For example, deep linking to many pages within a website using anchor text that relates to the “theme” of the page is much more crucial than having a bunch of links back to your homepage. Anchor text keywords must also be thematically altered for inbound links to any one page. If this sounds confusing let me try and clear this shit up. Lets say the page you are linking to is about the “flu.” Right off the bat, LSI would determine if the phrase “naturally” occurs within the domain name [ie. www.fluhelp.com]. Next, LSI would look for some variations of related key phrases that could/should be used within the anchor text of the links:

“stomach flu”
“flu symptoms”
“bird flu”
“common cold”
“flu treatments”
“flu vaccine”
etc…

This is not a new practice by any means. Any real, decent SEO has probably been using themed strategies to achieve top rankings for years as the natural theming builds much stronger rankings and content. Most people who are new to the game think these new techniques have derived from the introduction of LSI technology when in fact “themed websites” have just been a closely guarded secret.
