Lookalike audience
Last updated 2026-06-14
Definition
A lookalike audience is a new group of people an ad platform builds to resemble a seed audience you supply — usually your best customers. The platform finds users with similar traits and behaviour, so you reach fresh prospects who look like proven buyers. Quri helps you define that seed from your own first-party customer data.
How to do this in Quri
- Identify a high-value seed audience, such as your repeat buyers, from first-party data.
- Use Quri to shape that seed segment from the events and revenue it reads.
- Hand the seed to your ad platform to build a lookalike from it.
- Track the lookalike’s CPA and ROAS in Quri to see if it finds real buyers.
Frequently asked
- How big should my seed audience be?
- Large enough for the platform to find a pattern, but tight enough to be genuinely your best customers. A focused, high-value seed usually beats a big, loose one.
- Why start a lookalike from first-party data?
- A lookalike is only as good as its seed. First-party data you own — real buyers, real behaviour — makes a sharper seed than a borrowed list, which is why Quri builds it from your own events.
