Adnorm

Adnorm

In marketing, the readers of a publication who remember a particular advertisement, expressed as a percentage of readers who ordinarily would remember advertisements of a given type. For example, an adnorm of 50 means 50% of readers remember a given advertisement. An advertisement's adnorm is determined through market research. Adnorm is important because it can influence the success or failure of a marketing campaign.
