IAB Europe’s Updated Retail & Commerce Media Glossary - March 2025

We are pleased to present the latest version of our Retail & Commerce Media Glossary for March 2025, designed to bring clarity to the fast-evolving digital retail media landscape. We would like to thank IAB Australia who provided us with their Glossary which we have adapted for the European Retail Media Landscape. This resource serves as your guide to understanding and demystifying the key terms used within this sector.

This Glossary includes the latest pan-European definitions of Retail & Commerce Media in digital advertising. These definitions were first introduced in the IAB Europe 101 Guide to Retail Media and are also available in this one page overview. 

We’d like to extend our gratitude to the following IAB Europe Retail & Commerce Media Committee members for their contributions and valuable insights in reviewing and refining the definitions and the Glossary:

• Jason Wescott, IAB Europe Retail Media Committee Chair and Global Head of Commerce Solutions, GroupM Nexus
• Tim Abraham, Senior Director, Data Partnerships, The Trade Desk
• Yara Daher, Retail Media Consultant, IAB Europe
