A Custom Audience made from a customer list is a type of audience you can create to help build your reach. It is made of information, called identifiers. that you have collected about your customers such as email address, phone number and address. You provide this information to Facebook.

When you create a Custom Audience from your website, you have several options to customise it.

• Website Custom Audiences
• Mobile app Custom Audiences
• Custom Audiences from a customer list
• Engagement Custom Audiences

Website Custom Audiences

Custom Audiences from your website is a targeting option that matches people who visit your website with people on Facebook, using the Facebook pixel. You can then create an ad to show to that audience.

You can create a Custom Audience from your website for any group of visitors that like to reach with targeted Facebook ads. For example, you can run a campaign to reach people who visited a product page but didn't complete a purchase to encourage them to go back to the website to do so. Or, you can create an audience of everyone who's visited your website in the past 30 days.

Customer List for Custom Audience

To make a Custom Audience from a customer list, you provide information about existing customers that is matched with Facebook profiles. The customer list can either be a CSV or TXT file that includes identifiers such as email, phone number, address.

Lookalike Audience

When you are ready to grow your business, you can use your Custom Audience to create a Lookalike Audience. A Lookalike Audience is a way to reach new people who are likely to be interested in your business because they're similar to your best existing customers.
