Facebook is making significantly more money per ad now, charging 23% more per 1000 impressions than at the start of 2011.
Still, ads pointing inside Facebook cost 29% less, and ads that specifically ask users to become a fan of a Page cost 45% less than those linking anywhere else. Why is Facebook offering this incentive? Because internally pointed ads keep users on the site where they can continue to be exposed to ads.
Moreover, Sponsored stories are getting a 46% higher CTR, which is a win-win situation both for investors and Facebook itself.
Where is all this going? If prices keep rising, we’ll see which new advertising markets investors will invade. Twitter, for instance.
