Lookalike Audience

ConceptualMarketingStrategies

Definition

Lookalike Audience: A lookalike audience is a targeting method that finds new users who share characteristics with your existing customers or engaged users. Platforms like Facebook and Google analyze your seed audience's demographics, interests, and behaviors, then find similar users at scale. Lookalikes help startups efficiently expand reach beyond their known audience.

Example Usage

β€œWe built a lookalike audience from our highest-LTV customers, reducing our CPA by 40% compared to interest-based targeting.”

Common Misconceptions

Bigger seed audiences are better. Quality matters more; use your best customers, not all customers.
1% lookalikes are always best. Sometimes 2-5% lookalikes scale better with acceptable performance trade-offs.
Lookalikes work instantly. They need sufficient seed data (usually 1,000+ users) to work effectively.
