One of the promises of online advertising is the ability to put a maximum cap on the frequency of impressions per user to avoid excessive repetition. Digital campaign delivery is often extremely skewed, with some users receiving far too many impressions associated with the same campaign.
This research aimed to answer the following questions:
1) Do ad impressions deliver any impact beyond a certain level? When does frequency become ineffective or counterproductive?
2) What is a safe frequency threshold that we can use, beyond which we can consider an impression practically worthless?
3) Given such a guideline, how much wasteful spending can advertisers avoid?
