What are Lookalike Audiences?

Targeting people similar to your existing customers or website visitors.

Understanding Lookalike Audiences

Lookalike audiences (also called similar audiences or twin audiences) are targeting segments created by ad platforms that match the characteristics of your existing customers or engaged users. Platforms analyze your source audience and find other users with similar demographics, interests, and behaviors.

Lookalike audiences are powerful for prospecting because they help you find new customers who resemble your best existing customers. Quality of the source audience matters—building lookalikes from high-value purchasers typically performs better than lookalikes from all website visitors. Most platforms let you control audience size through a similarity percentage—1% is most similar (smaller reach), 10% is broader (larger reach but less similar).
