What is a frequency capping?
This is an ad campaign setting that allows advertisers to limit a number of times a user sees ads. Thus, you can regulate the number of impressions to a unique visitor per 24 hours.
What is the best frequency cap?
By default, a limit of 3 impressions per 24 hours is set. According to statistics, this level is considered the most comfortable for site visitors without wasting your advertising budget. So this way your ads don't annoy users and you achieve maximum ad effectiveness.
It makes sense to increase the frequency cap in the following cases:
To maximize brand awareness.
Limited target or low market share.
Short campaign duration during high season, holiday etc.
