Duplicate search results after feed redirect

App isn’t parsing redirect RSS correctly.

See LeicesterLife: A Gentleman’s World, shows the same podcast twice, but the Substack feed is redirected to Anchor. Anchor is where February episodes exist, not Substack. So the app is reading from the redirect but not figuring out that it’s the same as the Anchor one and consolidating results.

This sounds like the podcast creator did not properly migrate their feed. When the IDs of episodes match between the old and new feeds, AntennaPod recognizes that it is the same episode.

Additionally, AntennaPod performs some guessing: If the title is similar and the episode was released on the same day, it consolidates the episodes even when the podcast creator gave the episodes different IDs. So in this case, the podcast creator probably changed the ID and the title when moving to the new server.

So AntennaPod does even more than parsing the RSS correctly to avoid duplicated episodes. Unfortunately, some publishers mess up migrations so much that it becomes pretty hard to avoid duplicates.

“: If the title is similar and the episode was released on the same day, it consolidates the episodes even when the podcast creator gave the episodes different IDs. So in this case, the podcast creator probably changed the ID and the title when moving to the new server.”

Title is identical. It’s not about episode, it’s the whole show. It shouldn’t care if Host B changes IDs (the creator can’t control that) for individual episodes. It’s a redirected RSS feed. The destination is what matters; it shouldn’t even be able to see the original RSS source anymore.

When you’re migrating, all you can do is redirect the RSS to the new host. There’s nothing else you change – iTunes is going to key off the redirected data. And we’re assuming AntennaPod is keying off iTunes. Which means it should remove the erroneous one, because iTunes isn’t showing the show duplicated.

What should happen, is that AntennaPod gets redirected (that’s happening, because new episodes are showing for the new host) and when it gets to the destination, it says, “oh, this is the same destination as this other one I indexed myself” and only show one. It’s instead showing both as separate shows even though one is a redirect.

PodcastGuru doesn’t do this, it’s only AntennaPod from testing.

Aah, do you mean that the search function contains the same feed multiple times but with different URLs?

Correct.

It looks like it may have been temporary – it’s no longer showing the duplicate one as of today.
