Short answer
Check the Delivery column in Meta Ads Manager. It shows the status of each campaign, ad set and ad, such as Active, Learning, In review or Rejected, and flags problems that stop delivery.
Statuses that mean it is running
- Active: the ad is running normally.
- Learning: the ad set is still in the learning phase. It is delivering, but performance is less stable and cost per result is usually higher.
- Learning limited: the ad set is running but did not get enough results to exit learning.
Statuses that mean it is not running yet
- In review: Meta is checking the ad against its Advertising Standards. Most ads are reviewed within 24 hours, though some take longer.
- Processing: your changes are being saved. This usually takes minutes, but some updates take up to 8 hours.
- Preparing: the ad passed review and is being matched to bids and audiences before its first impression.
- Scheduled, Rejected, Off or Completed: it is waiting, blocked, switched off or finished.
In practice
Check all three levels. A campaign can show as active while its ad set or ad is still in review. Hover over warnings or errors to see what to fix. For app campaigns, also confirm in your MMP that installs and in-app events are arriving.
