How to create a lookalike audience on Meta Ads Manager

The size of your lookalike source may decrease because it may not include some iOS 14 users. Using it as a lookalike source will not affect your lookalike audience's size, but may affect the accuracy of the lookalike audience. Learn how iOS 14 may affect your ad strategy.

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.

Note: Targeting options are limited for audiences that include people under the age of 18 in most countries, under 20 in Thailand and under 21 in Indonesia. Learn more about targeting options to reach teens and how this update may affect your ad sets.

Make sure that you're an admin for the Page or Meta pixel that you're creating it from. If you're making a lookalike audience from a custom audience, you need to have the role of admin or advertiser on the ad account.

If you're also an administrator or developer of an app, you may create a lookalike audience for that app in addition to any other apps that have been shared with that ad account.

1. Go to your Audiences. (You can also create a lookalike audience during ad creation in Meta Ads Manager).
2. Select the Create audience drop-down and choose lookalike audience.
3. Choose your source. A source can be a custom audience not created with your pixel data, your mobile app data or fans of your Page. Consider using a group of 1,000 to 50,000 of your best customers based on lifetime value, transaction value, total order size or engagement.
4. Choose the country/countries where you'd like to find a similar set of people.
5. Choose your desired audience size with the slide.
6. Select Create audience.

Once you're finished, it may take 6-24 hours for your lookalike audience to be created. Going forward, your audience will refresh every 3-7 days (as long as you're still actively targeting ads to it). However, you don't need to wait for your lookalike audience to update to use it.

To find out when your audience was last updated, visit your Audience Manager page > Availability column > look for the date.

If you are unable to delete your audience in Audience Manager, you can contact our support team. To request an audience deletion, go to Help, select your ad account and fill in the form.
