What is a Frequency?
The average number of times each person saw your ad.
How Frequency Works
Frequency is the average number of times each unique user saw your ad or content during a campaign. It's calculated by dividing total impressions by reach. For example, 100,000 impressions and 25,000 reach = 4.0 frequency.
Optimal frequency depends on campaign goals. Brand awareness campaigns benefit from 3-7 exposures for message retention. However, excessive frequency leads to creative fatigue—when users see the same ad too many times, performance declines and they may develop negative brand associations. Monitor frequency at the ad level and refresh creative or adjust targeting when performance drops. Social platforms provide frequency data; search and display campaigns require more manual monitoring.
Frequently Asked Questions
What is a Frequency?
The average number of times each person saw your ad.
Frequency is the average number of times each unique user saw your ad or content during a campaign. It's calculated by dividing total impressions by reach. For example, 100,000 impressions and 25,000 reach = 4.0 frequency.
Why is Frequency important?
Frequency determines whether you're achieving enough exposures for message retention versus wasting budget on ad fatigue. Too little frequency (under 2-3) means people forget your message before converting. Too much frequency (over 8-10) creates ad fatigue, declining performance, and potential brand damage. Managing frequency is critical for efficient spending—refreshing creative when fatigue sets in can improve performance 30-50%.
How do you calculate Frequency?
Frequency = Total Impressions ÷ Reach. For example, if your campaign delivered 500,000 impressions to 100,000 unique users, frequency is 500,000 ÷ 100,000 = 5.0 (each person saw your ad an average of 5 times).
