Record Growth and Global Reach in Certification In 2026, TAG's certification programs achieved significant milestones, with a record number of seals awarded and expanded international coverage. The high proportion of multi-market certifications highlights how companies are prioritizing compliance beyond their primary regions amid evolving threats that transcend borders. Independent audits for the majority of seals further strengthen trust in the process, ensuring verifiable adherence to high standards across the digital advertising ecosystem.
Leadership in Accountability and Threat Mitigation TAG Certification has established itself as the industry's benchmark for responsibility and accountability. Recipients demonstrate ongoing efforts to safeguard the ad supply chain from fraud, malicious content, and opacity while promoting brand-safe environments. As threats in digital advertising continue to advance, TAG's programs have increased in sophistication to meet these challenges, recognizing participants for forward-thinking leadership.
"Across digital advertising and around the world, TAG Certification has become our industry's trusted badge for high standards and accountability," said TAG CEO Mike Zaneis. "The companies that have achieved TAG Certification are doing the vital and ongoing work required to keep our supply chain safe, transparent, and accountable, and their commitment helps protect the entire ecosystem. As the threats to digital advertising continue to grow and evolve, so does the rigor of our programs, and we commend this year's TAG Seal recipients for setting a new standard for responsible and forward-looking leadership."
"The record number of seals covering multiple markets is a testament to how seriously global companies are taking compliance, not just in their home markets, but everywhere they operate," said Todd Miller, VP Policy and Compliance at TAG. "Threats like ad fraud and malvertising don't stop at national borders, and neither does the impact of TAG Certification. For participants across the global supply chain, the TAG Seal provides a worldwide assurance of industry leadership and commitment to high standards."
