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 future stack is layered: agents act through protocols, transact through existing rails, respect privacy constraints, and earn trust through measurement and evidence.
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.
Standards pages
- Agent workflow
The open agent-to-agent advertising workflow layer: discovery, buying, creative, signals, accounts, governance, and measurement over MCP and A2A.
- Layer
- Agent workflow
- Main question
- How do agents express advertising tasks — briefs, buys, creative, signals?
- Example standards / bodies
- AdCP (AgenticAdvertising.org)
- Existing-rails agentic stack
IAB Tech Lab's umbrella for agents on the existing rails: AAMP buyer/seller agents that negotiate and book deals (overlapping AdCP at the deal plane), ARTF as in-bidstream runtime, Agentic Audiences as signal exchange, the Agent Registry as trust.
- Layer
- Agentic runtime & signal exchange
- Main question
- How do agents run on the existing rails — inside platforms, at auction speed, and through OpenDirect deals?
- Example standards / bodies
- IAB Tech Lab AAMP, ARTF, Agentic Audiences, Agent Registry
- Transaction rails
The transaction, video, deals, object, and supply-chain rails that modern and agentic advertising still depend on.
- Layer
- Core transaction rails
- Main question
- How are impressions, video, deals, and supply paths transacted and described?
- Example standards / bodies
- OpenRTB, AdCOM, OpenDirect, Deals API, VAST, ads.txt / app-ads.txt, sellers.json, SupplyChain Object
- Privacy & consent
Consent strings, platform APIs, deletion frameworks, privacy taxonomies, and browser / OS constraints that govern activation.
- Layer
- Privacy & consent
- Main question
- What may be collected, transmitted, activated, and deleted — and on whose choice?
- Example standards / bodies
- GPP, TCF, Data Deletion Request Framework, Privacy Taxonomy; platform constraints via Privacy Sandbox (most ad APIs being retired), SKAdNetwork / AdAttributionKit, ATT
- Measurement trust
Verification, accreditation, fraud, viewability, OM SDK, brand safety, and media quality controls.
- Layer
- Measurement & media quality
- Main question
- Can delivery, data, and inventory quality be trusted?
- Example standards / bodies
- MRC accreditation, viewability and IVT guidelines, OM SDK, TAG certification programs
- Research & evidence
The evidence layer behind advertising standards: ARF, MSI, CIMM, JAR, attention, MMM, incrementality, currency, and agentic measurement validation.
- Layer
- Research & evidence
- Main question
- Did it actually work, and is the method valid?
- Example standards / bodies
- 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. AdCP and AAMP both negotiate and book deals; the deal plane is shared, not a boundary. The split is ancestry (greenfield vs. retrofit), mapped in the AdCP vs AAMP essay.
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
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.
- Prebid vs TAM vs Open Bidding (2026)
- Prebid 10 → 11 Migration
- Prebid Defaults That Hold Up
- OpenAds vs Prebid: The Wrapper Schism
- Header Bidding Troubleshooting Tree
- Cross-RMN Measurement Comparison
- IAB Incrementality Guidelines, Decoded
- In-Store Measurement Standards, Decoded
- DOOH vs Traditional OOH Buying
- Composable CDP vs Reverse ETL vs Packaged CDP
Deep dives are implementation surfaces. They should be read with the core standards pages, not as isolated categories.
The rest of the agentic-advertising stack.
- Essay
The executable signal object the standards move across — intent, semantic meaning, provenance, policy, activation, and measurement in one container.
- Topic hub
Vector representations as semantic infrastructure — the payload AdCP signal discovery and IAB Agentic Audiences operate over.
- Live prototype
A live visual prototype for agentic advertising orchestration — how signals, identity, governance, creative, buying, and measurement could coordinate as agents.
From inside the working group.
No Fluff Advisory is the operator-led AdTech, MarTech, and data advisory founded by Evgeny (Ev) Popov in 2022 in Brooklyn, New York — an AdCP founding member co-leading the protocol's Signals & Measurement working group, operating a live registered agent, and the publisher of this site's essays and standards atlas.
