TL;DR: The Media Rating Council publishes standards that define how digital advertising impressions and viewability are measured. As agentic advertising scales, MRC guidance is evolving to address how automated deal negotiation intersects with established measurement requirements.

What the MRC Does

The Media Rating Council (MRC) is the US industry body responsible for setting and auditing measurement standards for digital advertising. Its standards define what counts as a viewable impression, how invalid traffic should be filtered, and how measurement data should be collected and reported.

For US buyers, MRC accreditation in a measurement vendor is a signal that the vendor's methodology has been independently audited and meets the MRC's requirements. MRC standards also shape what buyers can contractually require of their supply partners: campaigns contracted against MRC-accredited viewability definitions have a defined common reference point.

The Measurement Challenge in Agentic Advertising

Agentic advertising introduces a measurement complexity that does not arise in conventional programmatic buying. When a buy-side agent negotiates a deal with a sell-side agent, the deal parameters are captured in a bilateral record. However, the delivery of that deal, what actually runs against the agreed terms, still relies on ad serving, measurement, and verification infrastructure outside the negotiated deal layer.

The question for US buyers is how to verify that what was agreed in the agent-negotiated deal record matches what was measured and reported in their campaign management and attribution systems.

This is not a new problem. Discrepancies between contracted terms and reported delivery exist in conventional programmatic. What changes in an agentic model is the speed and scale at which deals are negotiated, which means the volume of potential discrepancies can increase unless measurement verification is built into the governance model from the start.

What MRC Guidance Addresses

The MRC has published working documentation addressing measurement considerations for automated and AI-driven advertising transactions. The core requirements for MRC-aligned measurement remain constant: viewability definitions, invalid traffic filtration, and independent third-party verification are not suspended because a deal was negotiated by agents rather than humans.

For buyers, this means selecting measurement vendors that are MRC-accredited regardless of whether the campaign was placed through conventional programmatic or an agentic marketplace. The deal negotiation layer and the measurement layer are distinct. Agentic infrastructure handles the former; measurement infrastructure handles the latter.

What Buyers Should Require

US buyers deploying agentic advertising should ensure that their agentic platform integrates with or supports connection to MRC-accredited measurement vendors. Specifically:

The deal record should include measurement parameters: which measurement vendor is authorised, what viewability standard applies, and how invalid traffic filtration will be handled.

The audit log should capture whether delivery was reconciled against the agreed measurement parameters at campaign close.

Any discrepancy between agent-negotiated terms and measured delivery should be documented in the deal record, with a defined resolution process.

Alkimi and Measurement

Alkimi's DealSheet captures the agreed deal terms bilaterally. This includes the ability to record measurement parameters as part of the deal governance framework. Alkimi does not replace MRC-accredited measurement vendors; it provides the deal record layer that US buyers need to verify that negotiated terms were honoured and that measurement was conducted according to the parameters both parties agreed.

For US buyers, the right posture is to treat agentic deal governance and MRC-aligned measurement as complementary requirements, not alternatives.
