LSI is Latent Semantic Indexing.
This system is already being used in some forms by Google and is something that will become ever more important in its algorithm once the technology is advanced enough to use it. Sites that use LSI (and are coincidentally dominating search results…) include ESPN.com and Wikipedia.
The Latent Semantic Indexing system will hopefully take SEO to a different level by using a database system that will select certain keywords to link with one another. For example a keyword like “SEO” will be commonly found with words like search engine, ranking, website, services, internet marketing etc.
E.g. SEO –> Search Engine
This LSI technology will then measure page strength by the amount of related words that are in the content or on the page for your selected keyword. E.g. a site may rank higher in the SERP’s if its pages contain the correct related keyword(s). This means that each of your keywords will have their own “magic words” that you should add to optimise your site properly.
If you are looking to find the “magic words” for your keyword then check out Quintura. On Quintura you can type in your specific keyword and the system will show the related words that feature on other websites. Make sense? If not go an have a look for yourself.
So next time you are writing an article or post look up your related keywords and make sure you add them into the content. Obviously if you want to take this to an even higher level you can also add related words that are connected to your “magic words”
E.g. SEO –> Search Engine –> Services
This way you can link with relevant pages making your original page even more relevant to Google. Will LSI be a huge factor in future algorithms? Is it already? Either way it should help us in writing better content and improving our ranking results.
