Google PR - How often does it update

Just wondering - how often does google Page rank update ?

I have a couple sites some i hope will update and other i know wont be updating.

so is there like a set time - once a week, month . . .

any help on this matter would be appreatiated.

Thx in advance
rep to be given out on the matter

 

4 times a year, so around once per 3 months

 

Please please please..... NO more PR threads!

 

Ha ha ha as Malcolm1 has already said, No more threads on google's pr update.

And as giamatti has said, yes, its 4 times a year. But, do not consider this all time update as G's PRing year calendar varies from general calendars.

All that matters is, quality content and good backlinks.

 

It updates around every 3-4 months

 

4 major updates and several minor ones every year

 

I think.. google updates 1 - 2 times a month (minor updates).

 

Four times a year, updates are being done every 3-4 months There are tons of PR update threads here in DP, just search around.

 

Minimum 4 huge update, and some little dance updating

 

Four times in a year ... around once in every three months. But however Google keep updating minor one now and than.

Last major PR done on December 31st ... so according to that PR is going to happen in coming 20 - 25 days.

Its result time mates.

 

All of these are just prediction. Nowadays, it happens on around 3 months once, but I remember few years ago when it took 6 months for Google to update PR.

 

Every three months google will update its page rank!!
