What is an RSS feed redirect?
An RSS feed redirect takes your existing RSS feed URL and redirects, or forwards, it to a new RSS feed URL. This is similar to having your mail forwarded to a new home address. In other words, until Apple Podcasts and other podcast directories have had a chance to update their system, we want them to be forwarded (or redirected) to your new RSS feed if they look to your previous RSS feed URL.
After redirecting your RSS feed, the directories will automatically update your show's RSS URL but this process can take time. We recommend leaving redirects in place for at least 4 weeks. If this is not possible, you may need to update your show's RSS feed URL manually at the podcast directories. You'll need to consult each directory's help documents for steps to manually update RSS feeds for existing shows.
