Move your podcast and episodes from another podcast host over to Castos.

Thinking of using WordPress along with the Seriously Simple Podcasting plugin to manage your podcast hosted on Castos? Jump to the second section to import your podcast into WordPress, then sync over to Castos.

Import your existing podcast into Castos


  1. From your dashboard, click Imports → Import A New Podcast.
  2. Enter your current podcast RSS feed URL. Castos will check if the RSS feed is valid or not. If the RSS feed is valid, you'll see Valid RSS feed URL. Click Next.
  3. The importer will show more details about your podcast and how many episodes it found ready to import from the RSS feed. Check the checkbox authorizing your permission to import it to Castos and click Next.

If you are expecting a different number of episodes, review our related guide here.

  1. After the import is complete, you can copy your Castos RSS feed to use on your previous RSS feed settings as a redirect, or go to your dashboard to begin managing your podcast on Castos.

Note on Imports: The amount of time it takes to import your podcast will vary from a few minutes to several hours depending on the number and length of episodes.

Redirect the RSS Feed from your previous host

This is the final step for changing your podcast's distribution and cannot be undone. Make sure episode files of your imported podcast are playing and all feed details are configured correctly before adding a redirect on your previous host's settings.

If your podcast is distributed from podcast directories, they still have your previous host RSS feed has your “podcast address”. A redirect lets all podcast directories know to start pointing to your Castos RSS feed for future updates. Redirecting the RSS feed to your podcast’s new feed in Castos is similar to having your mail forwarded to a new home address.

Users of Seriously Simple Podcasting will see they have two RSS feeds; one powered by Seriously Simple Podcasting and another from Castos. These are not connected but will be identical if feed details for both are configured.

Which one should you use?

  • Using your Castos RSS feed (like our integrations with Spotify and Amazon Music) will reduce bandwidth to your WordPress page when listeners and podcast directories crawl your RSS feed.
  • Using your Seriously Simple Podcasting feed will show episode URLs from your podcast on WordPress to podcast directories that support episode links. These can be added on Castos using custom links in episode pages on Castos.
  1. Return to the original host account and follow their steps for redirecting your podcast's feed to the new Castos RSS feed URL. This might be called redirect, new feed URL, 301 redirect URL, etc. by your previous host.
  2. Confirm the redirect has been added by entering your previous host's RSS feed into a browser like Chrome or Firefox. The URL will automatically redirect to your new Castos RSS feed.
