frustrated with the change. LSI is a positive step for search engines and webmasters alike. By gearing your website marketing strategies to compliment the changes, you can create a better Web site and get the increased website traffic you need to be a success.

Article Update - A Dissenting Opinion on LSI

Since this article was first published, I received the following comment from Michael Duz:

[blockquote shade=Y]Contrary to popular belief latent semantic indexing (LSI) is not used by Google or any other search engine for that matter. This is for very good reasons, not least because the technique is extremely inefficient when applied to inhomogeneous datasets such as a large collection of web pages.

Information Retrieval research scientists have just about managed to perform LSI on approximately 0.01% of the Web but the academic jury is still out on the usefulness of the results.
