Recently, I read an interesting blog post by Barry Adams titled “The Adversarial Relationship between Google and SEO“. He argues that Google’s not an SEO’s friend but rather an adversary and cited quite an interesting patent filing by Google titled ‘Ranking Documents’. If you’re an SEO I’d strongly suggest you take the time to read this document in full. Also, Bill Slawski provides an excellent analysis of how this
new approach will affect a page’s rankings.
In layman’s terms, this patent document specifies how Google intends on making rank changes to its search engine results pages (SERPs). Instead of allowing the algorithm to use its ranking factors to decide how documents (or pages) are ranked, Google will randomly initiate a “transition” period between when a rank change happens.
