Q: Is CPI a primary KPI?

CPI is a critical indicator of performance, but it should always be viewed alongside downstream metrics like ROI to ensure volume isn't coming at the expense of profitability.

What is CPI?

CPI (Cost Per Install) is the standard metric for mobile user acquisition campaigns. It tells you how much you spend for each user who installs your app — directly linking media spend to app growth.

Worked Example

A mobile app campaign spends $25,000 and drives 5,000 app installs. CPI = $25,000 ÷ 5,000 = $5.00 per install. Gaming apps often target $1–3 CPI; fintech apps may accept $20+ CPI if LTV is high.
