Senh: Zynga makes up 19% of Facebook's revenue for 2011: “Please disclose that revenue from ads shown to users using Zynga apps on Facebook was approximately 7% of your revenue for 2011,” reads the April 10 letter from SEC Assistant Director Barbara Jacobs to Facebook CFO David Ebersman, “and that this is in addition to the 12% of your 2011 revenue derived from payments processing fees related to Zynga’s sale of virtual goods and direct advertising purchased by Zynga.”
In light of Facebook’s disappointing IPO, I'll pull up an article I wrote in February, which said, “... social networks have always been poor at monetizing their traffic, and that hasn’t changed since they gain popularity. Click-thru rates for ads on social networks have always been really low, so they can’t charge nearly as much as Google per pageview. That hasn’t changed since social networks entered the internet landscape and won’t change in the future.”
