Decision rule
The weaker your seed quality, the less you should expect lookalikes to outperform broad targeting.
How to compare

- Broad targeting relies heavily on creative and conversion optimization.
- Lookalikes rely heavily on seed quality and platform signal health.
- Both need exclusions and measurement discipline when testing.
Common mistake
Using a seed audience mixed with low-quality leads, giveaway traffic, or old customers can mislead lookalike delivery.
FAQ
Are lookalikes still useful?
Yes when the seed is high-quality and the account has enough signal, but broad targeting often works well with strong creative.
Should I test broad and lookalike together?
Test them separately enough to understand signal, but avoid over-fragmenting small budgets.
What seed audience is best?
High-value purchasers, repeat buyers, or profit-positive customers are stronger than all visitors or low-intent leads.
