Facebook has created an entire economy of companies selling services built on its platform, those buyers of the services–advertisers mostly–have requested more clarity on the performance of their ads. As a result, the company has created a Preferred Marketing Developer which is basically a combination of it’s Preferred Developer Consultant (PDC) and Marketing API (MAP) programs. So that’s less confusing, we suppose. There are now 90 preferred developers (versus the 14 the program originally launched with), so it makes sense that marketers need a little more guidance on who to purchase services from.
