To create a custom audience within an Ad Set, follow these steps:
- Navigate to the Custom Audience section.
- Click Upload New Audience and a new modal will appear.
In the modal, you can:
- Enter an Audience Name in the text field along with a Description
- Upload a file in .csv and .txt format. If you're uploading a new audience for the first time, you must accept Universal Ad’s Custom Audience Matching Terms. You only need to complete this step once.
- Drag and drop your customer list file into the upload area or select the file manually. Alternatively, you can copy and paste the values directly onto the upload page.
Note: for a successful upload, please ensure your file has 1,000 valid unique records that follow the formatting rule of one record per row and no headers.
