What is Custom Audience on Facebook?

Custom Audience is an ad targeting option that lets you find your existing audience among people who are on Facebook.

You can use sources like customer lists, website or app traffic, or engagement on Facebook, to create Custom Audiences of people who already know your business. 

You can check out the Facebook ‘About Custom Audiences’ page for more.
