Lookalike Audience
A lookalike audience is a targeting type where an ad platform models a seed audience — such as a customer list or high-value converters — and finds new users who share similar attributes and behaviors. As of 2026, the tactic has shifted on Meta: with smaller, noisier pixel signals post-iOS tracking changes, classic 1% lookalikes often perform only marginally better than broad targeting, and Meta has folded lookalike expansion into Advantage+ audiences (its machine-learning targeting layer that treats your seed as a suggestion rather than a hard boundary). The durable best practice is to supply rich first-party seeds and let the system expand from there.
