What Is Frequency?

Definition

Frequency is the average number of times each reached person saw an ad during the selected period.

How Frequency Works

Meta calculates frequency as impressions divided by reach. Because it is an average, some people may see the ad many more times than others.

A Simple Example

A campaign with 300,000 impressions and 100,000 people reached has an average frequency of 3.

Why Frequency Matters

Frequency helps assess repetition, audience saturation and the need for new creative.

Common Misreading

There is no universal frequency ceiling. A high number may be appropriate for a short promotion or warm audience, while a low number can still perform poorly.
