What is Lookalike Audience?
A targeting audience that resembles your best existing customers.
Definition
Lookalike audiences are platform-generated audiences based on the characteristics of a seed audience (like your customer list or website visitors). The platform analyzes the seed group's demographics, interests, and behaviors, then finds new users who match that profile. Lookalike percentages indicate similarity: a 1% lookalike is the most similar (and smallest), while a 5-10% lookalike is broader. Start with 1% lookalikes of your highest-value customers for best results.
Example
A brand uploads a list of 5,000 customers who spent $100+ and creates a 1% lookalike audience on Meta. This 2.3 million-person audience converts at 3x the rate of interest-based targeting.
