Podcast hosting provides the audio hosting and RSS feed (basically a listing of all your episodes) for your podcast. Hosting companies upload your audio files, tell the podcast directories (e.g. Spotify or Apple Podcasts) your show’s details, and generate your feed. When a user subscribes to your podcast, the podcast host sends the audio files and media to respective directories directly. More feature-rich hosts also provide analytics, marketing tools, and other features to make publishing and growing your podcast easy.
