Summary
Repeated ad exposure is a double-edged sword: it can help messages stick (wearin) or risk audience fatigue (wearout). This ARF Knowledge at Hand report reviews the latest evidence and finds that while true creative wearout is less common than once assumed, it can occur under specific conditions such as heavy short-term frequency or when there is poor creative quality. For advertisers, the key is knowing when repetition builds impact and when it backfires.
