how often google update pagerank of websites... on daily basis or once in month twice in month or once in 3 months can anyone please guide...
Generally once in 3 months.. but last time the update took 4 months The recent 4 pR updates Dec 31 2008 then April 1 2009 then june 31 2009 oct 30 2009
There is no certain date that they update it. Nd you should know PR no longer affects ur ranking in serps.
You cant tell the date like dis .,,!! no one can predict the date.. Even months cannot be predicted... only Google knows these things.. Build Backlinks and add unique contents google will take care of the rest of the things.!!
Previously Google is updating once in three months period Now Google is not telling the updating dates because everyone is alerting at that period to get more PR.
Some people believe that the PR changes all the time on the back end: and that the visible PR [the PR that users can see], only updates after 3-4 months.
Goolge just updated the PR on the late of October, you might expect the change on next year, but no one know the exact date, anyway you can shot a email to Matt Cutt.
the PR is updated frequently but just hidden in the eyes of normal people. However it will only show itself one time during the major toolbar PR update.
To be frank, we do not know the period. Mostly it will be in 3 months. Some times it will be updated soon, some times late. Not sure what is going on inside G...!
Im think it is daily or weekly that they update pr. Because my website keeps changing positions every day
