Watercooler’s Justin Smith lists (at InsideFacebook) CPMs and eCPMs that Facebook app developers are collecting through ad-sales partners such as Social Media, VideoEgg, Lookery, AdSense and others. Most of those interviewed report CPMs between $0.04 and $0.60, with a few above a $1.00.

FM sells advertising and sponsorships on a few Facebook applications, including Watercooler and Graffiti, with CPMs in the $6-12 range. Though it’s important to note, we currently monetize only a minority of the ad inventory on those applications; we partner with several of the ad networks listed in Justin’s post to backfill the remainder.
