Good frequency for Facebook Ads?

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.

Facebook Ad Frequency: When Is It Too High?

Last updated: April 5, 2026

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

✓General threshold: 3.0 — CTR drops 25-40%, CPA rises 30-50% above this
✓E-commerce tolerates 4.0, B2B fatigues at 2.5, retargeting tolerates 5-7
✓Each 1.0 above 3.0 reduces reach efficiency by ~15%

Thresholds by Vertical

E-commerce: 4.0. B2B/SaaS: 2.5. Local services: 3.5. Retargeting: 5-7. Cold prospecting: keep below 2.5.

How Frequency Kills Performance

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%.

Managing Frequency

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.
