The industry's certification program for ad fraud prevention, brand safety, and supply chain transparency. TAG certification signals that a company has met defined standards for IVT filtering, payment ID compliance, and anti-malware practices. The program is voluntary and the certifications are self-attested against audited criteria. It is meaningful as a baseline signal when evaluating vendors, but not a substitute for independent verification of what's actually running in your campaigns.
