Lookalike Audience
A targeting group built by finding users who resemble an advertiser's existing customer or engagement source list.
What it means in practice
The platform analyzes traits associated with a source audience and identifies similar people within a selected market. Source quality, source size, similarity range, and platform data availability shape how the audience is constructed.
Why it matters
Choosing a weak or mismatched source can direct creator ads toward people with limited relevance to the campaign goal.
How it is used
A brand builds a lookalike from recent purchasers and serves creator product demonstrations to the resulting prospecting audience.
