Lookalike Audience: Writer vs Hadrian
DIRECT ANSWER
A lookalike audience is a targetable group of people or accounts that an ad platform identifies as sharing significant behavioral and demographic similarities with a seed audience — typically your best customers, highest-LTV cohort, or converted leads.
