The interview with Neal Richter, Director of Science and Engineering at Amazon DSP, discusses the evolution and impact of IAB Tech Lab standards such as ads.txt, sellers.json, and SChain. These standards were developed to address issues of seller authentication and inventory misrepresentation in the digital advertising ecosystem. Ads.txt allows publishers to declare authorized sellers of their inventory, reducing fraudulent activities. Sellers.json provides a way for exchanges to list entities authorized to sell inventory, enhancing transparency for buyers. SChain adds a chain of custody to OpenRTB requests, ensuring the authenticity of the intermediaries involved. The adoption of these standards has been rapid, driven by the need for greater transparency and control in ad transactions. Challenges remain, particularly with in-app and CTV environments, but ongoing efforts aim to address these complexities and enhance the robustness of the digital advertising supply chain For more in-depth discussion of these topics and links to the news we discuss, subscribe to the Marketecture newsletter at https://news.marketecture.tv Copyright (C) 2024 Marketecture Media, Inc.
