The performance decline that happens when an audience has seen the same ad creative too many times, becoming less responsive to it even though the underlying offer hasn't changed.
Why it matters
Creative fatigue is one of the most common reasons a previously strong-performing ad quietly declines — the fix isn't usually a new offer, it's fresh creative, and recognizing fatigue early prevents a team from wrongly concluding the offer or channel itself has stopped working.
In a sentence
"CTR had been trending down for two weeks — a sign of creative fatigue, so we refreshed the ad set instead of pulling the whole campaign."
