By now, most of us already know that Google page rank (PR) update takes place every 3-4 months once. I am not a big fan of page rank but it is still a good measurement to calculate number of quality backlink a site or page received. Pagerank is still one of the measurement factor in setting advertising value for a website or blog. Most advertisers still prefer to get a dofollow backlink from high PR relevant quality sites. Although, Google don’t allow us to sell or buy links with dofollow which may lead to penalties, there are still many bloggers and webmasters sells links that passes PR juice. Most advertisers believe that nofollow tag added link have no value at all.
Anyway, it is truly depend on the advertiser and webmaster to sell or buy dofollow links. Penalties from Google can lead to pagerank drop or pagerank removal completely regardless of 3-4 months period. It won’t take 3 or 4 months for Google to give penalty to site. This means page rank update will take place for 3 to 4 times a year. If your site drops in pagerank not during the major pagerank update means your site might get some sort of Google penalty. Let’s talk about the history of pagerank prediction. For last two years, Google updated pagerank widely to most website and blogs online just before New Year. I suggest you to follow link building strategies before building high PR links.
I have noticed that twice, once by end of 2008 and the other end of 2009. So, my guess will be the same for 2010 too. I have seen four updates taken place in year 2008 and 2009. I assume there will be four updates in 2010 too. Since, last update done before New Year that is 31st December 2009, next pagerank update most probably will take place by 31st March 2010. If Google follow that 4 months once update, then the next pagerank update will take place by 30th April 2010. The reading of following pagerank update will be adding another 90 to 120 days from March or April 2010. The same cycle goes for every pagerank update. Below is the next page rank update prediction for year 2010.
First Page Rank Update: 31st March 2010 – 30th April 2010
Second Page Rank Update: 30th June 2010 – 31st July 2010
Third Page Rank Update: 30th September 2010 – 31st October 2010
Fourth Page Rank Update: 31st December 2010
