I estimate August 16 th will be the next PageRank update. The next BL update should be at the end of July 2007 ,after that 7 th to the 16 th of August should be the time of the next TBPR (tool bar pagerank) update is complete. The “Buffy” name came from WebmasterWorld Admin explains:

Ever since Update Jagger, which prepared the way for Google’s new Big Daddy infrastructure, the changes and shifts to the SERPs come so frequently that we haven’t called an Update in over a year. Instead, we’ve been trying to watch the SERP changes in an ongoing, monthly thread that shifts with the irregular roll, pitch and yaw of the good ship Google.

The history of PR updates:

* April 27, 2007
* January 25, 2007
* January 10, 2007
* September 28, 2006
* July 13, 2006
* April 4, 2006
* February 18, 2006
* December 19, 2005
* October 19, 2005

Over the last two years Google has updated PageRank 10 times, on average once every three months.

PageRank is calculated using:

1. The number of pages linking to the page.
2. The PageRank of the pages linking to the page.
3. The number of links going out from the pages that are linking to the page.
