Ipm-Installs-Per-Mille

Description

IPM (Installs Per Mille) is a key mobile marketing metric that measures how many app installs are generated per 1,000 ad impressions—used to assess creative performance and ad quality.

Definition

IPM stands for Installs Per Mille (mille = thousand). It calculates how many installs an app receives for every 1,000 ad impressions served. It’s a core KPI in user acquisition (UA), especially for evaluating the effectiveness of ad creatives, targeting, and traffic sources. Formula:
IPM = (Number of Installs ÷ Number of Impressions) × 1,000

Why Is Ipm-Installs-Per-Mille Important for App Marketers?

IPM is a direct measure of how efficiently an ad creative converts views into installs. High IPM indicates strong creative resonance, good targeting, and quality traffic—factors that drive lower cost per install (CPI) and better ROAS. Ad networks and DSPs use IPM as a signal to determine ad ranking, delivery frequency, and bid competitiveness. A low IPM can result in poor delivery or rejection from top-performing channels. Marketers rely on IPM to test new creatives, compare campaigns, and optimize performance across different publishers and geographies.
