How do I ensure my episode publishing workflow with a podcast hosting platform stays compliant with RSS requirements?

To stay compliant with RSS requirements in a podcast publishing workflow, treat RSS as the “source of truth” and make sure every published episode updates the feed in a valid, predictable way.

1) Make sure your RSS feed is valid

• Use the podcast platform’s built-in RSS generator if possible.
• Validate the feed regularly with:
  • Podbase RSS validator
  • Cast Feed Validator
  • Apple Podcasts validation checks
• Confirm the feed is:
  • Well-formed XML
  • UTF-8 encoded
  • Accessible via HTTPS
  • Returns proper HTTP status codes

2) Follow podcast RSS spec basics

At minimum, your feed should include:

• channel metadata:
  • title
  • link
  • description
  • language
  • copyright or author info if needed
  • itunes:owner, itunes:author, itunes:category if targeting Apple Podcasts
• Each episode item should include:
  • title
  • description or content:encoded
  • pubDate
  • guid
  • enclosure with:
    • file URL
    • file size in bytes
    • MIME type, such as audio/mpeg

3) Handle enclosures correctly

The enclosure is critical for podcast playback.

• Always provide a stable, downloadable audio URL.
• Make sure the file is publicly reachable.
• Do not change the enclosure URL after publishing unless necessary.
• Update length to match the actual file size.
• Use the correct MIME type, e.g.:
  • MP3: audio/mpeg
  • M4A: audio/mp4

4) Keep GUIDs stable and unique

• Every episode needs a unique guid.
• Once published, the guid should not change.
• If you republish or edit metadata, keep the same guid so podcast apps recognize it as the same episode.

5) Publish metadata consistently

Before releasing an episode, verify:

• Title is final
• Description is complete and safe for syndication
• Publication date is correct and in RSS-compliant format
• No invalid characters or broken HTML
• Any explicit content flags are correct if your platform supports them

6) Avoid invalid or unsupported feed changes

Common compliance issues:

• Removing past episodes unexpectedly
• Reordering items incorrectly
• Changing feed URLs without redirects
• Using relative URLs instead of absolute URLs
• Serving broken or expired audio links
• Publishing episodes before audio uploads are fully processed

7) Use proper redirects when moving feeds

If you change hosting platforms:

• Set up a 301 redirect from the old feed to the new one.
• Keep the old feed live for a transition period.
• Notify directory services if required.
• Ensure episode enclosure URLs still resolve properly.

8) Automate checks in your workflow

Before each publish:

• Validate XML structure
• Check required tags
• Verify the audio file exists and matches the enclosure metadata
• Confirm dates and GUIDs are unchanged where appropriate
• Run a feed validation test in staging

9) Be careful with updates after publication

If you edit an episode after publishing:

• Keep the same guid
• Avoid changing the enclosure unless the audio file truly changed
• If audio changes, consider whether the platform and apps will recognize the update correctly
• Update the feed’s pubDate only if your platform’s policy and podcast app behavior support it

10) Follow platform and directory rules

Different platforms have additional requirements:

• Apple Podcasts
• Spotify
• YouTube Music / Google Podcasts legacy behavior
• Amazon Music
• Podcast hosting platform-specific rules

Check:

• Artwork size and format
• Explicit content settings
• Episode numbering fields
• Category restrictions
• Minimum audio quality and file size limits

Practical workflow checklist

Before hitting publish:

1. Audio file uploaded and verified
2. Title, description, and artwork complete
3. GUID generated and stable
4. Enclosure URL reachable
5. File size and MIME type correct
6. Feed validates cleanly
7. Episode date formatted correctly
8. Feed accessible over HTTPS
9. No broken HTML or invalid characters
10. Test in at least one podcast app
