Facebook is currently beta testing a feature that lets advertisers target users (or friends of users) who performed a specific Open Graph action via a specific application. Together with smart CPM pricing tactics, that’s a game changer for app developers. Remember where you read it for the first time.
Users can now be targeted based on their use of the app. In this example we can target FB users who viewed a video on the app with app ID 1234567.
Again, unless you are a FB partner, preferred developer or have access to one – you’ll have to wait a bit.

Facebook is beta testing a targeting feature – called “Action Spec Targeting” — for our interested Ads API partners. The new feature is designed to help advertisers target users based on actions they have performed. Because this feature is still in beta, we expect it to change. Please keep that in mind as you test this new feature in your campaigns and tools.
Action specs are used to describe actions people have taken on Open Graph objects via an application or on on-Facebook objects directly. Action Specs can be used to target Ads at users or friends of users who have performed a specific action, e.g. target an ad group at users who listened to music on a specific app or commented on a page post. Please review the the action spec documentation for more details on how action specs are defined.
Note: It is not possible to target a ‘like’ of a Facebook page via action specs. Note: Action specs are limited to be a maximum of 4096 characters in length.
