12 Best Podcast Advertising Platforms in 2026, Compared

Spotify Ad Studio is the self-serve front door to podcast advertising: you set a budget, pick an audience, upload or create an audio ad, and launch. Campaigns start at a $250 minimum budget in your local currency, and Spotify will produce the audio ad for you at no extra charge, including the voiceover. Ads run across Spotify podcasts and music, targeted by demographics, interests, genres and podcast categories.

The limit is reach. Your ad only plays to Spotify listeners, so a show's audience on Apple Podcasts or other apps never hears it, and host-read sponsorships still go through a Spotify sales rep. Buy Spotify Ad Studio when you want the fastest first test with the smallest budget; buy Acast or Libsyn Ads when you need host reads or reach outside Spotify.

AudioGo is SiriusXM Media's self-serve ad manager, and its pitch is breadth: one campaign buys audio ads across Pandora, Spotify, SiriusXM, iHeartRadio, SoundCloud, TuneIn and podcast apps. Campaigns start at a $250 minimum budget, with dynamic pricing that adjusts bids to marketplace demand. If you need an ad, a synthetic-voice version is free and a professionally recorded one costs $10, delivered in 48 hours or less.

The trade-off is control. Podcast inventory is one slice of a wider audio buy, and the CPM moves with the auction, so two identical budgets can buy different amounts of reach. Pick AudioGo when you want the widest audio reach from a single $250 test; pick Spotify Ad Studio when your audience lives on Spotify, or Acast when you want podcast-only inventory.

Acast is the world's largest independent podcast advertising network, with more than 140,000 shows and about 1 billion quarterly listens. Its self-serve ad platform runs pre-recorded ads and host-read sponsorships from the same dashboard, with targeting by gender, age, location, audience attributes and podcast category. Campaigns start from $500 on the platform, and Acast publishes its CPM ranges: $15 to $30 for pre-recorded ads and $25 to $40 for host reads.

The gap to watch is between the two buying routes. Self-serve starts at $500, while managed campaigns through the sales team typically need $10,000 to $15,000. Narrow targeting also lifts the CPM by about 20% per layer. Choose Acast when you want open-ecosystem reach with published rates; choose Spotify Ad Studio or AudioGo when $250 is your ceiling.

Buzzsprout Ads is the cheapest way into podcast advertising in this list: $100 buys 5,000 downloads of mid-roll promos, $200 buys 10,000, and $1,000 buys 50,000. You pick a podcast category, upload an audio clip of up to 40 seconds, and the promo runs as a mid-roll across Buzzsprout-hosted shows. It is built for podcasters promoting their own show, but any brand can buy the same inventory.

The limits are targeting and placement. You cannot pick individual shows, choose pre-roll or post-roll, or target by listener demographics beyond category. Buy Buzzsprout Ads when you want the cheapest possible test of podcast audio; buy Spotify Ad Studio when you need demographic targeting, or Acast when you want named shows.

Libsyn Ads is the marketplace formerly known as AdvertiseCast, rebranded in March 2024. It publishes the most detailed rate card in podcast advertising: 60-second host reads at $24 to $26 CPM, 30-second host reads at $18 to $22, dynamic back-catalog ads at $14 to $16, and programmatic at $12 to $15. You can research show inventory in the marketplace, then place the order with the sales team.

The catch is the floor. Shows need 20,000 downloads per episode to sell host-read inventory, and there is no published campaign minimum, so pricing is quoted per deal. The rate card is also undated. Pick Libsyn Ads when you want host reads with a visible price before the sales call; pick Acast when you want a self-serve route to similar inventory.

Podscribe is not a place to buy ads. It is the measurement layer that proves the ads you bought somewhere else actually worked. Its pixel-based attribution connects ad exposure to site visits and purchases, with IAB-certified counts. Pricing is a $250 monthly platform fee plus tiered usage: podcast impressions start at $1.50 CPM for the first 2 million a month, then fall to $1.35, $1.20 and lower as volume grows.

