# Audience sync

The **Audience sync** element updates a Meta Ads custom audience when users reach this step in a journey. Choose **Add users to audience** to include them in ad targeting, or **Remove users from audience** to stop showing ads to them.

## Before you start

Make sure Meta Ads integration is configured for your project. If integration is missing, the element shows **Configure your Meta Ads account** and cannot run sync.

Learn how to set up integration: [Meta Ads integration](/product/integrations/meta-ads-integration/).

For better match quality, configure user data mapping in Meta integration settings using **Map user data**.
