The short answer

A custom audience is one you build in Meta's ads manager from sources you own: your customers' numbers or emails, site visitors recorded by the pixel, or those who watched your videos, engaged with your page and account or messaged you. You use it for retargeting, or as the seed for a lookalike audience.

Why does Custom audience matter to a seller?

Because someone who knows you is closer to buying than a stranger: someone who messaged and did not order, or viewed a product and did not finish. But a customer list may only be uploaded for people whose data you collected with consent and told so in your privacy policy.

To build a clean customer list from the start: collecting customer data with consent, and say so in your privacy policy.

Frequently asked questions

1

How does a custom audience differ from a lookalike?

A custom audience is people who already know you; a lookalike is new people Meta picks because they resemble your custom audience.

2

Can I upload numbers I bought?

No; bought lists break data protection laws and Meta's terms alike.
