I recently read something that most of us know but nobody wants to admit: guest cross-promotion doesn’t really work as a growth strategy. And it’s worth saying clearly, because almost no podcast blog will.
The Myth And How It Spread
The idea goes like this: bring a guest on your show, they share it with their audience, their audience discovers you, and your numbers grow. It sounds like gravity. Every podcasting blog treats it that way. Most of us bought into it at some point. The problem is that it describes a mechanism that rarely survives contact with reality.
When a guest shares your episode, they usually post it to their social channels. Maybe an Instagram story, a tweet, a LinkedIn update. Their audience sees it, registers that their favorite person was on some show, and moves on. The post disappears in 24 hours. Nobody subscribes. There’s no bridge between “I enjoyed that guest appearance” and “I am now a regular listener of this show I’ve never heard of.”
The audience was there for the guest. Not for you. That’s not a criticism. It’s just how audiences work.
Content And Distribution Are Not The Same Thing
Here’s the distinction that gets collapsed in most conversations about guest episodes: having someone on your show as a compelling conversation is completely different from having someone on your show as a distribution channel. These are two separate propositions, and conflating them is where the confusion starts. Guests can bring excellent content. A great interview adds texture, credibility, and perspective that solo episodes can’t replicate. The right guest can challenge your thinking, bring expertise you don’t have, and create an episode that serves your audience well for years. None of that is mythological. All of that is real.
What’s mythological is the distribution promise. The idea that a guest with a large following is going to funnel a meaningful percentage of that following onto your show. That almost never happens, and when it does, the numbers are modest.
When Cross-Promotion Does Work
There is a version of guest cross-promotion that produces real results. It just looks different from what most people expect. The variable that matters most isn’t the size of the guest’s audience. It’s the overlap between their audience and yours.
A guest with 2,000 deeply engaged followers in your exact niche will almost always outperform a guest with 200,000 general followers. The reason is simple: those 2,000 people were already looking for something like your show. The content overlap is high, the trust transfer is high, and the conversion rate, though still modest, is real. They weren’t just there for the guest. They were there for the conversation, and your show is exactly the kind of place they were already trying to find.
Size without overlap is just noise. Overlap without size is quietly effective.
What Solo Episodes Do That Guest Episodes Don’t
Solo episodes with strong takes, clear arguments, and specific expertise tend to be more searchable, more shareable as standalone pieces, and more representative of what your show actually is. They’re also the episodes that most clearly build your voice and your relationship with your audience. A listener who finds you through a solo episode knows exactly what they’re signing up for.
Guest episodes can do this too, but they’re more dependent on the chemistry of a specific conversation. When that chemistry is there, it’s great. When it isn’t, you’ve spent a lot of production time on an episode that doesn’t really sound like you.
So Should You Still Have Guests?
Yes, but for the right reasons.
Have guests because they make good episodes. Because a specific conversation will genuinely serve your audience. Because the exchange of ideas produces something neither of you could have made alone. Because good conversations are good content, and good content is always worth making.
Don’t have guests because you’re hoping their audience will follow them over. Don’t spend weeks optimizing for cross-promotional potential from people whose followers have no particular reason to care about your show. Don’t measure the success of a guest episode primarily by the spike in your first-week downloads. If cross-promotion happens, treat it as a bonus. If it doesn’t, you still made something worth making.
The Honest Version Of The Advice
Most podcasting advice is written to be encouraging. That’s understandable. Starting and sustaining a show is hard, and people need reasons to keep going. But encouragement that isn’t honest isn’t actually helpful. It sends creators chasing strategies that don’t work, optimizing for numbers that won’t come, and feeling like they’re failing when actually they were just given bad information.
The guest cross-promotion myth falls into this category. It sounds like a growth strategy. It feels like one. It almost never is one. Have great conversations. Build your audience the slow way, through good work, consistency, and genuine trust. That’s the strategy that actually works. AND it’s a lot more fun.
