Podcast Cross-Promotion: How B2B Shows Grow Audience by Partnering with Other Podcasts
Podcast cross-promotion gives you a way to reach listeners who already spend time with shows related to your topic. For B2B podcasts, that can be far more relevant than promoting to a broad audience with little connection to your subject matter.
For instance, UK podcast network Goalhanger regularly runs short promotions for its other shows within its episodes, taking advantage of natural audience overlap between programs such as The Rest Is History and The Rest Is Politics.
Spotify reports that Goalhanger reaches around 50 million people each month and can trace listeners converting from these promos to other shows in its network.
Your B2B podcast may work on a much smaller scale, but the same principle applies. A well-matched partnership puts your show in front of people who already listen to podcasts in your space and are more likely to care about what you have to say.
At Content Allies, we’ve seen firsthand how the right cross-promotion partnerships can support a broader podcast marketing strategy.
In this guide, we’ll show you how to find the right podcast partners, pitch collaborations, structure cross-promotions, and track whether they are actually helping your audience grow.
What Is Podcast Cross-Promotion?
Podcast cross-promotion is a collaboration between two or more podcasts that promote each other to their respective audiences.
It helps each show reach new, relevant listeners by tapping into an existing podcast audience, ideally one interested in similar topics.
Cross-promotion can take several forms, like guest appearances, interview swaps, trailer swaps, episode swaps, ad swaps, host-read ads, newsletter mentions, social media promotion, and shared video clips (we’ll discuss all these in detail later in this guide).
Why Podcast Cross-Promotion Works Well for B2B Shows
B2B podcasts have a built-in advantage when it comes to cross-promotion: listeners already trust the hosts and shows they return to. That makes a recommendation from the right podcast partner more meaningful than a cold introduction.
Below, we’ve shared the main reasons cross-promotion works so well for B2B shows.
1. Builds Trust Through Association
Podcast hosts build familiarity with their regular listeners over time. When a trusted podcast host recommends another show, invites its host for a guest interview, or runs its podcast trailer, that recommendation gives the new podcast an immediate layer of credibility.
That trust is reflected in Nielsen's Podcast Brand Impact data, which found that 62% of podcast listeners described hosts as likable, while 42% described them as credible.
For a B2B brand, that trusted introduction can be far more persuasive than encountering an unfamiliar branded podcast through a conventional ad.
2. Reaches an Already Qualified Audience
One of the biggest advantages of podcast cross-promotion is that you aren't starting from zero. If you choose the right partner, you're reaching people who already listen to podcasts and already have an interest in the subjects your show covers.
Spotify's Podcast Fan Study found that 54% of listeners discover new podcasts by hearing about them on a show they already listen to. This makes recommendations from other podcasters one of the most commonly cited sources of discovery.
In the case of B2B podcasts, this audience qualification and relevance is even more important. B2B podcasts may not necessarily be about reaching a higher number of listeners, but the right mix of people. These podcasts typically target a narrow group of decision-makers or industry professionals.
Another B2B or thought-leadership podcast with a relevant audience can help you gain the right listeners.
3. Grows Without Relying Entirely on Paid Media
Paid ads can certainly support audience growth, but relying on them for every new listener can become expensive.
Cross-promotion gives you another distribution channel. Instead of purchasing impressions or clicks, two relevant shows introduce each other to audiences they have already built.
There is still a cost in time and resources. Guest appearances need coordination, clips need production, email and social promotion need planning, and host-read promos need to be recorded and placed.
When both shows bring a relevant audience and similar promotional value to the partnership, each can reach new listeners without paying for every impression, click, or listen.
4. Strengthens Your B2B Network
Cross-promotion can create value beyond listener growth. Each collaboration gives you a reason to build a relationship with another host, company, community, or industry expert.
A guest appearance or shared promotion can later lead to referrals, future guests, conference opportunities, co-created content, webinar partnerships, or introductions to other potential collaborators.
Over time, these connections can make your podcast a useful relationship-building channel within your industry.
7 Main Ways for Podcast Cross-Promotion
Podcast cross-promotion can take several forms. The right approach depends on how closely your audiences overlap, how much coordination both shows can commit to, and what you want the partnership to achieve.
Some tactics are designed to introduce each show to new listeners, while others create a deeper collaboration between hosts and brands.
Below, we’ll walk through seven practical ways to structure a podcast cross-promotion partnership.
1. Trailer Swaps
A trailer swap involves two podcasts running each other's podcast trailer in their feeds or episodes. This is one of the simplest forms of cross-promotion because both shows can use an existing audio/video asset without producing new content.
Trailers work best when they are short, clearly explain who the show is for, and give listeners a reason to subscribe.
You can place them as a pre-roll spot, mid-roll insertion, or even publish them as a standalone bonus item in the RSS feed.
