Remember PageRank?
PageRank named after Larry Page, is Google's link analysis algorithm. This is an exam which Google conducts for all websites around the world and each gets a mark. The marks range from 0 to 10.
Google conducts this exam periodically and changes the marks for each website considering more than 500 million variables and 2 billion terms.
As on October 2011, Facebook was well ahead of Google+ by 2 points in terms of page rank. But it looks like the gap has been narrowed.
Google+ Page Rank.
Facebook Page Rank.
Google+ had an unbelievable rally growing to 150 million users in just 6 months. That along with December 2011 seeing a doubling in traffic, an increase in Google+ page rank should have made more sense... Well, Google knows better!!!
