The final step of creating a podcast is exactly what separates it from any other audio file you may find. Shows are distributed through podcast listing services and client applications that regularly check for new episodes.
Podcast episode audio files must be hosted online. This can be done using a file server, stand-alone website, or commercial podcast hosting service. An RSS feed must then be created so that new episodes are made available to podcast listing services. Feeds are often included in commercial hosting services, and many blogging websites can create feeds as well.
Podcast listing services, like Apple Podcasts, compile RSS feeds in a directory and allow individuals to search for and subscribe to specific shows. These listing services are available as apps on mobile devices or using internet browsers.
Podcast listing services require cover art when creating the show profile. Cover art images should be JPG or PNG files with a minimum resolution of 1400 x 1400 px and a maximum of 3000 x 3000 px.
Additional information and resources can be shared with podcast audiences using show notes or an episode summary. These are sometimes integrated into the show listing or posted on a website.
While not required, websites provide listeners with a resource to find contact information and show production details. Sites can also provide a forum for hosts and their audience to communicate.
