CPI (Cost Per Interaction) is a digital marketing metric that calculates the cost incurred by an advertiser each time a user interacts with their advertisement.

Definition

CPI, or Cost Per Interaction, is a digital marketing metric that calculates the cost incurred by an advertiser each time a user interacts with their advertisement. This interaction could be a click, a view, a download, or any action that a user might take in response to the ad.

Usage and Context

The CPI metric is used extensively in the field of online advertising. It provides advertisers with a measure of how much they are spending to get users to interact with their ads. This is crucial for assessing the effectiveness of an ad campaign and determining whether the cost of running the ad is justified by the level of user engagement it generates. The CPI is calculated by dividing the total cost of the ad campaign by the number of interactions it generates.

In the context of mobile app advertising, for example, the CPI would be the cost incurred each time a user installs the app after viewing the ad. This would give the advertiser a clear idea of how much they are spending to acquire each new user.
