Ad rotation is automatically applied at the ad set level. As of June 23, 2025, all ad sets created via Ads Manager use even rotation by default. This means the ads within an ad set will be delivered approximately the same number of times over the course of the ad set’s flight dates. You can check the delivery of each ad in Ads Manager by clicking into the ad set.

This is applicable to all ad placements & all ad formats. Advertisers cannot modify the ad rotation setting.

Example: If an ad set contains 3 ads, each ad will be delivered as evenly as possible over time. While Ad 1 might serve twice before Ad 2 or Ad 3 is delivered, overall delivery will remain balanced.
