We know that everyone has questions on the new Insights metrics like Reach and People Talking About This. Here's our take:
Towards the beginning of 2012, Facebook has been making major changes to Insights and keeps getting behind in processing everything. Normally, you should expect around a 48 hour delay.
Instead of updating only our awesome customers, we figured we'd give everyone a simple site to see how far behind you should be. :)
We're the folks bringing you this nifty little site. We provide better Facebook Analytics than you ever thought possible.
Four of the top ten largest Pages use PageLever to measure how effective their efforts are on Facebook.
