Frequency capping limits how many times a single user sees your ad in a given time period. This is critical for popup campaigns.
Prevent Ad Fatigue
If a user sees the same popup too many times, they will start ignoring it or even get annoyed. Frequency caps keep your ads fresh.
Save Budget
Don't waste money showing the same ad to a user who already ignored it. Cap it to 1-3 impressions per day.
Improve Conversions
When users see an ad a limited number of times, they are more likely to click when they are actually interested.
