If you’re a mobile app developer looking for a consistent, reliable way to monetize your work, Facebook might have an answer. According to a recent post on the company’s developer site, Facebook is testing a new mobile ad network for free apps which could be hugely beneficial to both advertisers and publishers. Facebook’s Sriram Krishnan says that the company is currently “running a small test to explore showing Facebook ads in third-party mobile apps.” If the test is successful and the team decides to fully implement the network, those targeted advertisements on your Facebook news feed could soon start appearing every time you open an app. For now the test is “limited to a few advertisers and partners,” but Facebook plans to expand the program in the future following successful testing.
