What does a 301 redirect do?

A 301 redirect for your podcast RSS feed is very useful when you move to a new podcast host. It ensures that any subscriber or podcast platform still using your Substack feed won’t be faced with a broken link. Enabling a redirect means that your existing subscribers will stay subscribed and podcast directories can continue to pick up your new episodes.

A redirect is like leaving a forwarding address. It lets anyone using your old feed know where you have moved to.

How long does a 301 redirect last?

Most podcast platforms provide a permanent redirect for free, even after you have closed your account with them.

How long does it take to enable a 301 redirect?

A redirect should be active within a couple of minutes of it being applied to your Substack feed. Podcast directories will then be able to pick up your new episodes from Transistor the next time they check your feed. That’s usually within 24 hours of your redirect being active.

How to test if a 301 redirect is working?

If you visit your Substack feed link in a browser, it should automatically redirect to your Transistor RSS feed.

What happens if I don’t forward my old feed from Substack?

If you choose not to redirect your podcast, you may need to complete a few extra steps.

Without a redirect existing subscribers won’t know where you have moved to. They will need to manually re-subscribe to your new Transistor podcast feed. So be prepared to share your new feed out manually to regain your subscribers back.

Without a redirect podcast directories like Apple and Spotify will still be using your old Substack feed. To fix that without a redirect you’ll need to manually go to those platforms and update the feed they are using for your podcast.
