Podbean supports multiple feeds in one pocast blog channel. You can have one feed per category, such as, a tech feed for all posts in tech category and a sports feed for all posts in sports category, etc. You can simply create a new category by clicking “Manage” -> “Categories” tabs in dashboard. Then you can do “Add New”. You may also quickly add a new category by click “categories” at the side bar of “Publish” page.
If you create a category “sports”, the RSS Feed URL of this category will be:
http://yourusername.podbean.com/category/sports/feed/
All posts in the sports category will be listed in this feed.
