Cost Per Impression (CPI)

Definition

Cost per impression (CPI) is a metric used to determine the cost effectiveness of an advertising campaign, calculated by dividing the total cost of the campaign by the number of impressions generated. This metric allows advertisers and marketers to assess how much they are spending for each time an ad is displayed, making it easier to evaluate and allocate resources effectively. Understanding CPI is crucial for budgeting and resource allocation, as it influences decisions on where to invest for maximum visibility and impact.
