Unfortunately Red Circle does not currently give podcast creators the ability to add the Podcorn analytics prefix to their show's RSS feed.
Since many other hosting providers do support the Podcorn analytics prefix without issue, we hope that Red Circle will choose to support the our prefix soon.
Good news though! You can still use Podcorn to find sponsorship opportunities. You will just need to share a screenshot of your latest episode download numbers in your proposals, since Podcorn won't be able to verify your show's download numbers automatically through the prefix.
You'll also need to provide the brand with a screenshot of the episode's download numbers after 30 days, to show how many downloads the episode received.
If you have any further questions about your Red Circle account, you can reach the Red Circle support team here.
