Big news from Facebook, analytics fans -- Insights is now improved with more Facebook-ishness. Ok, ok, no such noun, adjective, or verb. But it is improved.
With anticipation of expanded usage, Facebook now allows Insight administrators to measure social plug in usage -- the plug ins being the well-known "Like" and "Share" Facebook buttons. Facebook also revised the dashboard for more drill-down capability into data and graphs.
For those who have never heard of Insight -- it is a Facebook analytics tool designed to measure engagement of 3 major sets of Facebook services; Facebook Applications, Facebook Fanpages, and Facebook Ads (You can read more about how to use these Facebook services at the AllBusiness.com article I wrote). With Facebook's popularity among internet users (and marketers), it would be inevitable that an analytics solution would be created.
