Audio Advertising


Getting Started

Complement your existing online and offline branding campaigns with audio advertising. Choozle provides access to programmatic audio-specific publishers like Spotify, Triton, AdsWizz, and TargetSpot. With our suite of features, you can target audio ads to relevant geolocations and custom audiences to drive a digital advertising campaign that gets your brand heard.

What Is Audio Advertising

Choozle sources audio advertising placements through two options: private marketplaces and open marketplace. You have the option to either run their ad with the open marketplace by targeting audio creative OR private marketplace (PMP) by applying an audio deal. For PMP Audio deals, we have a pre-negotiated library for each partner that includes details on placement, specific genres, playlists, demographic traits, and more. 

Unlike traditional radio advertising, programmatic audio advertising enables data-driven targeting to reach audiences that extend beyond display or video advertising campaigns. Using programmatic audio-specific publishers like Spotify, Triton, AdsWizz, and TargetSpot, your audio ad will be served in audio content like digital radio and music-streaming services. Some publishers allow for companion banners that are served alongside the audio ad while it's playing.

Below is an overview of features that are available for each audio-specific publisher.

Building Audio Ad Groups

After your audio creative assets are uploaded you will be able to add them to an ad group by following the below steps. 

  1.  Select AUDIO as the ad group creative type.

    • Open Marketplace Audio: Reach your targeted audience based on available audio ads inventory across audio publishers like, iHeartRadio, TuneIn and Entravision. Open Marketplace Audio is ideal if you are looking to keep CPMs low and have a broad audience. Currently, you do not have the option to select specific categories with Open Marketplace Audio. You can use site lists targeting to either target specific audio streaming services or block specific audio streaming services. More detail on this can be found in the App Targeting article.

Audio Advertising Best Practices


  • Audio: audio advertising placements through two options: private marketplaces and open marketplace. 

  • Audience: As a best practice, keep your ad group as open as possible by not layering on audiences (targeting everyone). If you do want to layer on an audience, make sure to use data segments that have a higher reach and include in-app inventory. We suggest using data segments from the following data brands: 42matters, 4INFO, NinthDecimal, Adsquare, AlikeAudience, Cuebiq, Ericsson Emodo, Factual, Grab, Gravy, GroundTruth, inMobi, Kochava, Lovoo (Europe), Mobilewalla, oneAudience, Pinsight, PushSpring, Scanbuy, Semasio (Europe), StartApp, Unacast, Valassis Digital, or Zeotap. 

  • Site/App list: Block lists can be used with audio ad groups, but target lists can limit your scale. However, you can use site lists to target specific channels on Triton.

  • Geolocation: For maximum scale, don't apply geolocation targeting below the designated market area (DMA) level. 


  • Base bid: If you are using an open marketplace in your audio ad group, your base bid should start between $3 - $8 depending on the targeting audience. If using a private marketplace deal in your audio ad group, your base bid should meet the price floor of the inventory deal that you'll be targeting (these floors can range from $3 to $24, depending on the format and environment).

Additional Options 

  • Frequency: Frequency capping isn't recommended, as it can hurt the scale of your ad group. If you would like to frequency cap, remember that audio performs better as a prospecting strategy, and keep your cap high.

  • Time of day: Keep your targeting open and refrain from applying bid factors to time periods.

  • Viewability and brand safety: Viewability measurement is not available for audio—keep in mind that audio ads are non-skippable. Brand safety features, while possible, will limit the scale of your ad group. 

Use Cases

  • Audio advertising is an ideal tactic for brands looking to reach a broad audience, particularly for telecom, CPG, and retail industries.
  • Audio advertising is best used for awareness campaigns with a reach goal since people tend not to click on audio ads.
