Switching an existing podcast from another hosting platform to Spreaker consists of two steps:
1 - Moving your old episodes to Spreaker by using the RSS importer. If episodes are already hosted on another podcasting platform, it is possible to move episodes via the RSS importing function. You simply need to copy and paste the RSS feed URL from your current hosting platform into the Spreaker RSS importer page.
2 - Forwarding your old RSS feed to the new Spreaker one. Once the importing is done, all of your episodes will be available to Spreaker’s community and can be distributed with the new Spreaker RSS feed. If your podcast is already available on platforms such as iTunes with your previous hosting and you don’t want to submit it again, it is possible to enable a redirection so you can keep your subscribers.
How to move your podcast from Anchor
Login to your Anchor account from a browser
Click on Settings on the top right corner and select Podcast Availability.
You will get here https://anchor.fm/dashboard/podcast/distribution .Next to Your RSS Feed, click on copy to get the the Anchor RSS URL in this format: anchor.fm/s/_______/podcast/rss
Now Access your Spreaker account or create a new one
Head to the CMS and click on Import Episodes
Paste your existing RSS URL copied from Anchor into the corresponding box and choose - or create - the podcast where your episodes will be uploaded in the next step.
Finally, you'll get in the RSS Importing Settings page where you can uncheck the “Import new episodes automatically” box and save.
Once this is done, all of your episodes will be moved on Spreaker. You can now set up a redirect from the Anchor RSS feed to the new Spreaker one. Access https://anchor.fm/dashboard/podcast/edit and scroll down until you see “Redirect URL”. Just paste your Spreaker RSS feed and click on “Redirect” and confirm it on the next window.
You can find your new Spreaker RSS feed by accessing the RSS Settings tab of your podcast, on the Content Management System (CMS): www.spreaker.com/cms/shows
Once the redirection will be set, click the link to your old Anchor feed. Do you get redirected to the new one on Spreaker? If so, you're done! Just wait for about two weeks: this way you can make sure all the podcatching platforms will update the RSS Feed. Then you can also delete your account and feed on Anchor.
