Podcast Industry Bets New Standards Will Unlock $1 Billion In Ad Growth.

The podcast industry has taken its biggest step yet toward standardizing how audiences are measured across audio and video, with the Alliance for Measurement in Podcasting (AMP) releasing a comprehensive framework that supporters say could remove one of the biggest barriers to future advertising growth.

Known as the AMP Accords, the white paper is the culmination of roughly a year of work by an industry coalition assembled by podcast advertising agency Oxford Road. It proposes the first unified framework for defining podcasts, measuring audience exposure across platforms, and evaluating advertising effectiveness in an era when podcast consumption increasingly spans RSS feeds, YouTube, and connected TVs.

Supporters say the initiative comes at a pivotal moment for podcasting. As more creators embrace video distribution, inconsistent measurement standards have made it difficult for advertisers to compare audiences across platforms, creating uncertainty about campaign performance. Many podcasters blame that for slowing the flow of advertising dollars into the medium – even as listeners pour in. Oxford Road estimates more than $1 billion in advertising spending is at stake if the industry fails to establish consistent measurement standards.

"The hard part was never writing the framework. The real accomplishment was getting companies with competing interests to agree on anything at all," Oxford Road CEO Dan Granger says. "We're already seeing momentum toward a consistent definition of a play. The short-term challenges are real, but I'm convinced this work will lift every boat."

‘Eyes Closed’ Test

Unlike traditional podcast measurement, which has long centered on downloads, the AMP Accords proposes a broader framework built around actual audience consumption.

At the heart of the recommendations is a shared definition of what constitutes a podcast. AMP proposes what it calls the "eyes closed" test. If the content still functions as a podcast without watching the screen, it qualifies as a podcast whether it is distributed through RSS, YouTube or another platform.

The report also formalizes AMP's new consumption-based exposure metrics, first previewed last month. Under the proposal, a Podcast Play is recorded after at least 30 seconds of listening or viewing, regardless of whether the content is consumed as audio or video. The framework also establishes common definitions for Podcast Audience, Ad Impression and Ad Audience, creating a shared measurement language across platforms.

Rather than replacing download metrics overnight, AMP says the new measures are intended to complement existing reporting during a transition period, allowing publishers, platforms and advertisers to compare performance using common definitions while preserving downloads as a useful delivery metric.

"For years, the buy side and the sell side have argued about whether a 'download' equals a 'listen,' and how YouTube views should be counted alongside podcast downloads," Podscribe CEO Pete Birsinger says. "The AMP exposure framework finally gives the industry the answer it has needed: a single, consumption-based metric that can work across Spotify, Apple Podcasts, YouTube, and everywhere else."

Beyond audience measurement, the AMP Accords also introduces a standardized attribution framework designed to improve confidence in podcast advertising performance. The proposal recommends randomized holdout-group testing — the same sort of incrementality methodology widely used by major digital advertising platforms including Meta, Google and Amazon — to better isolate the impact of podcast advertising on consumer behavior. AMP says such tests could give advertisers greater confidence when evaluating podcast return on investment while making campaign performance easier to compare across platforms.

Adoption Begins

While the recommendations are voluntary, AMP says adoption is already underway. Spotify recently updated its definition of a podcast play to require at least 30 seconds of consumption, aligning with AMP's recommendation and providing an early indication that major platforms may be willing to embrace common standards.

The coalition also confirmed it will submit the AMP Accords to the Interactive Advertising Bureau for consideration and deeper technical review, a potentially significant next step because IAB standards often serve as the foundation for broader industry adoption.

Another notable development is confirmation that Google and YouTube participated in the effort alongside Spotify and other major industry stakeholders, reflecting growing recognition that podcast measurement must encompass both audio-first and video-first listening experiences.

Industry-Wide Collaboration

AMP was quietly formed in July 2025, bringing together podcast platforms, publishers, advertisers, creators, hosting companies and measurement providers. The coalition says its goal has been to create voluntary standards capable of working across both open RSS distribution and closed platforms without forcing companies to abandon their existing measurement systems.

"Podcasting is no longer defined by audio alone," says FlightStory CRO Christiana Brenton. “For too long, creators have been shortchanged by inconsistent measurement across formats, making it harder to demonstrate the full value of the audiences they've built and harder for brands to invest with confidence.”

The AMP Accords were formally introduced Thursday during Oxford Road's CAO Summit in Rancho Palos Verdes, CA. AMP says its work will now shift from developing the framework to encouraging adoption across the podcast ecosystem, beginning with discussions with the IAB and other industry organizations that could eventually help turn the recommendations into widely accepted standards.
