Can I track downloads of an episode of a podcast I was a guest on?

You can use a Baked-In SmartPromo to measure how many listeners downloaded your show after listening to an episode of a different podcast that you guested on. 

Both shows involved will need to have the Trackable analytics prefix set up before the episode is published. As long as both shows have the Trackable RSS feed integration set up you'll be able to create a baked-in SmartPromo.

Please note, you can only create internal Baked-in SmartPromos (Baked-in SmartPromos between podcasts within your own Chartable dashboard)
