About Lookalike Audiences

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.


When you create a Lookalike Audience, you choose a source audience (a Custom Audience created with information pulled from your pixel, mobile app or fans of your Page). We identify the common qualities of the people in it (for example, demographic information or interests). Then, we deliver your ad to an audience of people who are similar to (or “look like”) them.

You can choose the size of a Lookalike Audience during the creation process. Smaller audiences more closely match your source audience. Creating a larger audience increases your potential reach, but reduces the level of similarity between the Lookalike Audience and source audience. We generally recommend a source audience with between 1,000 to 50,000 people. Source quality matters too. For example, if a source audience is made up of your best customers rather than all your customers, that could lead to better results.
