Standards & Protocols.

A practical map of the standards, protocols, rails, privacy constraints, measurement methods, and research layers behind modern and agentic advertising.

Agentic advertising does not replace the existing adtech stack. It sits on top of it. Agents need task protocols, real-time execution frameworks, transaction standards, privacy and consent rules, measurement trust, and research evidence.

The standards stack — agents act through protocols, transact through existing rails, respect privacy constraints, and earn trust through measurement and evidence. AGENTS ON THE OLD RAILS The chain a single piece of work travels: brief → protocol → transaction → consent → measurement → evidence → trusted decision. Brief Protocol Transaction Consent Measurement Evidence Trusted decision Agent workflow — AdCP, the task protocol agents use to express briefs, media buys, creative, and signal work. AGENT WORKFLOW AdCP — briefs, media buys, creative, signals as tasks Agentic runtime and signal exchange — IAB Tech Lab AAMP, ARTF, Agentic Audiences, and the Agent Registry: where agents run and exchange signals. AGENTIC RUNTIME + SIGNAL EXCHANGE IAB Tech Lab AAMP, ARTF, Agentic Audiences, Agent Registry Core transaction rails — OpenRTB, AdCOM, OpenDirect, the Deals API, VAST, and the supply-chain transparency files agents still transact through. CORE TRANSACTION RAILS OpenRTB, AdCOM, OpenDirect, Deals API, VAST, supply chain Privacy, consent, and platform APIs — GPP, TCF, deletion request frameworks, and the browser / OS constraints that govern activation. PRIVACY + CONSENT + PLATFORM APIS GPP, TCF, deletion requests, SKAdNetwork, AdAttributionKit Measurement, verification, and media quality — MRC accreditation, the OM SDK, TAG programs, viewability and invalid-traffic guidelines. MEASUREMENT + VERIFICATION + MEDIA QUALITY MRC, OM SDK, TAG, viewability and invalid-traffic checks Research and evidence — ARF, MSI, CIMM, and JAR: the layer that tests whether any of it actually worked. RESEARCH + EVIDENCE ARF, MSI, CIMM, JAR — incrementality, validity, causality Nine deep dives — retail media, clean rooms, outcome APIs, CTV and live events, sustainability, Prebid, video and mobile, DOOH, and audio — the operating environments where the six layers become operational. DEEP DIVES — OPERATING ENVIRONMENTS Retail media Clean rooms Outcome APIs CTV & live Sustainability Prebid Video & mobile DOOH Audio
Six layers, one chain: a brief travels through protocol, transaction, consent, and measurement before evidence can call the decision trusted. Below them, nine deep dives — the operating environments where the layers become operational.

The future stack is layered: agents act through protocols, transact through existing rails, respect privacy constraints, and earn trust through measurement and evidence.

Deep dives

Inside the layers.

The core standards map explains the main layers. These deep dives show how standards become operational in specific environments: retail commerce, clean rooms, outcome APIs, CTV, sustainability, Prebid, video/mobile, DOOH, and audio.

  • Commerce deep dive

    Retail / Commerce Media Measurement

    The IAB/MRC Retail Media Measurement Guidelines (January 2024), the in-store definitions and store zones (December 2024), closed-loop attribution and its limits, incrementality, and clean-room verification. Retail media is not just an ad channel. It is a measurement negotiation between media, trade, commerce, and finance.

  • Collaboration deep dive

    Data Clean Rooms, PETs & PAIR

    IAB Tech Lab’s Data Clean Room Guidance, PAIR activation, ADMaP attribution, the OPJA deprecation, privacy-enhancing technologies in plain language, and output policy. A clean room without output policy is just a safer room with an unsafe door.

  • Outcome deep dive

    Event & Conversion APIs and Outcome Signals

    IAB Tech Lab ECAPI 1.0, the named event taxonomy, payload and deduplication governance, consent metadata (gpp_string, gpp_sid, mmt_only), and what trustworthy outcomes mean for optimization. Agents should not optimize against outcomes they cannot trust, interpret, or audit.

  • Streaming deep dive

    CTV, Streaming & Live Event Advertising

    The CTV Ad Format Portfolio, the Live Event Ad Playbook and Concurrent Streams API, SSAI, the VAST CTV Addendum, OM SDK on CTV, device attestation, and household measurement. CTV is not just digital video on a bigger screen — it is an app, device, stream, household, and verification problem.

  • Sustainability deep dive

    Sustainable Media & Carbon Measurement

    The Ad Net Zero Global Media Sustainability Framework, the IAB Tech Lab Sustainability Playbook, supply-path emissions, methodology fragmentation, and the carbon-versus-effectiveness trade-off. Sustainable media is becoming a measurement and supply-path discipline, not a vague brand promise.

  • Execution deep dive

    Video & Mobile Ad Delivery Standards

    VAST, SSAI, SIMID, MRAID, OM SDK, SKAN, AdAttributionKit, Android Advertising ID, device attestation, and CTV / mobile execution. A deep-dive child of the six-layer map: the agent may plan the buy, but the ad still has to render in a player, run inside an app, pass measurement, respect platform rules, and survive verification.

  • Place-based deep dive

    DOOH & Place-Based Media Standards

    OpenRTB DOOH, venue context, screen loops, proof-of-play, audience estimation, location privacy, and place-based measurement. In DOOH, the impression is not just a screen — it is a place, a moment, a venue, an audience estimate, and a proof problem.

  • Audio deep dive

    Audio & Podcast Advertising Standards

    VAST for audio, DAAST legacy, podcast measurement guidelines, dynamic insertion, downloads, ad delivery, and attribution. In podcasting, delivery is not the same as listening — and listening is not the same as outcome.

  • Infrastructure deep dive

    Prebid & Header Bidding Infrastructure

    Open-source publisher monetization infrastructure for header bidding, Prebid.js, Prebid Server, Prebid Mobile, first-party data, consent, identity modules, floors, analytics, and seller-side execution. Prebid is not a protocol standard — it is the open-source publisher execution layer where many standards become operational.

Deep dives are implementation surfaces. They should be read with the core standards pages, not as isolated categories.

The map

How the layers fit together.

Agentic advertising will still depend on the old rails. Agents need workflow protocols, runtime standards, transaction objects, privacy constraints, measurement trust, and research evidence — six layers, each with its own question and its own standards bodies.

LayerMain questionExample standards / bodies
Agent workflowHow do agents express advertising tasks — briefs, buys, creative, signals?AdCP (AgenticAdvertising.org)
Agentic runtime & signal exchangeHow do agents run inside platforms and exchange signals at auction speed?IAB Tech Lab AAMP, ARTF, Agentic Audiences, Agent Registry
Core transaction railsHow are impressions, video, deals, and supply paths transacted and described?OpenRTB, AdCOM, OpenDirect, Deals API, VAST, ads.txt / app-ads.txt, sellers.json, SupplyChain Object
Privacy & consentWhat may be collected, transmitted, activated, and deleted — and on whose choice?GPP, TCF, Data Deletion Request Framework, Privacy Taxonomy; platform constraints via Privacy Sandbox (most ad APIs being retired), SKAdNetwork / AdAttributionKit, ATT
Measurement & media qualityCan delivery, data, and inventory quality be trusted?MRC accreditation, viewability and IVT guidelines, OM SDK, TAG certification programs
Research & evidenceDid it actually work, and is the method valid?ARF, MSI, CIMM, Journal of Advertising Research

Layer boundaries are descriptive, not official. Specifications, public-comment status, and platform API support change — validate current status against the primary sources listed on each page before implementation.
