A custom audience is an ad targeting option that lets you find your existing audiences among people across Meta technologies.
Before you begin
- Note: If your account is new or if you’ve recently linked to an existing account, it may take a few weeks before you’re able to create or share a customer list custom audience. If your new account is part of a tenured business portfolio, you may be able to go through business verification.
- You must be the owner of the ad account connected to Meta Business Manager, or have admin or advertiser permissions.
Create a customer list custom audience
- Open Audience in Ads Manager.
- Select Create audience then Custom audience. If you haven't created an audience before, select Create a custom audience.
- Select Customer list, then Next.
Note, sometimes Meta tries to prevent this. If you need to, add an 'order date' field and put it as the day before today.
Prepare your list: Follow the instructions to format your customer list. Learn more. Select Next.
Add Customer List: You can Upload a list or Paste comma separated values. (Optional) You can Name your audience or + Add description. Accept the custom audience terms, then select Next.
Match columns:
Select Import and create.
You will return to Audience and see your audience Populating.
We’ll let you know when your audience is Ready. Then you can create an ad to reach your new custom audience, or create a lookalike audience to find new people who share similar behaviors and interests with your existing customers.
Note: Before we use your uploaded list for the matching process, the information in your customer list is hashed and will be unidentifiable at an individual level. Hashing is a type of cryptographic security method that turns your identifiers into randomized code and cannot be reversed. (Depending on the size of your list, this may take a few minutes.)
