Looks like finally Google has rolled out the second Page Rank update for the year of 2013. This is a major update and I see a lot of fluctuations. Many sites have dropped their page rank in this update and some have boosted up.
If you don't know Page Rank is one of the major Google Algorithm which
varies from 0 to 10 based upon the number of backlink's a site has.
Higher the better.
Page Rank has lost its importance with time. I can clearly see the page
rank algorithm has changed to a certain extent this time.
