Definition
Lookalike audiences use a high-quality seed (like converters, high-LTV customers, or engaged leads) to find new people who resemble them based on platform data signals. Used in Meta/LinkedIn/Google, they expand reach to likely converters while maintaining targeting efficiency.
Why This Matters
Lookalikes scale prospecting with better fit than broad interest targeting, often yielding lower CPL/CAC when the seed is strong.
Common Types
Customer Lookalikes
Seeded with paying customers or high-LTV users.
Lead Lookalikes
Seeded with MQL/SQL/PQL leads for more qualified prospects.
Engagement Lookalikes
Seeded with high-engagement site visitors or email engagers.
Real-World Examples
1High-LTV Seed
Using top 10% LTV customers as seed improved ROAS on Meta.
2SQL Seed
Lookalikes from SQLs delivered lower CAC than generic interest targeting.
3Engager Seed
Lookalikes from long-session visitors outperformed broad audiences.
4Country-Specific
Separate seeds per region for localized performance.
