Facebook will cut off access to third party data for ad targeting

In a surprise change, Facebook will give up one major data source that the company uses to help advertisers target relevant users on the platform. The company just announced that it will end a feature called Partner Categories, launched back in 2013 out of a partnership between Facebook and major data brokers.

Third party data helps Facebook further atomize its user base into meaningful segments for advertisers. As TechCrunch explained when the data partnership first launched:

“Through new partnerships with top online and offline purchase data providers Datalogix, Epsilon, Acxiom, and BlueKai, Facebook is now allowing advertisers to target hashed lists of existing and potential customers, and categories like role-playing gamers or soda drinkers.”

Facebook confirmed to TechCrunch that the change is permanent, not a temporary precaution. In order to leverage the deep pool of data Facebook collects on users, the company mixes information that it obtains from users themselves (Pages a user liked, for instance) with information from advertisers (membership status in a loyalty program, for example) and with data obtained from third party providers.

While Facebook feels comfortable with the integrity of its data sourcing within the first two categories, it feels less settled about dipping into these aggregate pools of third party data. The decision was issued in light of the company’s recent privacy concerns over third-party data mishandling.

Facebook Product Marketing Director Graham Mudd elaborated on the decision in a statement:

“We want to let advertisers know that we will be shutting down Partner Categories. This product enables third party data providers to offer their targeting directly on Facebook. While this is common industry practice, we believe this step, winding down over the next six months, will help improve people’s privacy on Facebook.”

Facebook clarified that it will still work with companies like Experian and Acxiom in order to measure ad performance and provide metrics, although it will also be conducting a review of those ongoing relationships. Facebook may also move toward sharing data in a shared server environment in order to offer further assurances of user privacy. As Mudd noted, the program will be discontinued in the coming months.
