What changed: Turned the vertical thresholds into a table, made the H2s question-form, and added the fatigue forecast and saturation curve.
Facebook ad frequency is average times each person sees your ad. Above 3.0 is too high for most verticals — CTR drops 25-40%, CPA rises 30-50%. E-commerce tolerates 4.0, B2B fatigues at 2.5.
Key Takeaways
The general ceiling is 3.0, but tolerance moves with intent. Warm retargeting audiences accept far more repetition than cold prospecting, and small B2B pools burn out first.
| Audience | Frequency ceiling |
|---|---|
| Retargeting | 5.0-7.0 |
| E-commerce prospecting | 4.0 |
| Local services | 3.5 |
| General audiences | 3.0 |
| B2B / SaaS | 2.5 |
| Cold prospecting | Below 2.5 |
1-2: optimal. 3.0: CTR declines, CPA rises. 4.0+: CTR down 25-40%, CPA up 30-50%. 6.0+: audience hides/reports. Damage accelerates — each point above 3.0 cuts reach efficiency 15%.
Frequency caps only on Reach objective. For others: expand audiences, rotate creatives every 2-3 weeks, exclude converters, increase budget gradually to reach new people.

FAQ
1.5-2.5 for cold prospecting. Retargeting can go 5-7. Above 3.0 on cold = expand audience or refresh creatives.
Only on Reach objective. Others: control indirectly via audience expansion, creative rotation, exclusion audiences.
Meta charges per impression regardless of repeats. At 4.0+ frequency, you pay 4x per unique person vs 1.0.
