Affiliate Marketing platforms power performance-based partnership programs where publishers, content sites, coupon sites, and affiliate networks are paid for measurable outcomes — clicks, leads, sales, or qualified revenue. The category serves the B2C eCommerce and DTC affiliate-marketing buyer and is distinct from B2B Partner Ecosystem & PRM platforms (which live in Sales/RevOps). Core capabilities include affiliate recruitment and discovery, tracking and attribution (cookie-based, server-to-server), commission and payout automation across geographies, affiliate CRM, fraud detection, and reporting on partner-attributed revenue. The market includes enterprise eCommerce affiliate networks (Impact, CJ Affiliate, Rakuten Advertising, ShareASale, Awin), specialist eCommerce affiliate tools (Refersion, Tapfiliate, Post Affiliate Pro), and mobile-app-affiliate platforms (Tune, Trackier, Partnerize).
