Bumper Bridges Gap in Untapped $1 Billion Podcast Advertising Potential with New ‘Bumper Score’

Bumper, a leader in podcast data and growth solutions, today announced the launch of the Bumper Score, an independent audience verification tool built to close the trust gap between podcast listenership and advertiser confidence. As ad spend continues to lag behind podcast consumption, the Bumper Score gives buyers and sellers a definitive, first-party data-backed currency to replace the fragmented, download-based metrics that have long held the industry back.

“Every advertising medium that has ever scaled to its full potential did so only after it solved for trust. Viewability unlocked digital display. Audited circulation unlocked print. Nielsen ratings unlocked broadcast. The pattern is clear and podcasting, the fastest-growing audio medium in history, has been waiting for its reckoning. The Bumper Score is the answer," said Jonas Woost, Co-founder at Bumper.

The podcasting industry currently faces a significant hurdle: millions of people are reached daily, yet advertisers lack a reliable way to prove it. According to 2025 research from Oxford Road, implementing better data and verification methods could unlock an additional $1 billion in ad spend for the industry.

The Bumper Score provides the proof the industry has been waiting for to unlock this investment opportunity by answering one question: how well does a show deliver ads to a verified audience? Scores range from 0 to 200, with 100 representing the industry average. Scores above this 100 benchmark signal stronger verified reach and higher value to potential sponsors.

“Measurement that brings more transparency and consistency to podcast advertising is a win for the ecosystem. Verified audience metrics like The Bumper Score give strong shows a clearer way to stand out, and help advertisers move faster and invest more confidently in the medium,” said Krystina Rubino, General Manager of Offline & Audio at Right Side Up.

To ensure accuracy, the score is calculated using first-party data from trusted sources, including:

• Podcast delivery data from hosting providers.
• Verified listener data from major podcast apps.
• Episode-level retention data to measure actual engagement.

Podcasters maintain full ownership of their data. While advertisers and agencies may request a show’s score, the publisher has total control over whether or not to share it.

“Audience verification leads to increased trust, confidence, and investment, and the Bumper Score is a catalyst for exactly that,” said Bryan Barletta, Partner at Sounds Profitable and President of Podcast Movement. “The Bumper Score gives the industry a shared language and the necessary infrastructure for audience quality that works for publishers, buyers, and the broader ecosystem. This is something that collectively, our whole industry has been working on for over a decade, but more impressively, the first time we’ve seen it presented in a way that publishers and buyers can realistically adopt and implement into their content growth and media planning strategies.”

While still in beta, advertisers including Understood.org and the Stupski Foundation are using the Bumper Score to inform spending decisions. To date, Bumper clients have allocated more than half a million dollars toward ad buys that are enabled by the Bumper Score.

The Bumper Score will launch as a free service in May 2026 as part of the Bumper Dashboard. Existing Bumper clients will receive priority access, with a waitlist now open for all podcasters.
