An audience created by finding people similar to your existing customers or leads.
A lookalike audience is a targeting option that finds people similar to your existing customers, website visitors, or email subscribers.
Lookalike audiences find new people who resemble your best existing customers. They're one of the most powerful prospecting tools because you're targeting people statistically likely to convert based on the patterns of your actual buyers. A well-built lookalike audience can dramatically improve cold traffic performance.
