If you are aiming to have your podcast heard by a public audience, distribution is an important consideration. Many podcast platforms require an RSS Feed for your podcast. An RSS Feed will allow updates to your podcast to be read and distributed by other websites. You'll need your own website or blog where the podcast episodes are published, or publish on a podcast host, to create an RSS Feed.
Remember to check the Terms and Conditions for podcast hosting. Some may require paid plans for certain features.
