IAB Tech Lab: Ads.txt with Neal Richter
The MarketectureTV interview with Neal Richter, Director of Science and Engineering at Amazon DSP, examines the evolution and impact of IAB Tech Lab standards ads.txt, sellers.json, and SChain. These standards address seller authentication and inventory misrepresentation in programmatic advertising. Ads.txt enables publishers to declare authorized sellers to reduce fraud, while sellers.json helps buyers by listing entities authorized to sell inventory, increasing transparency. SChain introduces a chain of custody for OpenRTB requests to verify the intermediaries involved in ad transactions. The discussion notes that adoption of these standards has been rapid due to demand for transparency and control, but highlights ongoing challenges in in-app and CTV environments as efforts continue to strengthen the digital advertising supply chain. Recording date cited as May 2024.

IAB Tech Lab Defends ads.txt Against adagents.json Proposal
IAB Tech Lab's Senior Director of Programmatic, Hillary Slattery, published a rebuttal to a proposed 'adagents.json' standard, arguing that the existing ads.txt, sellers.json, and Supply Chain Object specifications already provide comprehensive supply path validation. She refutes claims that ads.txt lacks property identification, country-level authorization, and direct path marking, noting these are supported via OWNERDOMAIN, sub-domains, and DIRECT/RESELLER fields. Slattery warns that a new unverified standard could disrupt the ecosystem and emphasizes the importance of dual-verification for DSPs to block unauthorized sellers. She encourages industry collaboration through the Programmatic Supply Chain Working Group and highlights Jounce Media's research showing 98% of bid streams enable independent validation of directness.
OAAA Launches Programmatic Center of Excellence for DOOH
AI is pushing advertising back into physical spaces due to declining trust in online content, the rise of AI answer engines that bypass websites, and the growth of agentic AI. Out-of-home (OOH) and digital out-of-home (DOOH) advertising are gaining renewed relevance, with US OOH revenue up 10.7% YoY to $3.16B in Q2 and DOOH up 18.5%, representing nearly 40% of category revenue. To guide this evolution, the OAAA has launched a Programmatic & Automation Center of Excellence led by COO Patrick Dolan, focusing on standardization, workflow automation, agentic AI, reporting/attribution, and omnichannel/retail media integration. The initiative aims to automate both programmatic and static OOH processes, addressing friction points. However, this trend raises concerns about consumer opt-out options and the over-commercialization of public spaces, as noted by Ezra Klein.
Publishers Turn GEO from Experiment into Business
Publishers are increasingly monetizing Generative Engine Optimization (GEO) as a branded content offering, with companies like Future, Ziff Davis, Time, and several European publishers securing clients and revenue. Future's GEO product has over 30 clients and renewals, while Ziff Davis reports multiple clients. Time's offering involves placing brand messages in markdown files read by AI agents, despite Perplexity's initial pushback. Publishers see GEO as a premium opportunity to capitalize on AI-driven discovery, though measurement and longevity remain concerns. The IAB is developing a framework to standardize AI advertising measurement. Publishers are guarded about revenue figures due to competition, but the overall sentiment is optimistic, with GEO perceived as a real commercial opportunity rather than a defensive play.
