Ok lets predict. The second to last update was on the first week of January. Mine was at least. The last update was on the first week of May. That is a 4 month difference. From this data I hypothesize that the next update will be in September of the first week. It usually takes every quarter (4 months is equal to a quarter) of the year to update. Sometimes 3 months.
try to list ur site in different directories and start link exchange as much as u can and if u have any high PR site try to put ur link on that page hope u r site will be index asap
if you mean pr update , it has been completed 3 weeks before. you have to wait 3 months for the next page rank update
Yep 3 months is the correct time. But in the last few month it comes a little bit later, don't know why. And it takes more then 2-3 days to get the pr upgrade done. Here is a tool where you can see what PR gives you every single data center : http://www.iwebtool.com/pagerank_checker - I think that most of you are familiar with it. Also i think that 3m. is the time, cuz the alexa rang has 3 months as average stat. meaning that this period of time is the minimum of knowing how much is your site popular on the net. Best Regards
it happens every 3 months.(about that) latest one was the end of April so predicted next PR will be End of July. BUT normally google will make a snapshot your your site and link about a month before that to generate the PR so I would recommend to build the back links to your site as much as you can before the end of June will give you the most benefit.
backlinks and PR are expected to update every three months. But sometimes backlinks update less than 3 months and update PR more than three months. We can't predict when would be the real next update of google.
