In digital marketing, CPI (cost per impression) is an important metric that tells you how much money each impression (ad view) is costing you. Impression means that every time a user views an ad, whether they click on the ad or not, it counts as one impression.
Suppose you’re using ads on any platform, such as Facebook ads, Google ads, Instagram ads, or any other ad platform. In that case, CPI helps you understand your campaign’s efficiency and ROI (return on investment).
