Since Facebook released their new updated version of Facebook Fan Pages that includes the ability to create custom iFrame tabs out of standard HTML code, people have been wondering about running Google Adsense within these apps.
However, the simple answer is that Google does not allow third party advertising applications to run on top of the Facebook platform.
You will not directly or indirectly transfer any data you receive from us, including user data or Facebook User IDs, to (or use such data in connection with) any ad network, ad exchange, data broker, or other advertising or monetization related toolset, even if a user consents to such transfer or use. By indirectly we mean you cannot, for example, transfer data to a third party who then transfers the data to an ad network. By any data we mean all data obtained through use of the Facebook API, including aggregate, anonymous or derivative data.
This “transferring of data” for the purposes of an ad network is a violation and could result in your application, and your profile, being removed from Facebook.
