Cost Per Install (CPI)

Cost Per Install (CPI) is a metric used in mobile app marketing that measures the amount an advertiser spends to have one person download and install their app. For example, if a company spends $1,000 on a campaign and 100 people install the app, the CPI is $10. This helps businesses evaluate the efficiency of their advertising efforts by showing how much they pay to gain each new user through app installation. CPI is important for budgeting, optimizing marketing strategies, and assessing the return on investment for app promotions.
