What is Custom Audiences ?
A Custom Audience from a customer list is a type of audience you can create made up of your existing customers. You can target ads to the audience you’ve created on Facebook, Instagram, and Audience Network.
You upload, copy and paste or import your hashed customer list, then Facebook use the hashed data from it to match the people on your list to people on Facebook.
It’s easier to sell to current customers than to look for new ones, so strengthen your existing connections by using Custom Audiences. Facebook will compare your data with theirs to help you find the people you know on Facebook.
If you have a customer list or data from your site, like purchaser email addresses, you’re ready to get started.
Once you create your Custom Audience, your information will be encrypted to protect customer relationships and you’ll be set to reach more people on Facebook.
