Lookalike Audience
A lookalike audience is a new advertising audience built to resemble an existing group of customers, usually your best ones, by finding people with similar attributes and behavior. Built from first-party seed data, lookalikes are a powerful way to expand reach efficiently.
You supply a seed audience, such as high-value customers, and the ad platform finds users who resemble them, extending acquisition to people most likely to convert.
The quality of a lookalike depends on the quality of the seed. A clean, resolved first-party seed produces sharper expansion than a noisy or fragmented list.
