Actual Time - Google Update

I want to Information about Google Update

Which time duration Google Updating service ?

 

When the melons turn green and the owl hoots to the silvery moon.

 

Actually every 3 to 4 months once google updation, but from last 3 months i saw every month done google updation.

 

May be this month google updation is on last week.

 

about 3 months google updates...

 

it seems google is very imprevisible in the recent months so no one can guess

 

Between 2 to 4 months Google is updated itself.

 

i have already seen one or other update from my backlinks, my keywords ranking, serp everything change after 20 - 40 days, so google update always on

 

It use to be a regular 3 months but it has been a little hit and miss of late.

 

Google updating every 2-3 months. last month middly G updates. So next will be dec or jan midddle

 

It depends on the service gets updated, how ever no body know for sure except for Google
