Why is my Meta ROAS dropping?
Six common causes, in order of frequency: creative fatigue, audience saturation, attribution shifts, seasonality, competitor spend, and account-level changes. The fix is creative variance 80% of the time.
Creative fatigue (80% of cases)
Most-common cause. Frequency over 3 + flat CTR + rising CPM = fatigue. Fix: ship 5+ new variants/week, retire bottom performers. Don't trust 'just need more audiences' — fresh audiences with stale creative still fatigues.
Attribution drift
iOS update or pixel mis-configuration silently changes attribution. Check: Meta-attributed revenue vs Shopify-attributed revenue. If the gap widened in the last 30 days, you're seeing attribution drift, not real ROAS drop.
Seasonality + competitor spend
Q4 + Black Friday compression pushes CPMs up 30-60% for the same audience. Your ROAS dropped because CPM rose, not because your conversion rate fell. Triple Whale or in-platform CPM trend chart will show you this in 30 seconds.
The tools worth comparing
- Arcads — Best avatar quality on the market; deepest demographic actor library.
- Icon — Breadth — fewer tools to glue together. Direct publish to Meta.
- Triple Whale — Attribution + dashboard built for ecom — not retrofitted from B2B SaaS analytics.
