Current Work

Registry and Payment ID

TAG’s Registration Working Group has developed an industry-wide TAG Registry that gives legitimate companies a powerful tool to help steer clear of criminal activity in the digital advertising supply chain. In the future, a Payment ID System will complement the TAG Registry and allow buyers of inventory to limit payments to legitimate actors only and thus eliminate all payments to illegitimate actors and criminals. TAG will enhance the Registration Program in the coming months to include secure APIs and features to streamline the on-boarding and vetting process.

Inventory Quality Guidelines:

The Evolved Guidelines Working Group updates and strengthens TAG’s Inventory Quality Guidelines (IQG) program, which aims to reduce friction and foster an environment of trust in the marketplace by providing a common framework to describe and disclose the characteristics of advertising inventory.  The IQG program has been expanded to include programmatic and native advertising buys. In addition, a series of disclosures that allow buyers to more transparent with sellers of ad inventory have been developed.
