Types of podcast cross-promotion
There are several ways podcast hosts collaborate, and each works differently depending on your goals and production capacity:
- Guest swaps — each host appears as a guest on the other's show. This is the gold standard because listeners hear the other host speak, building trust before they ever follow the new show.
- Ad swaps — each show runs a 30-60 second pre-roll or mid-roll ad for the partner show. Low-effort and scalable, ideal for shows with established ad slots.
- Trailer swaps — you play a short trailer or best-of clip from the partner show in your feed. Works well for introducing a show's tone and format.
- Shoutouts — a quick verbal mention during the episode. The most casual format, often used between shows that share a genuine relationship.
Finding the right podcast partner
Audience overlap is everything. The ideal partner podcast has listeners who care about your topic but aren't already listening to your show. Look for shows in adjacent niches — a startup marketing podcast pairs well with a founder storytelling podcast, not another marketing podcast covering the same ground.
When evaluating potential partners, check average episode downloads (ask directly — most hosts are willing to share), publishing consistency, and listener engagement (reviews, social mentions, community activity). A show that publishes weekly with 500 engaged listeners will outperform a dormant show with 10,000 total downloads spread across years of back catalog.
Making the pitch
When reaching out to a podcast host, be specific about the format you're proposing. Don't just say "let's collaborate." Instead, pitch a concrete idea: "I'd love to do a guest swap where I come on your show to discuss X, and you join mine to talk about Y." Include your show's stats, a link to a relevant episode, and why the collaboration would benefit their audience — not just yours.
Measuring results
Podcast attribution is notoriously difficult. Use a combination of strategies: create a unique URL or discount code mentioned in the episode, track download spikes on your show within 48 hours of the partner episode going live, and ask new listeners how they found you (in a welcome email or survey). Over time, the shows that consistently drive new listeners become your repeat collaboration partners — many successful podcasters maintain a rotation of 3-5 partner shows they swap with quarterly.
