Digital marketing term
Frequency
Frequency is a performance metric that expresses how many times, on average, a single user has seen the same ad within a given time period.
Detailed explanation
This metric is calculated by dividing total impressions by the number of unique users reached. A low value can mean the message isn't being repeated enough, while a very high value means the same people are being shown the ad too often.
The ideal level depends on the campaign goal; brand awareness campaigns can tolerate somewhat higher repetition, while performance campaigns generally see excessive repetition lead to declining CTR and rising costs.
This value is monitored regularly, and frequency capping is applied or the audience is expanded as needed to prevent over-exposing the same users.
