Cost Per Install (CPI)
What is Cost Per Install (CPI)?
Cost per install (CPI) is a performance-based pricing model where advertisers pay each time a user installs their app after clicking on an ad. The model is commonly used by mobile app developers to drive app downloads and is the dominant pricing model in mobile app advertising.
CPI is usually tracked as a key metric in mobile advertising, even if the advertiser is running a CPE or other type of ad campaign. By closely monitoring this metric, advertisers can optimize their campaigns and ad budgets to achieve better results.
