Ad Rotation is the process of alternating between different ads in the same placement to test variations or avoid ad fatigue. Ad rotation is commonly used in A/B testing, where different creatives are shown to see which performs best. Platforms often offer settings to automate ad rotation, making it easier to test performance.

Ad rotation helps marketers gather insights into which ads resonate most with users. By controlling rotation frequency, advertisers balance exposure and prevent ad fatigue, leading to higher engagement rates and more efficient campaign management.
