About Us


Trustworthy Accountability Group (TAG) is a first-of-its-kind cross-industry accountability program to create transparency in the business relationships and transactions that undergird the digital ad industry, while continuing to enable innovation. A joint marketing-media industry program, TAG was created with a focus on four core areas: eliminating fraudulent digital advertising traffic, combating malware, fighting ad-supported Internet piracy to promote brand integrity, and promoting brand safety through greater transparency. TAG was created by the American Association of Advertising Agencies (4A’s), Association of National Advertisers (ANA), and Interactive Advertising Bureau (IAB) and works collaboratively with companies throughout the digital ad supply chain.
