I would like to simplify LSI. Instead of linking to all the academic articles from those whose job with Google is to fight spam and improve search engine results for you; I’m going to give you the dirty truth of what LSI is and why it matters not just to Google but to all internet entrepreneurs.
Since you are reading about LSI and it is not a common term, I will assume that you are familiar with Google products like Adwords, Adsense, their search engine, etc. Most people use proper semantics and synonyms in their website content and don’t have to worry about LSI.
Latent semantic indexing: This means that when you do an online search for a particular word or phrase, Google searches the web for not only that term, but also terms used along with their “semantics.” The above is designed to return quality content.
Instead of providing quality content, some webmasters initially discovered that spam would make them a quick buck. AdSense began to see an increase in “click fraud,” which meant that spammers were depleting a portion of advertisers’ budgets. Through LSI, Google is on its way to reducing fake websites and fake advertisers.
Google devoted resources to updating the Googlebot algorithm to distinguish between a quality website and spam.
Google’s AdWords and Adsence business model is fantastic because when it works properly, everyone gets paid. If you do a search on “crocodile shoes”, that’s what you want to find out about. The search engine returns information that it is happy with, so it goes to a website. From the website, you click on a link to an online store that sells the shoe and make a purchase.
Easy as 1-2-3.
The webmaster gets paid when he clicks on a link while on his website.
Google is paid from the “advertised site”.
The advertised site is paid when you make a purchase.
LSI is here to make sure everyone gets what they want when they use a search engine. This also makes the playing field for Internet business more level. It is important that you start or rebuild your website with thematic content using the LSI rules (I know “rules” have been published, but I like the word).
Thematic content: Stick to what your website is about. It is important that search engine robots do not get confused when they visit your website.
Fraudulent website: Excessive use of keywords or phrases will not be considered quality content.
LSI: use synonymous terms in your content.
A simple method to determine what content search engine robots consider quality when performing a search. The information returned to the right is what you should model (not plagiarize) after your sites content.
Following the best is a good practice.
LSI separates spammy websites from quality ones. LSI is not a myth. Organic search engine optimization is the cheapest way to achieve a higher page rank.
People who do not create or convert their website content within LSI standards will see a slow drop in their search engine rankings. Google and other search engines will continue to de-index sites that have no content of value.
Is LSI necessary? I would suggest making sure the relevancy of your website content is accurate.
Websites are a great way to provide valuable content to the Internet. Find your niche and build your website right the first time.
