What changed: Made the H2s question-form, linked the citations, and added the drop diagnostic and fatigue forecast.

Declining performance is gradual CPA increase or ROAS decrease. Diagnosis: 70% creative fatigue, 20% audience exhaustion, 10% external factors like algorithm updates or seasonal shifts.

Key Takeaways

  • ✓70% of declines trace to creative fatigue — check frequency and CTR first
  • ✓5-step diagnosis: frequency, CTR trend, CPM, new audience test, landing page audit
  • ✓Previously successful ads revive with new creative on the same audience

Why is my Facebook ad performance dropping?

1: Frequency above 3.0 = fatigue. 2: 14-day CTR declining = creative fatigue. 3: Rising CPM + stable CTR = audience competition. 4: New audience improves CPA = old exhausted. 5: Stable ads but fewer conversions = post-click issue.

How do you fix creative fatigue?

Rotate 3-5 new creatives. Change video hook in first 3 seconds. Switch format. Same offer, new visuals. Restores 70-80% of peak within 5-7 days.

Audience and Algorithm Fixes

Exhaustion: expand lookalike 1% to 3%, add interests, test broad. Algorithm: duplicate campaign for fresh learning phase. Seasonal: reduce budget, scale back when competition eases.
