Our MacBook Air CTR on Meta has been declining for 3 weeks straight. Creatives getting stale or have we tapped out the audience?
Both factors are present, but the root cause is different from what the surface metrics suggest.
Verdict: 65% audience saturation, 35% creative fatigue
Audience saturation evidence:
• Average frequency on your "MacBook Air M3" ad sets hit 8.1 this week (up from 3.4 three weeks ago)
• First-impression CTR is still solid at 1.9% — close to your 3-week-ago average of 2.1%
• Repeat-impression CTR has cratered: 1.4% down to 0.4%
• Your addressable audience for "tech professionals, 25–44, interested in laptops" is approximately 220K. At current spend, you're cycling through 82% of them weekly
Creative fatigue evidence:
• First-impression CTR did dip slightly (2.1% to 1.9%), suggesting even new viewers are less engaged
• Your hero creative — the "Supercharged for Everything" lifestyle shot — has been running for 38 days
• Meta's ad relevance diagnostics show quality ranking dropped from "above average" to "average" this week
• Engagement rate on the "Compare MacBook Air vs. Pro" carousel dropped 22%
The key insight: If this were purely creative fatigue, first-impression CTR would have dropped more sharply. The fact that new viewers still respond reasonably well but repeat viewers have essentially stopped clicking tells us the audience pool is exhausted first, creatives second.
Recommended approach:
1. Immediately — Expand your lookalike seed from 1% to 3% and add "interested in: productivity software, remote work" to widen the addressable pool by ~150K
2. This week — Rotate in 2–3 fresh MacBook Air creatives. The M3 benchmark comparison and the student lifestyle angle have historically performed well for refreshes
3. Don't do — Increase budget. That will accelerate the saturation and burn through the expanded audience faster
