Creative fatigue is the performance decay that sets in when an audience has seen an ad too many times — engagement drops, costs rise, and the ad that was working stops.
Definition
Fatigue shows up as a pattern: frequency climbs, CTR declines on a stable audience, then CPA deteriorates. It arrives fastest on small audiences and high-frequency placements. The fix is refresh — new angles, formats, or hooks — not just new colorways of the same concept, which fatigued audiences treat as the same ad.
Why it matters
Fatigue is the most common silent killer of scaled social campaigns: the account looks unchanged while results erode. Because CTR decay leads CPA decay by days, teams that monitor fatigue signals refresh before paying for it — teams that watch only CPA refresh after.
In agentic execution
Adlyse's agents track fatigue signals continuously and propose rotations or pauses before decay compounds — the kind of high-frequency vigilance that human teams can't sustain across every ad set, executed with approval.
