IAB Tech Lab

Industry-leading technical standards body for digital advertising

IAB Tech Lab is the technical standards-setting body of the Interactive Advertising Bureau (IAB), a global digital advertising trade association. Founded to develop technical standards, solutions, and best practices for the digital advertising industry, IAB Tech Lab serves as a critical infrastructure organization that enables the programmatic advertising ecosystem to function efficiently and transparently. The organization develops and maintains widely-adopted industry standards including ads.txt, app-ads.txt, sellers.json, OpenRTB, VAST, VPAID, and the Transparency and Consent Framework (TCF) for GDPR compliance. IAB Tech Lab operates as a non-profit consortium that brings together major technology companies, publishers, agencies, brands, and ad tech vendors to collaborate on technical solutions for the digital advertising industry. Rather than being a traditional commercial AdTech company, it functions as an industry utility that creates open standards and frameworks used by thousands of companies globally. Its work is essential to addressing challenges around ad fraud, brand safety, privacy compliance, measurement, and interoperability across the complex programmatic advertising supply chain.
