301 redirect from Castos / Seriously Simple Podcasting Plugin

After importing your RSS feed into Transistor, you’ll then need to redirect your old feed so that it points to your new Transistor feed.

Important: If you haven't imported your show yet, you should follow our Import Guide first.

Export your Analytics

It’s a good idea to export any analytics for your podcast at this point. Analytics do not transfer between hosts so it’s good to take a copy now for your own records.

How to redirect your feed from Castos to Transistor?

In your Transistor account, go to the Overview tab and copy your new RSS feed. You'll need this as part of the redirect process.

Each podcast host has their own instructions on redirecting a feed. For Castos and the Seriously Simple Podcasting plugin, you can refer to their guide here: https://support.castos.com/article/76-redirect-your-podcasts-rss-feed

Important: This redirect option is only used when you no longer want your WordPress site to host your RSS feed.
For WordPress users, Castos recommends the following steps:

Sign in to your Wordpress Admin Dashboard
Go to Podcasting > Settings > Feed Details
If you have multiple podcasts, select the title of the podcast you'd like to redirect
Check the box titled Redirect this feed to new URL
Paste your new Transistor feed into the New podcast feed URL field.
Click Save Settings

The redirect is now complete.

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 Castos 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 Castos 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 Castos 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 Castos?

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 Castos 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.
