Hi all,I am waiting for the google page rank updation.So I need to know , when will be the next google page rank updation.I think the last google page rank updation was october 22 nd 2005.Also I need to some facts about this.. like duration between page rank updation and all etc..I believe they happen on average every 4 months (give or take).Someone posted a big list of all the dates of PR updates, If i find it i'll come back and post it.Do Google update their backlinks to sites with the PR update or is that on another schedule?I believe a backlink update happens shortly before a PR update.hi all, any idea? when is the next PR update?nobody knows when google are going to do it, they happen on average every 4 monthsPR is worthless though. Don't worry about it.
