Definition
Creative fatigue happens when performance declines because the audience has seen the same creatives too many times.
How to use it
- Monitor frequency and CTR trends to detect fatigue.
- Rotate creatives and refresh offers to maintain performance.
Common mistakes
- Refreshing creative without changing the underlying message/offer (fatigue returns quickly).
- Blaming fatigue when the real issue is landing-page or pricing changes.
Why this matters
This term matters because it affects how you interpret performance and make budget decisions. If you use inconsistent definitions or windows, ROAS/CPA can look "better" while profit gets worse.
Practical checklist
- Write a 1-line definition for "Creative Fatigue" that your team will use consistently.
- Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
- Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
- Sanity-check with a related calculator from the same category on MetricKit.
- Read the related guide (e.g., Frequency and creative fatigue: diagnose performance decay and fix it) for context and common pitfalls.
