A July survey by Oxford Road of 41 marketers representing $400 million to $500 million in podcast ad spend found 57% say measurement gaps are holding back investment. Oxford Road also released the AMP Accords, calling for unified podcast standards.

Why it matters

Podcast audience metrics are calculated differently across platforms, and marketers rely on a mix of promo codes, pixels, geo-testing, and media mix modeling to assess attribution. Oxford Road's proposed standards aim to address these inconsistencies.

Oxford Road's survey of 41 marketers found 57% cite measurement gaps as holding back podcast investment, while 40% said other channels deliver better returns. Whether the proposed AMP Accords will be adopted by platforms remains unclear.

The players

Oxford Road

Oxford Road is a media research and consulting firm that conducted the marketer survey and convened the Alliance for Measurement in Podcasting.

Alliance for Measurement in Podcasting

The Alliance for Measurement in Podcasting is an industry group convened by Oxford Road to develop unified podcast measurement standards.

The details

Oxford Road convened the Alliance for Measurement in Podcasting last year and this year released the AMP Accords, which call for a universal definition of a podcast, standardized cross-platform impression metrics, and a consistent approach to advertising attribution. Marketers also cited cluttered, repetitive ad breaks as a factor giving pause to investment.

Market Landscape

The AMP Accords extend an effort to standardize podcast measurement as podcasting competes for budgets against other digital channels. EMARKETER expects US advertisers to spend $3.76 billion on podcasts next year, up 10.4% year over year, which raises the stakes for consistent metrics.

Advertisers weighing podcast buys face inconsistent audience metrics across platforms, which complicates comparing returns to other channels. Standardized measurement, if adopted, could make podcast spend easier to evaluate against budget alternatives.

The takeaway

Before increasing podcast budgets, marketers should confirm how each platform counts downloads, streams, and views, and test attribution with promo codes or geo-testing. Consistent metrics would make these comparisons far more reliable.
