Buoyant Page Rank
Please see the archived video on Buoyant Page Rank and its relationship to Website Silo Architecture.
Buoyant Page Rank is a neologism used by Theme Zoom Co-Inventor Russell Wright. It is used to describe the effects of deep linking within a Website Silo Architecture model of SEO. If inbound links with similar themes or synonymic meaning are pointed deep within the articles of a website, the Google page rank may have a "buoyant" effect on the Silo Landing Pages that are targetted for ranking on the search engine. Most SEO professionals tend to target the Silo Landing Page instead of deeper and less prominant pages within the site. It is better to also target deep pages. This can be accomplished using technologies such as the Wordpress SEO Silo Plugin, among others.
