About Managing Custom Audiences
TikTok allows you to create Custom Audiences to find people who already know or have engaged with your business. You'll be able to add, edit, remove, or replace your custom audience data at any time.
Note: There is a required minimum audience size of 1,000 to target Custom Audiences in an ad group. One available audience can be applied to multiple Ad Groups (without overlapping the included and excluded audiences)
Once you have accessed the audiences page in TikTok Ads Manager, you can manage your custom audiences by:
Audience Application Details: Shows the relationship between the ad groups and audience.
Disconnect Ad Groups: Disconnects the ad groups which are applied to the audience.
Audience History: Shows the activity log for creating or editing audience data.
Through the customer file, you'll be able to:
Add Data: Upload a file you would like to add to your audience. Note: Only new data will be added.
Remove Data: Upload a file you would like to remove from your audience. Note: Only existing data will be removed.
Replace Data: Original audience data will be replaced after the upload of data file. The audience ID will not be changed.
Edit Audience Name: You can edit the audience name any time.
Custom Audience considerations
If you notice your Custom Audience is not available, please note:
It takes 24-28 hours for an uploaded list to be available for use as a Custom Audience.
You need at least 1,000 identifiers in the uploaded customer file matched with users on the platform in order to make the Customer Audience available.
Audiences that haven't been used for a long period will begin to expire. When audiences expire, their availability status becomes "unavailable" and the only option is to delete the audience from the library.
