Facebook recently announced that small businesses now have access to analytics which allow them to see per-post impressions and feedback for posted stories.  Previously, this capability was restrcited to pages with over 10,000 fans or more.

Clearly, Facebook wants a larger piece of the SMB pie, an area that as of now has been the domain of Google.  Chalk this up as another "shot across the bow" in the looming battle between these giants.  The best thing is - you benefit as a result, and improving the insight into your business is critical if your goal is to thrive in a highly competitive, fragmented market segment.
