New Patent for a Google PageRank Methodology
December 18, 2015
Google recently acquired a patent for a different approach to page ranking, we learn from “Recalculating PageRank” at SEO by the Sea. Though the patent was just granted, the application was submitted back in 2006. Writer Bill Slawski informs us:
“Under this new patent, Google adds a diversified set of trusted pages to act as seed sites. When calculating rankings for pages. Google would calculate a distance from the seed pages to the pages being ranked. A use of a trusted set of seed sites may sound a little like the TrustRank approach developed by Stanford and Yahoo a few years ago as described in Combating Web Spam with TrustRank (pdf). I don’t know what role, if any, the Yahoo paper had on the development of the approach in this patent application, but there seems to be some similarities. The new patent is: Producing a ranking for pages using distances in a Web-link graph.”
The theory behind trusted pages is that “good pages seldom point to bad ones.” The patent’s inventor, Nissan Hajaj, has been a Google senior engineer since 2004. See the write-up for the text of the patent, or navigate straight to the U.S. Patent and Trademark Office’s entry on the subject.
