Is Latent Semantic Indexing - LSI - Necessary

I'd like to simplify LSI. Instead of linking in all of the scholarly papers from those whose job with Google is to fight spam and make search engine results better for you; I am going to give you the down and dirty truth of what LSI is and why it is important to not just Google but all Internet entrepreneurs.

Since you're reading about LSI and its is not a common term I am going to assume you are familiar with Google products such as Adwords, Adsense, their search engine, etc. Most people use proper semantics and synonymic words in their website content and do not have to worry about LSI.

Latent Semantic Indexing: means that when you do a search online for a particular word or phrase Google searches the net not only for that term but for terms used in conjunction with it "semantics". The aforementioned is designed to return quality content.

Rather than providing quality content some webmasters initially found that spam would get them quick cash. Adsense started to see an increase in "click fraud" which meant a portion of Advertisers' budgets was getting drained by spammers. Through LSI Google is on track to cut back on bogus websites and advertisers.

Google devoted resources to update the Googlebot algorithm to make a distinction between quality and a spammy website.

Google's Adwords and Adsence business model is great because when it works correctly everyone gets paid. If you do a search on "Alligator shoes " that is what you want information on. The search engine returns info you are satisfied with so you go to a website. From the website you click on a link to an eStore that sells the shoe and you make a purchase.

Easy as 1-2-3.

The Webmaster gets paid when you click on a link while on his/her website.

Google gets paid from the "Advertised site".

The Advertised site gets paid when you make a purchase.

LSI is here to ensure everyone gets what they want when using a search engine. This also makes the Internet business playing field more leveled. It is important that you start or rebuild your website with themed content using LSI rules (know "rules" have been published but I like the word).

Themed content: Stick with what your website is about. It is important that search engine robots do not get confused when they visit your website.

Spammy website: over indulgence in keywords or phrases will not come across as quality content.

LSI: use synonymic terms in your content.

An easy method to determine what content search engine robots consider quality do a search. The information returned on the right is what you should model (not plagiarize) your sites content after.

Following the best is a good practice.

LSI separates spammy websites from those of quality. LSI is not a myth. Organic search engine optimization is the cheapest way to achieving higher page rank.

Individuals that do not make or convert their website content within LSI standards will see a slow drop in their search engine ranking. Google and other search engines will continue deindexing sites that have no content of value.

Is LSI necessary? I would suggest ensuring your website content relevancy is accurate

Websites are a great way to supply the Internet with content of value. Find your niche and build your website right the first time.
