Buying podcast advertising is not complicated. But it is very easy to spend the wrong money on the wrong shows and walk away wondering if podcasts actually work.
This guide breaks down the actual mechanics of how podcast ad buying works, what you need to decide before you spend a dollar, and where B2B companies tend to go wrong.
Before you contact any podcast network or platform, understand that there are two fundamentally different ways to buy podcast advertising.
Programmatic buying is the self-serve route. Platforms like Spotify Ad Studio, Acast Marketplace, and Podcorn let you set targeting parameters, upload creative, and run ads across a large inventory of shows. It is fast to launch, has low minimums (sometimes as low as $250), and scales easily. The tradeoff: less control over which shows run your ad, and your message is often dynamically inserted into the episode feed rather than baked in.
Direct buying means contacting a show or its sales team directly and negotiating a custom insertion. You pick the show, the episode, the placement (pre-roll, mid-roll, or post-roll), and the messaging. Most shows that do direct buying require minimums of $5,000 to $15,000+ per campaign. The tradeoff: more work upfront, but higher quality placements with host-read ads that feel native to the show.
For B2B, direct buying generally outperforms programmatic. The shows your buyers actually listen to are niche, targeted, and rarely available in mass programmatic inventory. More on that below.
Podcast ads are priced on CPM: cost per thousand impressions. Here is what rates look like in 2026 by placement type.
Pre-roll (15-30 seconds, before the episode): $15-$30 CPM for general audiences. Skews lower because many listeners skip forward.
Mid-roll (30-60 seconds, during the episode): $25-$50 CPM for general audiences. The premium placement. Mid-roll host-reads have the highest recall and conversion rates.
Post-roll (15-30 seconds, after the episode): $10-$20 CPM. Smallest audience, lowest conversion. Usually only worth buying as an add-on.
B2B and professional niche shows: $50-$100+ CPM. Smaller audiences that are precisely right for B2B products command premium rates. The math can still work because the audience quality is higher.
A useful back-of-envelope calculation: if a B2B software show has 3,000 downloads per episode and charges $70 CPM for mid-roll, one episode costs $210. A 10-episode run costs $2,100. That is not a large number for enterprise advertising. The question is whether those 3,000 listeners include enough of your actual buyers to make the spend meaningful.
For real reach at scale, plan to spend $10,000 to $25,000 minimum on a B2B podcast ad campaign. Smaller experiments can yield directional data, but should not be mistaken for a full test.
This is where most B2B buyers get stuck. Finding the right shows requires more than a keyword search on Spotify.
Start with your own listening. Ask your sales team, your best customers, and your leadership team what podcasts they actually listen to. The shows that appear repeatedly are your first list.
Use podcast directories with audience data. Podchaser, Listen Notes, and Chartable (or its alternatives) let you search by topic and filter by estimated audience size and demographics. Look for shows with consistent download counts, not one-episode spikes.
Check show media kits. Any show worth buying directly will have a media kit. It should include listener demographics, average downloads per episode, and audience verticals. If a show's media kit only shows social follower counts and no download data, that is a red flag.
Evaluate the host. For B2B, the host's credibility in your category matters. A host who is genuinely known and respected in your industry will have more listener trust than a generalist. That trust extends to the ads they read.
Aim for a shortlist of 5 to 10 shows at three tiers: one or two larger industry shows for reach, three to five mid-tier shows for efficiency, and one or two very niche micro-shows with small but highly targeted audiences.
Once you have your shortlist, find the buying contact. Shows typically fall into one of three categories.
Network-represented shows run through a podcast network's ad sales team. Networks like Wondery, iHeart Podcast Networks, Cadence13, and Slate handle negotiations centrally. Contact their advertising sales team through the network's advertising page.
Independently sold shows list an email or contact form for advertising inquiries. Many mid-tier B2B podcasts are independently run. Reach out via that contact, and expect a more direct conversation with the host or producer.
Platform-placed shows are available through marketplace platforms like Podcorn or AdvertiseCast, where you search available inventory and request placements without a dedicated sales rep.
