What happened
The IAB has introduced 'The AI-Era Attribution Blueprint,' a new framework for measuring AI's role in conversions. It aims to provide a common method for advertisers, agencies, publishers, and AI platforms to claim credit for sales influenced or completed by AI. The blueprint classifies conversions as human-owned, AI-assisted, or AI-executed, and determines attribution based on who created intent, made the decision, and completed the purchase. It also addresses the challenge of thinning click and referral data as AI takes over more of the purchase journey. IAB's 2026 Outlook Study shows 45% of ad buyers consider comparing AI-driven and traditional journeys their top measurement challenge. The framework assigns different responsibilities to ecosystem players and emphasizes the need for evidence to support claims. It is designed to complement existing attribution systems and aims to establish a common vocabulary for AI-assisted conversions.
