Websites usually use RSS feeds to publish frequently updated information, such as blog entries, news headlines, audio, video. RSS is also used to distribute podcasts. An RSS document (called "feed", "web feed", or "channel") includes full or summarized text, and metadata, like publishing date and author's name.Do I really need a RSS feed?
Yes , absolutely, 100%. An RSS feed is the only way an audience can access a podcast's content. Without an RSS feed, your podcast will not appear on your website or any podcasting directories, making it impossible for people to listen to it. Every podcast needs an RSS feed, there aren't any exceptions.
