Squarespace does not currently support RSS feed URL prefixes, so you'll need to add the Podcorn prefix ( https://pdcn.co/e/ ) to each new episode in Squarespace as you publish them.
Squarespace provides full instructions for adding a prefix to an episode here.
After the prefix is added to a new episode, you should see episode analytics data in your Podcorn dashboard within 24 hours.
Note: You don't have to add the Podcorn prefix to all your previous episodes, only the ones you'd like to get analytics for moving forward.
