What it measures
Facebook ad frequency is the average number of times each unique person sees your ad over a campaign.
Formula
Frequency = Impressions ÷ Reach
Worked example
90,000 impressions delivered to 45,000 unique people gives an ad frequency of 2.0.
Typical benchmarks
- Prospecting
- 1-2
- Retargeting
- 3-5
- Fatigue zone
- 5-7+
How this calculator works
Frequency = impressions ÷ reach. Keep an eye on it: cold-audience frequency above 3–4 often signals fatigue, rising costs, and falling CTR. Refresh creative or expand the audience when it climbs.
Frequently asked questions
What is a good ad frequency? +
For prospecting, 1–2 is ideal. Retargeting tolerates 3–5. Above 5–7, expect diminishing returns and rising costs.
How do I reduce ad frequency? +
Expand your audience, add fresh creative, cap frequency in campaign settings, and rotate ads to avoid showing the same one too often.
What frequency signals ad fatigue? +
For cold audiences, frequency above 3-4 often coincides with falling click-through rates and rising costs, the classic signs that viewers are tiring of the ad.
Is high frequency ever good? +
Yes, in retargeting and short promotional bursts, repeated exposure can drive conversions. The concern is high frequency on cold prospecting audiences where it wastes budget.
How do I lower ad frequency? +
Expand or refresh your audience, rotate in new creative, set a frequency cap in reach-and-frequency campaigns, and pause ads that are over-served.
