Digital marketing term
Ad Fatigue
Ad Fatigue is a performance problem where the same ad's effectiveness declines from being shown repeatedly to the same audience, causing click-through and conversion rates to drop over time.
Detailed explanation
This typically occurs once the frequency metric crosses a certain threshold; as users see the same visual or message over and over, they start ignoring the ad, and negative brand perception can sometimes develop.
Early signals of this problem include declining CTR, rising CPC, and a falling conversion rate. A lack of creative variety and overly narrow targeting cause this effect to appear faster.
The fix typically involves increasing creative rotation, expanding the target audience, or applying frequency capping to limit how often the same user sees the ad — all of which can revive campaign performance.
