Analysis: How often brands post to Facebook, and the impressions they generate « Ignite Social Media: " if you know how many fans the post can potentially reach (all of them) and you know how many times fans like or comment on a post, you can multiply those fan actions by the average number of friends that each active fan has. It’s a bunch of math that Expion performs routinely.

Since no page gets all the impressions possibly, however, I multiplied the maximum impressions by the expected impressions. Facebook reports that 16% of fans see a given brand post and 12% of their friends’ posts. So calculating 14% of the maximum impressions gives us a rough estimate of the actual impressions per brand, factoring in the brand posts and the fan actions."
