Set format frequency caps

Limit the number of creatives that can serve in an ad unit, or across the network, within a given time period. Format frequency caps are useful when you want to set limits across formats like rewarded ads or web interstitials.

You can apply these frequency caps at the ad unit or network level. If both frequency caps apply to an ad request, the more restrictive frequency cap applies to that ad request.

Set format frequency caps

1. Sign in to Google Ad Manager.
2. Choose whether to add the frequency caps at the ad unit or network level.
   • Ad unit: Click Inventory, then Ad units, then an ad unit's name, and then Settings.
   • Network: Click Inventory, then Network settings.
3. Select the checkbox next to Set format frequency caps.
4. Select the desired format from the dropdown.
5. Enter a maximum number of impressions per user and then set how often the cap will be reached.

   Example

   Set a frequency cap so a user will be served at the most 10 creatives in the ad unit every 2 weeks.

6. Click Add format frequency cap to add more frequency caps as needed. Combining frequency caps can help ensure that users don’t see creatives in the same ad unit too often.

   Example

   Set one frequency cap of 1 impression per hour, and a second frequency cap of 3 impressions per day. Ad Manager will enforce both rules: a user can't be served creatives in the ad unit more than once per hour or more than three times per day.

7. Click Save.
