What is ad fatigue?
Ad fatigue happens when people see the same ad so many times that they stop responding to it. Click-through and conversion rates fall, while costs often rise. Refreshing the creative or widening the audience usually helps.

Signs of ad fatigue
The common pattern is a rising frequency alongside a falling click-through rate. Costs per click or per conversion may creep up at the same time, even though nothing else about the campaign changed.
Negative feedback is another clue. On social platforms, more people may hide the ad or report it.
What causes ad fatigue
Fatigue builds when a small audience sees a small set of ads again and again. Long campaign runs and heavy retargeting make it more likely, because the same people are reached over and over.
How to fix and prevent it
Rotate in new creative before performance drops far, not after. Different images, hooks, and formats all count as fresh to the viewer.
You can also widen the audience, use a frequency cap where the platform offers one, or exclude people who already converted.
Common questions
How do you know if an ad is fatigued?
Look for a falling click-through rate or conversion rate while frequency climbs. If costs rise with no other change to the campaign, fatigue is a likely cause.
How often should you refresh ad creative?
There's no fixed schedule. Audience size, budget, and channel all change how fast ads wear out, so watch your own metrics and refresh when results start to slip.
What frequency is too high?
It varies by platform, audience, and goal. Compare frequency with your results over time, and treat the point where performance starts to decline as your own limit.
Does ad fatigue affect search ads?
It's most common in display, video, and social ads, where the same people see the same image repeatedly. Search ads show in response to a query, so fatigue is usually less of a problem.