2. Host-Read Recommendations
A host-read recommendation is more persuasive than a standard trailer because it feels personal.
Instead of playing a prerecorded ad, the podcast host briefly explains why they recommend the other show and what listeners can expect.
This is what we’d recommend for B2B podcasts. That’s because when it comes directly from the anchor, the recommendation feels more like professional word of mouth than an ad, which can make it more credible to listeners.
On Spotify, creators can also pin up to two shows in the ‘Host Recommendation’ section. That could also serve as a way to cross-promote.
3. Episode or Feed Swaps
With an episode swap, each podcast publishes a full episode from the other show in its own feed. This gives listeners a much deeper introduction than a short promo because they can experience the format, host, and subject matter firsthand.
A lighter variation is a feed swap in which selected episodes, bonus content, or previews are temporarily distributed via a partner's RSS feed. These arrangements work best between shows with very similar target audiences and should be clearly labeled so existing listeners understand why the content is appearing.
4. Promo Spot Swaps
Promo spot swaps are essentially ad swaps between two podcasts. Each show agrees to run a short promotional message for the other, typically using equivalent insertion points like a pre-roll spot for one pre-roll spot or a mid-roll placement for a similar mid-roll placement.
These swaps can be structured around a fixed number of episodes, impressions, or weeks. They are especially useful when both podcasts have comparable listener numbers, weekly downloads, and engagement rates, making the exchange relatively easy to value.
5. Interview Swaps
Interview swaps involve each podcast host appearing as a guest on the other's show. This approach isn’t as promotional per se because each person contributes useful expertise while naturally introducing themselves, their company, and their show to a new audience.
This is one of the strongest cross-promotional formats for B2B podcasting because it combines audience growth with networking and thought leadership.
Guest interviews can also generate transcripts, clips, audiograms, LinkedIn posts, YouTube Shorts, and Instagram Reels, extending the collaboration far beyond the original audio episode.

6. Collaborative Episodes
A collaborative episode goes further than a standard guest appearance. Two podcasters may co-host an episode, run a joint panel with industry experts, debate a topic, analyze a major industry development, or create a special series together.
This approach takes more planning, but it can create something neither show could produce alone. And it can be distributed collaboratively on Spotify or YouTube, too (Apple doesn’t yet natively support collaborative distribution).
Collaborative episodes also strengthen the relationship between cross-promotional partners and create opportunities for future webinars, conference appearances, or branded content.
7. Newsletter and Social Cross-Promotion
Podcast cross-promotion is really about strategic content creation. And that’s where newsletters and social cross-promotion come in. Partners can promote each other's shows through email newsletters, LinkedIn posts, TikTok videos, YouTube Shorts, Reddit, and Facebook communities.
This is particularly useful for B2B shows because a podcast's audience may extend well beyond its regular listeners.
Sharing podcast highlights, video clips, quotes, audiograms, or guest features across multiple channels increases visibility and can generate referral traffic back to the show's website, Spotify page, Apple Podcasts listing, or other podcast directories.
What Makes a Good Podcast Cross-Promotion Partner?
A strong cross-promotional partner doesn’t have to be identical to your show. In fact, the best partnerships may come from podcasts that serve a similar audience from a different angle.
Here’s what we look for when arranging such partnerships for our clients:
Audience relevance: A podcast whose listeners overlap with your target audience in terms of role, industry, interests, challenges, or buying influence.
Audience size and engagement: Decent listener numbers, average number of downloads, weekly downloads, listener retention, ratings and reviews, and engagement rates where available.
Topic alignment: The shows should cover complementary subjects so that a recommendation feels natural to listeners. A cybersecurity podcast, for example, may cross-promote effectively with a broader enterprise IT show even if their editorial focus is not identical.
Brand and editorial fit: The host's tone, production quality, values, guest selection, and overall reputation should align with the brand and editorial values. A collaboration creates an association between both shows, so the partner should be someone you are comfortable introducing to your audience.
Consistent publishing: Active podcasts with a reliable publishing schedule. A show that releases episodes consistently is more likely to have an engaged audience.
Where to Find Podcast Cross-Promotion Partners
When looking for cross-promotion partners, focus on shows whose listeners are likely to care about your content and whose hosts have a clear reason to collaborate with you.
A few places can help you find those potential partners:
1. Your Own Network
Start with the people already in your professional network. For B2B podcasters, that could be previous podcast guests, customers, partners, industry experts, conference speakers, agencies, and other B2B content creators.
This is the easiest place to start because some level of trust already exists.
For instance, if you’ve had another podcast host as a guest before, you can ask them for an interview or trailer swap, provided their audience interests you.
LinkedIn can also help you identify who in your network is actively podcasting.
2. Podcast Platforms and YouTube
Search Spotify, Apple Podcasts, YouTube, and other podcast directories for shows covering topics related to yours.
