When the episode count limit is reached, the oldest episodes at the bottom of the list may be omitted from the show on Google Podcasts.

Episodes that have no value will be sorted to the bottom (oldest) of the list. You should expect a maximum of about 400-700 of the most recent episodes to be available from the published feed, sorted by the value. Google Podcasts has an episode count limit, based on the published RSS file size.A note on feed availability: If your podcast's feed becomes unavailable after it has been crawled by Google, Google Podcasts will continue to serve the last crawled feed version for a few weeks, then stop serving it if the feed has not become available again.Read more about how Google manages podcasts with multiple feeds. If your podcast has multiple feeds, be aware that Google will try to group similar or identical feeds together and serve only one of them.Therefore you should be sure that, at minimum, the feed and the homepage, plus all audio file URLs in tags be using the same protocol (ideally HTTPS). If your feed or homepage is hosted at one protocol (HTTPS) but the linked resources are hosted at another protocol (HTTP), Google Chrome will display a click-through warning to users before loading those resources, or possibly not allow them to be loaded at all. The RSS feed and all episodes should be located either on HTTP or HTTPS. Use either HTTP or HTTPS, but not both.A majority of the episodes must be in any of the supported audio formats and have the proper file name extensions.You can check by visiting your feed in an incognito window. The feed and audio files should not require any authentication or be blocked to Google in any way.You must provide an image for your podcast.We also recommend some additional tags for a better podcast experience.

Some tags are not required to appear as a podcast in search, but are required to be eligible as a recommended podcast on Google surfaces. Feeds without all the required tags might not be indexed by Google. Include all the required podcast-level and episode-level tags.Google doesn't use all the RSS feed tags, but the examples on this page show the important ones. This RSS feed should be well-formed, and conform to the RSS 2.0 specification as much as possible.