When negotiating, ask specifically for:
Ask for a guaranteed episode count and lock in the pricing per episode rather than paying purely on CPM if the show's download numbers vary.
Host-read podcast ads perform significantly better when the host has clear direction, but authentic flexibility. Your brief should include three elements.
The core message. One benefit, stated plainly. Not five features. Not a product overview. One thing that will resonate with this show's audience and connect directly to your offer.
The call to action. Be specific and make it easy to say. A vanity URL (companyname.com/podcast) or a promo code makes attribution easier and gives the host something memorable to read. Avoid CTA instructions like "visit our website to learn more" with no specific URL.
Guardrails, not a script. Give the host the factual constraints (correct product name, accurate pricing if you mention it, required legal disclaimers) and then let them interpret it in their voice. Scripted ads sound scripted. The reason podcast ads outperform other audio formats is because listeners trust the host, and that trust transfers when the read sounds genuine.
Send the brief at least one week before the recording date.
Podcast advertising attribution is imperfect, but you need to measure something. Set up your attribution approach before the first episode runs.
Vanity URLs are the most common method. A short unique URL (yourproduct.com/podcastname) redirects to your main landing page and lets you track traffic from that source. It requires a clean landing page that converts, and it only captures clicks, not listen-through conversions.
Promo codes work for products with a transaction component. "Use code PODCAST for 20% off" creates a clear attribution signal at the point of purchase.
Listener surveys ask new customers or trial signups "how did you hear about us?" with podcast listed as an option. Self-reported, but captures the longer attribution tail that vanity URLs miss.
Brand lift measurement is more sophisticated: running pre/post surveys measuring brand awareness and consideration in the target audience during the campaign window. Tools like Spotify's brand lift measurement or third-party brand tracking panels can do this at scale. It requires larger budgets to generate statistically significant results.
Set baseline metrics before the campaign: organic branded search volume, direct traffic, demo or trial request rates. Changes in these metrics during a campaign period, even if not directly attributable, give you a qualitative read on whether the channel is working.
This is the question most podcast ad guides skip. For B2B specifically, it is the most important one.
If your sales cycle is longer than 60 days, your deal sizes are large, and your buyers need to see you multiple times before trusting you enough to take a meeting, then paid podcast advertising has a structural problem. You are paying for impressions that you cannot trace to revenue in any timeframe that satisfies your CFO.
The alternative that many B2B companies are moving toward is owning the show rather than sponsoring someone else's. A branded podcast gives you the same channel, but the audience is your audience, the content reflects your brand, and the relationship compounds with every episode. Rather than paying $30 CPM to be 30 seconds of someone else's show, you become the show itself.
A B2B company that runs 12 episodes per year and follows a solid content repurposing workflow gets significantly more from each episode dollar than a company buying spots. The complete guide to B2B podcast content strategy walks through what that model looks like in practice.
If you are specifically evaluating whether to buy ads or invest in production, the detailed breakdown in a B2B podcast ROI and measurement analysis shows where the numbers diverge.
Every B2B podcast ad campaign should generate at least one piece of actionable learning.
Pull your attribution data and calculate a cost per lead (or cost per qualified conversation, if leads are too early in your funnel to be meaningful). Compare it against your other paid acquisition channels. The comparison should be honest: if LinkedIn ads generate MQLs at $150 and podcast ads generated conversations at $400, that may still be worth it if the podcast audience was higher quality. Or it may mean the channel is not right for your offer at this stage.
Save the media kit and contact information for shows that performed. Repeat buys are easier to negotiate, often come with better rates, and benefit from the compounding effect of audience familiarity with your brand.
If the campaign generated any useful content (listener questions, host commentary that resonated, unexpected audience segments) feed that back into your content strategy.
Podcast advertising can be a legitimate B2B acquisition channel with the right offer, the right shows, and realistic attribution expectations. It rarely works as a standalone channel. It works best as part of a broader B2B content program where you are meeting buyers in multiple places, including, ideally, a show you own yourself.
If you are considering that shift, the guide to launching a company podcast covers what that investment actually requires.
