The new YouTube update lets podcasters on YouTube distribute their content easily using RSS Feeds.
When YouTube podcasters finish a new episode, they connect their RSS Feeds to YouTube Studio to sync new episodes.
All you must do is open YouTube Studio > Create > Submit RSS Feed.
If you already have podcast in your YouTube channel, then open YouTube Studio > Content > RSS Settings > Connect to RSS Feed.
Integrating your RSS Feeds to your YouTube Studio will allow you to expand your reach as a YouTube podcaster.
