Partner categories are targeting clusters created by facebook's 3rd party data providers including Acxiom, Datalogix, and Epsilon. Advertisers will be able to use these targeting options to identify and reach the right people on Facebook, based on their activity off Facebook.
Partner Categories can be found within the 'Who do you want your adverts to reach?' section of all our Create Flows.
Use the "Target partner categories" field to search and then select the relevant category.
Please note: Partner categories as a targeting option is only available in some markets
