How do you setup frequency capping correctly? For example: I have setup 3/24 frequency cap, that is 3 impressions per visitor within 24 hours. Now if the 3 impressions is delivered, it is obvious that the ad zone will be blank due to the fact that 3 impressions has been met. How will that help in increasing revenue? If the ad zone is blank then it means no more impressions and no more impressions means no money. Can anybody help me with this? Thank you so much in advance.
