Audience reach counts and health checks

Before an advertiser spends on an audience, two questions matter: how many people can it reach, and is it still healthy?

Reach counter

The Programmatic DMP shows a reach count for every audience — how many people it can reach — and, since v1.5, an audience size estimate while you set targeting. Use it to:

• Avoid launching on an audience too small to deliver.
• Compare audiences before choosing one.
• Explain to a client why a retargeting campaign spends slowly.

Daily health checks

Each audience gets a daily health check, which tells you when it is too small or stale. A stale audience usually means its source stopped feeding it — for example:

• The website tag was removed from the site (visitor audiences).
• A customer list hasn't been re-uploaded in months.
• Conversion tracking broke, so the converter audience stopped growing.

Sync status

The sync page shows each audience per channel — programmatic, search and social — with a status such as Ready or Syncing.

What to do when an audience is too small

1. Widen the lookback window (up to 180 days).
2. Combine sources, e.g. visitors and engagers.
3. Use a lookalike built from it.