Use the same terms your target audience would search for, then review the shows appearing in relevant categories and search results.
To narrow down your options, look at recent episodes, guest lists, show descriptions, publishing frequency, video clips, and highlights. These can give you a clearer sense of the topics the show consistently covers and the audience it appears to serve.
YouTube can add another layer of insight because recent uploads, views, and comments can help you see how active and engaged the show's audience is.
3. Use Podcast Discovery and Analytics Tools
Podcast discovery platforms can make the research process much faster. Tools like Rephonic and Podchaser (and its user-created lists) allow marketers and podcasters to search for shows by topic, category, audience characteristics, guests, and other criteria.
These tools can also help you compare potential partners using data such as listener numbers, audience overlap, social following, ratings and reviews, and publishing activity.
What we love about both these tools is that they make it easier to find relevant shows. For instance, Rephonic’s 3D graph tool connects shows with similar audiences and topics.
4. Ask Your Existing Audience
Your existing listeners can also tell you which podcasts could be good options for cross-promotion.
You can ask through email, social media, LinkedIn, a listener survey, or directly on an episode: What other shows do you listen to regularly?
The answers could reveal which podcasts already share attention with your show.
That makes them particularly promising cross-promotional partners because the audience overlap has effectively been validated for you. Even a small number of recurring recommendations can uncover independent shows or niche B2B podcasts that might not appear near the top of major podcast directories.
How to Run a Successful Podcast Cross-Promotion
A successful podcast cross-promotion campaign should be treated like any other marketing partnership: choose the right partner, define the value exchange clearly, agree on execution, and measure what happens afterward.
1. Identify the Right Podcasts
Use different methods like networking, podcast discovery tools, or audience recommendations to build a shortlist of shows that reach a relevant target audience and have strong topic, brand, and editorial alignment with your own podcast.
Review recent episodes, guest profiles, listener engagement, publishing consistency, ratings and reviews, and any available audience or download data to further narrow down the choices.
2. Decide What You Can Offer
Before reaching out, determine what your podcast can contribute to the partnership.
In addition to the exact method for podcast cross-promotion, consider the value proposition. And think beyond listener numbers.
Your value may also come from a strong email list, active social media community, access to industry experts, or high-quality content creation capabilities.
Remember, the stronger and more specific your offer, the easier it is for another podcaster to see why the collaboration makes sense.
3. Pitch the Partnership
Keep the initial pitch personalized and concise. Explain why you think the two audiences overlap, reference something specific about their show, and suggest a clear cross-promotion.
For example, you might propose an interview swap because both shows cover complementary topics, or suggest a podcast trailer exchange across two upcoming episodes.
Make the benefit to the other show obvious and keep the amount of work required to evaluate the opportunity low.
4. Agree on the Promotion Details
Once both sides are interested, document exactly what each podcast will do.
Agree on the format, campaign dates, number of placements, insertion points, episode selection, calls to action, creative assets, and where listeners should be directed.
For ad swaps, specify whether placements will run as pre-roll, mid-roll, or post-roll spots and whether they will use prerecorded audio or a host-read ad. For social and email cross-promotion, agree on which platforms will be used, how many posts or sends are included, and whether both parties will create their own assets or work from shared templates.
It’s best to work out the details in a document.
5. Track Results and Decide What to Repeat
Treat cross-promotion efforts like other marketing campaigns. Measure the campaign to determine whether the partnership actually contributed to audience growth.
You can track changes in:
Downloads
Subscribers
Referral traffic
Website visits
Email sign-ups
Social engagement
Compare these metrics during and after the promotion to your usual performance.
Where possible, we recommend using dedicated landing pages, UTM links, promo codes, or podcast analytics to separate cross-promotion activity from normal growth.
Also look at listener retention rather than downloads alone. If new listeners arrive through a partner but continue listening to subsequent episodes, that is a much stronger sign of a successful collaboration.
Use those findings to refine future partnerships.
Repeat the formats and partners that deliver relevant, retained listeners, adjust campaigns that underperform, and gradually build a network of proven cross-promotional partners around your show.
How Can a Podcast Promotion Agency Help With Cross-Promotion?
A podcast promotion or marketing agency can make cross-promotion more systematic by helping you identify relevant shows, evaluate audience fit, manage outreach, coordinate campaign details, and track results.
An experienced podcast agency may also have existing relationships with podcast hosts, networks, and production teams. Those connections can make it easier to arrange guest appearances, trailer swaps, host-read promotions, and other collaboration opportunities.
For B2B podcasts, marketing services can also help when your internal team has limited time or promotion expertise. An agency can connect cross-promotion with the wider goals of your show, including brand awareness, thought leadership, lead generation, or account-based marketing.
Plus, they can track campaign performance and compare it with other promotional efforts. This gives you a clearer basis for making podcast marketing decisions.
