Add a media file prefix in Castos for Podtrac, Chartable, and other analytics or tracking services


Requires a valid Podtrac, Chartable, or other analytics tracking service prefix. You must be registered with these services before entering a prefix. Consult each third-party service's documentation for where you can find your media prefix. It is your responsibility to maintain your media prefixes and to ensure their validity. 

Services like Podtrac and Chartable provide an independent analytics service, which is sometimes required by advertisers as a uniform platform through which sponsors can level the downloaded numbers of the shows they support.

Adding the media file prefix will modify your RSS feed directly. We strongly recommend testing your episodes on podcast directories like Apple Podcasts, Spotify, and Stitcher to make sure everything works as expected. RSS updates can take several hours depending on the directory, so wait a couple of hours before testing.
