Podcasting is all about distributing digital audio content. Many companies or individuals record (and edit) their own podcasts. Once done, the recorded audio files are uploaded to an online host, usually a dedicated podcast host. When these files area available online, they can be distributed to popular podcast directories (Spotify / Apple Podcasts / Google Podcasts/ etc.) via the RSS feed. Listeners may want to subscribe to your podcast to know about future episodes and also visit your website to learn more about your podcast and hear the episodes there.
