Is Benecaster compatible with dynamic ad insertion?

Dynamic ad insertion (DAI) is a way of swapping different ads into an episode’s audio depending on when and where a listener downloads it — so a listener in Chicago hears a different ad than one in Austin, and an ad campaign that ended last Tuesday is replaced automatically rather than living forever in the file.

There are two main ways this is implemented, and they work differently with Benecaster.

Redirect-prefix tracking (Podtrac, Chartable, Spotify prefix, and similar): These services wrap your audio file URL with a short redirect — your episode’s URL in the RSS feed points to their server first, which logs the download and immediately sends the listener’s app to the actual audio file. Because Benecaster uses the URL you enter in the episode’s audio field as-is, this works transparently: enter the prefix-wrapped URL, and Benecaster includes it in every private subscriber feed. Your listeners’ apps follow the redirect chain normally and the ad service sees their real location for targeting.

Platform-level audio stitching (Megaphone, Acast, Omny, and similar hosting platforms): These services stitch ads directly into the audio at the moment of download, based on the listener’s location and the current ad inventory. The audio URL in your feed is their ad server’s endpoint, and that part works — your listeners’ apps hit the platform’s server and get the stitched audio. What doesn’t carry over is anything tied to the platform’s own RSS feed: per-subscriber engagement data, frequency capping, and download attribution in their reporting dashboard all depend on the platform serving the feed itself. Because Benecaster serves the private subscriber feeds instead, those platform-level analytics are unavailable. You’d be managing two separate download counts — Benecaster’s subscriber count and the platform’s audio request count — with no automatic reconciliation between them.

For most shows, Podtrac-style prefix tracking is the right tool and works without any special configuration. If you’re running a larger show with a direct ad sales relationship on Megaphone or a similar platform, reach out to support@benecaster.com before you set things up — the specifics depend on how your hosting provider handles audio delivery.
