based on my experiences with my domains, google updates the pagerank each month! but many friends believe that just minor update. on 30 June 2010 major update was occured, according me.
A lot of people have said that they did see changes in the past week so I think it might have already happened. Mine was updated back in June--from n/a to 0.
Hi, I think the coming update would happen at the end of the month. Keeping building quality backlinks for your pages would be better than only waiting. Have a nice day,
Actually Pr Updation can not be announced with confirmation, it can be just predict. and after analyzing the previous pr updation of the Google, it can be said that, it will happened in July sure, but the timing is also awaited, coz it is not officially declared by the Google. So only assumptions you can get.
You can't be sure they will update in July unless they themselves said they would. Did they? {I think they already did update the beginning of July, but it's up to them if and when they do again.}
PR update already happened couple of weeks ago, not a lot of sites showed difference though. This site: http://forumpromotion.net/forum/index.php I noticed went from PR2 to PR4 couple of weeks ago. Thats one proof for me that PR update is over.
