What Makes a Good Lookalike?
The quality of your lookalike audience depends on two factors: your seed audience and your optimization strategy.
Seed Audience Best Practices
Quality > Quantity
A seed of 1,000 high-value customers performs better than 10,000 random website visitors.
Ideal Seeds
- Purchasers with high lifetime value
- Repeat customers (2+ purchases)
- High-value leads (closed deals)
Seeds to Avoid
- All website visitors
- Bounced traffic
- Low-value transactions
Lookalike Strategy
Percentage Selection
- 1%: Most similar, smallest reach
- 2-5%: Good balance
- 5-10%: More reach, less precision
Layered Lookalikes
Combine lookalikes with:
- Interest targeting
- Behavioral signals
- Geographic filters
Conclusion
Effective lookalikes start with quality seeds and end with smart layering strategies.
