Google Now Indexes 620 Million Facebook Groups

Last October we reported that Google was indexing over 52 million Facebook groups. Only three months that number has surged to over 620 million, out of an approximate 1.96 billion pages across all of Facebook. The total number of groups on Facebook is now approximately the same number of pages Google indexes of eBay. So how accurate are these numbers? Pretty rough, but they are decent approximations.

With 620 million groups on Facebook, the average user creates just under 2 Facebook groups. Obviously this is simply the mean and not the median, which would more accurately reflect Facebook Group usage. We would expect a small percentage of Facebook users to make up the majority of group usage. Every user I know is at least a member of one group however, as it’s an integral component of the Facebook experience.
