Analysis: How often brands post to Facebook, and the impressions they generate « Ignite Social Media: "top 5 posting pages are getting 32 times the number of impressions that the bottom 5 are getting. MTV generated an estimated 1.3 billion impressions from their effort, while Ferrero Rocher generated an estimated 2.1 million impressions because of their lack of effort on Facebook.
If part of the reason to market to is to generate positive impressions of your brand, this is not a number to be ignored. And if it were a traditional advertising share of voice calculation, the bottom five would try to increase their ad spend."
