A lookalike audience is a powerful targeting tool that finds new people who look and behave like your best existing customers. If you have 500 buyers on your online store, Facebook can analyze their demographics, interests, and online behavior to create a new audience of similar people — people who are highly likely to be interested in your products too.
Lookalike audiences work across Facebook Ads, Google Ads, and TikTok Ads. The key to success is providing a quality source audience — your customer email list, website visitors, or page followers. The better your source data, the more accurate your lookalike audience will be. It's essentially letting the platform's algorithm find your next customers for you.
