Mobile Attribution platforms (Mobile Measurement Partners, MMPs) attribute mobile-app installs and post-install events to the marketing campaigns and channels that drove them — covering paid social (Meta, TikTok, Snap), search (Apple Search Ads), programmatic (mobile DSPs), and organic install paths. The category exists because mobile-app attribution requires specialized SDK integration with iOS and Android, deterministic-and-probabilistic matching of click-to-install events, and SKAdNetwork compliance post-iOS 14. Core capabilities include SDK-based install attribution, post-install event tracking, SKAdNetwork support and probabilistic modeling, fraud detection on mobile installs, deep linking and deferred deep linking, cohort and retention analysis, and ROAS reporting at the campaign level. The market is led by AppsFlyer (dominant cross-platform MMP), Adjust, Branch, Singular, and Kochava.
