About Custom Audience relationships

Before you share your audiences with other entities, it's important to understand what these relationships mean. You must first connect the two Business Manager accounts before an audience can be shared to another ad account. Both your account and the account you're sharing audiences with are required to affirm compliance with our Custom Audiences Terms.

Next, business partner's audiences (such as agencies, data managers, or marketing partners) can either be shared to an ad account or uploaded directly into an ad account.
