"Mobile Sponsored Stories are getting over 13 times the click-through rates and earn 11.2 times the money per impression (eCPM) on mobile compared to all of Facebook’s desktop ads, and 1.93 times the CTR and 2.65 times the eCPM of Sponsored Stories on the web in the two weeks since Facebook began selling them separate from web ads"
If that's true and the ROI is also there, this will be useful to some.
If it's BS and "fat finger clicking", I expect we'll hear it from our mobile affiliates
