Oxford Road announces “ORBIT’s Top Performing True Crime Podcasts” – its latest podcast rankings based on actual sales results, drawing from $1.6 billion+ in campaign data across 500+ advertisers.

True Crime is the genre that started the podcasting boom with Serial. Historically, it also has the second-highest ad spend out of all podcast genres. But while Oxford’s data shows that True Crime is in the top 20% of genres for ad efficiency, these impressive top-line numbers hide a fact: True Crime isn’t a monolith. Formats vary, attracting different audiences with parasocial and paranormal content.

To get the most out of a hard-working genre, brands need to untangle the averages and get to the insights. Oxford’s latest ranking shows that, despite its success, the True Crime genre is still being underestimated.

The top findings:

• Performance at Scale: Across more than 65 podcast genres analyzed, True Crime is second only to Comedy in spend. But while Comedy performance covers the spectrum, True Crime as a whole ranks in the top 20% for efficiency. The real issue isn’t that brands aren’t spending here; it’s that they’re not going wide enough. Most advertisers test a handful of shows, see results, and either grow or stop based on a limited test. The nuance of this genre rewards those who explore it.
• Mind the Brand Safety Pricing Gap: True Crime has a reputation that raises brand safety flags for some advertisers. That caution doubles for high-performing shows with paranormal or horror-adjacent tones. The irony: that same genre stigma suppresses competition and keeps rates down, despite highly engaged audiences.
• Start with Trusted IP: Legacy TV Broadcast IP (Cold Case Files, 20/20, I Survived) tops the chart and offers a natural entry point for brands still warming up to the True Crime ecosystem. These shows carry name recognition that lowers the internal sell and raises audience trust. If this is “True Crime basecamp,” it might not stay affordable for long.
• Plan for Companionship: A full third of the top-performing True Crime shows use a companion format, where the host-audience connection is close, personal, and personality-driven. The biggest mistake advertisers make here is treating these like any other True Crime show in their buy. Give hosts more creative latitude in their reads, review those reads separately, and set rate expectations accordingly. The payoff is better performance and more cost-efficient creative.
• True Crime isn’t a Monolith: True Crime might be one genre, but it’s comprised of many sub-formats. Companion, Investigative, Broadcast IP, and Dark Crossover all have a place in the top 15 list.

“As a true crime listener, I don’t think of it as one genre; I think of it as multiple different listening experiences. I go to Rotten Mango for deep investigative journalism. I go to Crime, Conspiracy, Cults, and Murder for a fresh take I haven’t heard before. The shows I love aren’t interchangeable, and neither are the audiences. ORBIT finally gives advertisers a framework that reflects how listeners actually behave — and that changes everything about how you should be buying,” said Olivia Gerving, Oxford Road Strategic Operation Specialist.

Oxford’s Measurement Advantage

Findings were surfaced using ORBIT (Oxford Road Benchmark Intelligence Tool) – built on the industry’s largest index of podcast advertising performance data. The system measures actual customer acquisition costs, return on ad spend, and sales results from real campaigns. Oxford Road has processed more podcast advertising performance data than any other agency, creating an index that normalizes results across different advertiser goals and verticals.

For performance marketers, the tool enables advertisers to de-risk initial buys, optimize faster, and find high-performing shows before they become expensive.

Oxford Road will continue to release new ORBIT rankings monthly, covering categories including genre-specific performance, international markets, emerging shows, and vertical-specific results. Each ranking draws from Oxford Road’s proprietary database of campaign outcomes across podcasting, streaming audio, terrestrial radio, and creator-based video.
