A lookalike audience is a way your ads can reach new people who are likely to be interested in your business because they share similar characteristics to your existing customers.

To create a lookalike audience, our system leverages information such as demographics, interests and behaviors from your source audience to find new people who share similar qualities. When you use a lookalike audience, your ad is delivered to an audience of people who are similar to (or "look like") your existing customers.

When you create your lookalike audience, you can use a percentage range to choose how closely you want your new audience to match your source audience. The size you choose depends on your goals. Smaller percentages more closely match your source audience, but larger percentages create a bigger, broader audience. However, the quality of your audience also matters. For example, you may get better results depending on your goals if you use an audience made from your best customers rather than one that includes all your customers.

Note: Targeting options are limited for audiences that include people under 18 (or older in some countries). Learn more about targeting options to reach teens and how this update may impact your ad sets.
