Audience sharing allows you to leverage audience data across different ad accounts for targeting in campaigns. You can share a Custom Audience (created from Engagement, App Activity, Website Traffic, Customer File, or Partner Audiences) and a Lookalike Audience to specified ad accounts within the same TikTok Business Center.
Note: Only allowlisted customers can share audiences between accounts outside of a single Business Center.
To share audiences:
Log in to TikTok Ads Manager.
Click on Tools.
Click on Audience.
Select the audience name and click on the 3-dot icon.
Click Share.
Enter the ad account ID of the recipient you want to share the audience with or select the recipient from the drop down menu.
Click Confirm.
