Ad Fatigue
The decline in ad performance that occurs when an audience sees the same ad too many times.
What Ad Fatigue means
Ad fatigue happens when the frequency of ad exposure becomes too high, leading to declining click-through rates, increased cost per action, and potential negative brand sentiment. While primarily a performance concern, ad fatigue has compliance implications — some platforms interpret high-frequency, low-engagement ads as a poor user experience and may reduce delivery or flag the ads. Monitoring frequency metrics and refreshing creative regularly helps maintain both performance and compliance. Platforms like Meta provide frequency caps and creative rotation tools to combat ad fatigue.
