What Is Ad Frequency? Why It Matters for Fatigue and Budget (2026)

Ad frequency is the average number of times each person saw your ad: impressions ÷ reach. Here's how to read it, the link to ad fatigue, and how to manage frequency before it wastes budget.

Frequently asked questions

What is a good ad frequency?
There's no universal number — it depends on the platform, audience size and campaign length. As a rough guide, performance on cold audiences often softens once frequency climbs past about 2–3 in a short window, but the trend matters more than the threshold.
Is high ad frequency bad?
Not always — some repetition helps recall. It becomes a problem when frequency keeps rising while CTR falls and CPM climbs, which signals fatigue and wasted spend. Manage it by refreshing creative and widening the audience.
How is frequency related to ad fatigue?
Frequency is one of the earliest fatigue signals. When the same people see an ad too often, CTR drops and costs rise. Rising frequency together with falling CTR is the reliable sign that fatigue has set in.
