Cross-Promotion: The Highest-ROI Growth Tactic

Trailer swaps, guest spots and feed drops — borrowing other shows' audiences, ethically.

The landscape

When it comes to the mechanics of audience-sharing deals, the details matter. Here's what the evidence and practitioner experience point to:

• Cross-promo is the most efficient podcast growth channel: audiences already listen to podcasts; you're not convincing a new habit, just redirecting an existing one.
• Trailer swaps: exchange 30–60s trailers, each playing on the other's feed — zero-cost, trackable via download deltas.

What actually works

When it comes to the mechanics of audience-sharing deals, the details matter. Here's what the evidence and practitioner experience point to:

• Feed drops (publishing a partner episode on your feed) work for tightly adjacent shows — high-value but reserve for genuine fits.
• The size-matching rule: aim for shows within 3–10× your audience — too small moves nothing; too big ignores you.

Putting it into practice

When it comes to the mechanics of audience-sharing deals, the details matter. Here's what the evidence and practitioner experience point to:

• Find partners in adjacent niches, not competitors — true crime + forensic science, personal finance + tax strategy — overlapping listeners, different content.
• Track everything: unique promo links or survey questions tell you which partner shows actually send listeners — double down on them.
