Why is ad frequency important in detecting fatigue?

Ad frequency is critical in detecting fatigue because it indicates how often your audience is exposed to the same ad. A high frequency suggests that users are likely seeing the ad too many times, which can lead to creative fatigue. When users are overexposed, they tend to ignore the ad, resulting in decreased engagement and lower click-through rates (CTR).

Monitoring frequency allows advertisers to gauge when an ad has reached its saturation point. By setting frequency caps, advertisers can prevent overexposure and maintain audience interest. This approach helps in keeping the ads fresh and effective.
