Frequency Capping
Frequency Capping is a setting in advertising campaigns that limits how many times the same user sees an ad within a specific period of time.
Simply put:
don’t show the same ad too often to the same person
How Frequency Capping Works
The advertiser sets a limit, for example:
- no more than 3 impressions per day per user;
- or 10 impressions per week.
The system tracks the user (via cookies or identifiers) and stops showing the ad after the limit is reached.
Why Frequency Capping Is Needed
Frequency Capping helps to:
- avoid audience ad fatigue;
- reduce user irritation;
- improve advertising effectiveness;
- distribute the budget more evenly;
- increase reach by showing ads to new people.
What Happens Without Frequency Capping
If Frequency Capping is not used:
- a single user may see the ad dozens of times;
- effectiveness decreases;
- CTR and conversions drop;
- negative sentiment toward the brand grows.
How to Choose the Optimal Frequency
The optimal value depends on:
- campaign type (branding or performance);
- campaign duration;
- product complexity;
- funnel stage (acquisition or retargeting).
For example:
- for brand awareness — more frequent impressions (but with a limit);
- for retargeting — higher frequency, but carefully.
Related Metrics
- Reach — how many unique users saw the ad;
- Frequency — average number of impressions per user;
- CTR and conversions — help determine if effectiveness is declining.
Key Takeaways
Frequency Capping is a limit on the number of times an ad is shown to a single user.
It helps avoid audience fatigue, improve user experience, and increase the effectiveness of advertising campaigns.