The fixed fee is the thing to budget for. A small test measuring 100,000 podcast impressions costs $150 in usage plus the $250 fee, so $400 for the month. Buy Podscribe when you need proof of return on a real campaign; skip it for a $100 test, where the fee costs more than the media.

Podbean bundles hosting with advertising, which makes it the cheapest host-plus-ads option here. Unlimited Audio costs $17 a month, or $12 a month billed annually, and includes the Ads Marketplace plus PodAds, its dynamic ad insertion service. PodAds lets you drop your own pre-roll, mid-roll and post-roll spots into old and new episodes, and you keep 100% of what you sell, paying only a $1 CPM serving fee.

The catch is geography. Podbean switched dynamic ad insertion off across Europe in March 2026, so listeners in the EU, the UK, Norway, Switzerland, Iceland and Liechtenstein hear no inserted ads. The Ads Marketplace also needs 1,000 downloads in 30 days and is US-only. Pick Podbean when you host on it already and sell your own sponsors.

RedCircle is built around monetization: hosting is the free front door, and the ad platform is the product. The Core plan costs $0 and includes unlimited hosting, storage and downloads for one podcast, plus access to the RedCircle Ad Platform, where brands buy host-read and programmatic ads on your show. Growth costs $19.99 a month, or $14.99 a month billed annually, and adds dynamic ad insertion, cross-promotion and instant payouts.

The real price is the revenue share. RedCircle keeps 30% of host-read ad revenue and 50% of programmatic revenue, plus 12% of subscription revenue, so a show that earns well pays far more than the subscription suggests. Choose RedCircle when you want to start free and sell ads at small scale; choose Podbean when keeping 100% of direct sales matters more.

Gumball, run by Headgum, is a marketplace for host-read ads where you pick the exact shows. You browse by category, keywords, air dates and audience, see each show's price, and check out with a card. Every booking carries per-episode category exclusivity, so a competitor cannot appear in the same episode. It also sells host-read ads on YouTube from the same marketplace.

The weakness is price discovery. Gumball publishes no minimum and no typical CPM, because each show sets its own price, so a ten-show campaign means ten different prices. Buy Gumball when you have specific shows in mind and want to book them yourself; buy Libsyn Ads when you want a published rate card to plan against.

Megaphone is Spotify's enterprise podcast ad server, and it sits on the other side of this list from the self-serve tools. Premium publishers run their ad operations on it: dynamic ad insertion across whole catalogs, host-read and auto-inserted formats, and programmatic access through the Megaphone Targeted Marketplace. Advertisers buy inventory that would otherwise need a direct network deal, with analytics from Spotify's publishing stack.

There is no self-serve route and no published price. Every engagement is quoted by the sales team, which puts Megaphone out of reach for a first test. Buy Megaphone when you are a publisher or a large advertiser buying premium inventory at scale; everyone else should start with Spotify Ad Studio or Acast.

Podsights is the attribution tool the largest podcast advertisers use to check whether their ads worked. It is now part of Spotify, and it uses pixel-based tracking to connect podcast ad exposure with site visits, purchases and brand lift. Because it sits outside any one publisher, a single dashboard can measure a buy spread across Acast, Megaphone, Spotify and direct deals at the same time.

Podsights sells no inventory and publishes no price, so it is not a starting point. It is the tool you add once campaigns are large enough that guessing at return on ad spend costs more than measuring it. Pair it with a buying platform from this list; on its own it buys nothing.

Audioboom is a podcast network that sells host endorsements on large, well-known shows. Its sales team places live reads, host endorsements and branded content, delivered in-file so the ad reaches the show's whole audience across every listening app, not just one platform. It has a strong UK presence alongside the US, which suits brands buying on both sides of the Atlantic.

Managed buys are quoted per campaign, and host-read minimums are set per show, so a small budget often does not clear them. The practical entry point is AudioGo, which offers a $250 self-serve route to Audioboom inventory among others. Buy Audioboom when you want a host endorsement on a big show; test through AudioGo first.
