What changed: Linked the citations, made the opening H2 a question, and added the free fatigue forecast tool.
Creative fatigue in Meta ads is the performance decline that occurs when an audience sees the same ad too many times. The median creative lifespan is 14-18 days. The 5 detection signals are: frequency above 3.0, CTR declining 2+ periods, CTR below 50% of peak, CPL rising 20%+, and impressions growing while clicks stay flat.
Key Takeaways
Creative fatigue is the #1 silent killer of Meta ad performance. The median creative lasts 14-18 days before fatigue sets in. Once frequency passes 3.0 and CTR drops below half its peak, your ad is costing you money — not making it.
Fatigue follows a predictable pattern: CTR peaks in the first 5-7 days, plateaus briefly, then declines steadily. CPL starts rising as the same audience sees the ad repeatedly. Frequency climbs above 3.0 for general audiences (4.0 for e-commerce, 2.5 for B2B). By the time you notice performance dropping, you've already wasted 3-5 days of budget.
1) Frequency above 3.0 (4.0 e-com, 2.5 B2B). 2) CTR declining for 2+ consecutive periods. 3) CTR below 50% of its peak value. 4) CPL rising 20%+ above its 7-day average. 5) Click-through rate diverging from impression growth (impressions up, clicks flat).
AutoAdy uses Kaplan-Meier survival analysis to estimate each creative's remaining lifespan. CUSUM change-point detection identifies the exact moment performance starts trending down — typically 3-5 days before it becomes obvious in the dashboard. This gives you time to prepare replacement creatives before performance craters.
Maintain a creative pipeline of 3-5 ready-to-launch ads at all times. Rotate creatives every 14 days proactively, don't wait for fatigue. Test different formats (video, carousel, static) to extend total campaign lifespan. Use dynamic creative testing to find winners faster.

FAQ
The median Meta ad creative lasts 14-18 days before fatigue sets in. High-spend campaigns can fatigue in as little as 7 days, while niche audiences with low frequency may last 30+ days.
For general audiences, frequency above 3.0 signals fatigue. E-commerce can tolerate up to 4.0 (purchase intent is stronger). B2B should stay below 2.5 due to smaller, more sensitive audiences.
Temporarily, yes. Expand your audience to reach new people, adjust placements, or change the ad copy. But these are band-aids — the only real fix is fresh creative. Plan for 3-5 replacement ads in your pipeline.
Check the performance timeline. A bad ad never performs well — low CTR from day one. A fatigued ad performed well initially and then declined. If CTR peaked above 1.5% then dropped below 0.75%, that's fatigue, not a bad ad.
