Peter Da Vanzo makes assertions about ranking factors in Google's search engine results pages based on a patent unearthed by Bill Slawski over at SEO By the Sea. The patent, Ranking Documents, describes how changes to a page by a webmaster may cause Google's technology to initially shift ranking, randomly, before settling on a specific order. Da Vanzo tells us the problems associated with this process and digs into Google's definition of "spammers."
