I put this video together on how PageRank works last year whilst practising it for Pubcon in Las Vegas. I will also talk on PageRank at BrightonSEO in September. The presentation takes what looks to be a very complicated mathematical algorithm and break it down into concepts that mortals with basic Excel knowledge can understand.
Is PageRank still used today?
This is a common question. Larry Page came up with the concept and with the help of Sergei Brin, it became the cornerstone of Google’s early success. Googlers say it is still used, according to this video. On the other hand, a recent article by Roger Monti suggests that it may have been shelved in 2006. Now – this is from an ex-Googler, so it does seem odd that Gary Illyes made it
So what gives?
The truth of the matter is that Google may have
The Power method is another iterative in a way that can change the PageRank of an individual page at a time. These methods resulted in what we SEOs used to call the “Google Dance”. Periodically, Google will have recalculated PageRank for every URL and the Search Engine Results Pages (SERPs) used to bounce around for a few days, whilst all the indices were updated.
When the Google Dance stopped (which probably was around 2006 if my memory serves me correctly), Google will have found a way to calculate or approximate PageRank on the fly. This lecture from Stanford University looks at some ideas such as the Random Surfer Model, which considers Pagerank from the point of view of the probability that the person was on the page one click after their last page visit.
Perhaps this is what I should demonstrate at Brighton?
