Lookalike Audience
A lookalike audience is a group of people Meta finds who resemble a source list you provide, such as your existing customers.
Example
Upload a list of past members, and Meta builds an audience of people with similar traits to show your ads to.
How to read it
The source list decides the quality of the lookalike. Feed it your best customers.
Why it matters
Lookalikes can help reach new people likely to buy, especially when your source list is made of real, paying customers.
Common mistakes
- Building lookalikes from low-quality lists like all website visitors.
- Using a source list that's too small.
- Relying on them when broad targeting with good data would do better.
How to improve Lookalike audience
- Build lookalikes from paying customers, not all leads.
- Refresh the source list regularly.
- Test against broad targeting with good conversion data.
- Keep location limits for local businesses.
