Facebook Mobile Ads Outperform Desktop, Twitter

Average CPM jumped 58 percent since Q2 2011, per TBG Digital

Update: TBG Digital has clarified the Facebook/Twitter comparison. “We took a deeper look at the data and, unfortunately, the engagement rates were not comparing like for like. Twitter engagement rate measured click-through pate on Promoted Accounts whereas the Facebook CTR was for Newsfeed ads. A more comparable product for Twitter would have been Promoted Tweets, which typically see 1-3 percent engagement rates on desktop and even higher on mobile,” the company wrote on Friday in a post to its site.
