Cost per install (CPI)

Cost per Install (CPI) is that delightful little metric which tells you how much you're shelling out every time someone graces your app with a royal download. Imagine it as the velvet-covered admission fee you pay just to get someone to walk through your digital front door via a smartphone tap. Spoiler alert: the costs add up fast, so keep your wallet on speed dial.

Cost per install (CPI) is a critical metric used in mobile app marketing and user acquisition strategies, representing the amount of money an advertiser spends to acquire a new user who installs their application. This metric is pivotal for assessing the efficiency and effectiveness of app marketing campaigns, as it directly correlates advertising spend with tangible results in the form of app installations. By optimizing CPI, marketers aim to maximize the return on investment (ROI) by allocating budget towards channels and strategies that yield the most cost-effective user acquisitions. Additionally, CPI is often compared against other performance metrics such as customer lifetime value (CLV) to ensure that the cost of acquisition justifies the long-term revenue generated per user.
