In practice, a podcast can have more than one feed. However, before creating a new show in Google Podcasts, Google first checks whether a new feed describes a show that is already on Google Podcasts.When Google finds or is told about a new feed, it crawls the feed and creates an entry for the show in Google Podcasts where people can listen to the show on various listening platforms, such as the Google Podcasts app or Google Home, or any RSS-compliant podcast player.Publishers can also explicitly tell Google about new feeds (most podcast hosting services automatically tell Google whenever a new feed or episode is published). Google constantly crawls the web looking for RSS feeds the same way it crawls the internet to look for new or updated web pages.Therefore your RSS feed must be available to, and readable, by Google's crawlers. Additionally, listeners can subscribe on any podcast playback app to any podcast listed in Google Podcasts. Google Podcasts powers the discovery and playback of podcasts on many Google services, including the Google Podcasts app for Android and iOS, Google Home devices, The Google Podcasts website in the browser, and more.

Google Podcasts does not store your RSS feed or audio files, but rather points to the RSS feed and audio files that you have posted elsewhere. Google Podcasts is a podcasting directory this means that podcast listening apps and other podcast listening services use Google Podcasts to find podcasts and enable playback.
