Mercury’s Liam Heffernan: Downloads Don't Drive Podcast Success, Communities Do.

Mercury Podcast Network founder and CEO Liam Heffernan believes podcasting's biggest monetization opportunity isn't chasing millions of downloads. It's building communities around smaller, highly engaged audiences.

Speaking on the "PodBiz" podcast, Heffernan argues the industry has become overly focused on audience size while overlooking what ultimately makes podcasts valuable to advertisers and sustainable for creators.

"Building a community around your downloads is where the real money is," Heffernan says. "Downloads at face value are such a vanity metric because they only tell you a small part of the story."

His philosophy runs counter to an industry that often celebrates download milestones. Instead, Heffernan says a podcast reaching 20,000 to 50,000 monthly listeners with a clearly defined audience may offer greater commercial value than one generating millions of broadly distributed downloads.

"If you're doing a podcast that gets two million downloads a month, that sounds great," he says. "But how are you really going to sell that? Who's your audience? Who are you really speaking to?"

That audience-first approach shapes Mercury Podcast Network, the independent network Heffernan launches after identifying what he believes is one of podcasting's biggest blind spots: mid-sized independent creators.

"As a producer myself, I saw this gap in the industry where there was an awful lot of fantastic shows and creators who were doing amazing stuff," Heffernan says. "They deserved the opportunity to scale up and grow and monetize, but they weren't big enough to get the attention of the big networks."

Rather than compete directly for celebrity podcasts or blockbuster titles, Mercury is designed to support shows that have proven audiences but lack the infrastructure to grow. Heffernan says many of podcasting's largest networks naturally concentrate on the industry's biggest hits because they generate the highest revenues. But he questions whether those shows need network representation as much as smaller creators do.

"I had a bit of a bee in my bonnet about the fact that all of these big networks were fighting over the top 1% of shows," he says. "The shows that need the support of the networks are often the shows that get a bit forgotten."

For those creators, Heffernan says the biggest obstacles aren't talent or ideas—they're time, money and bandwidth.

"The biggest pain point of these mid-range indie creators, it's not the content. It's the time. It's the money. It's the energy," he says. "They're one-person shows. They're doing everything."

Removing those burdens, whether through advertising sales, promotion or operational support, gives creators more opportunity to focus on growing their audiences, he says.

Mercury's strategy reflects that philosophy. Rather than prioritizing short-term revenue, Heffernan says the network initially focuses on building credibility with advertisers and agencies. That led Mercury to launch Orbit, a companion platform designed to make network-level tools available to smaller podcasters that aren't yet ready for full representation. Orbit gives creators access to enterprise-level podcast hosting, advertising marketplaces, cross-promotion opportunities and other services for a monthly fee.

"We're trying to connect the dots in the industry and actually make the lives of independent podcasters cheaper, easier and better,” Heffernan says.

Heffernan's views on monetization are shaped in part by an earlier career in banking, where success revolves around financial analysis and numbers. Transitioning into podcasting requires abandoning that mindset.

"I came from a second life in banking and, you know, the mindset shift—because when you work in finance, it's all about the numbers,” he says. “So it was tough pivoting from that to an industry where I actually think it's quite detrimental to think numbers first. When you approach making a podcast or any content like that, you're setting yourself up to fail, because when you think about how to make the most money, what you're really thinking about is how to speak to everyone and no one at the same time."

That philosophy extends beyond advertising to Mercury itself.

"The success and monetization of our network is relational, not transactional," Heffernan says. "Long term, that's where the money is."

Looking ahead, Heffernan also sees podcasting evolving into a broader creator ecosystem where audio remains central but no longer exists in isolation. He points to Mercury's work with creators who are building brands across podcasts, social media and video simultaneously, saying networks increasingly need to support entire creator businesses rather than simply distribute audio.

"I think the line between talent representation and podcast network is increasingly blurred," he says. "We're entering an era where they're going to be one and the same."
