How Podcast RSS Feeds Work: The Technical Guide

Every podcast is distributed through an RSS feed. Here is how it works.

An RSS feed is an XML file hosted on the podcast's website. It contains:

- Channel metadata: show title, description, artwork, author

- Episode entries: each with a title, description, publication date, and an enclosure tag pointing to the audio file URL

The `<enclosure>` tag is the key element:

```xml

<enclosure url="https://example.com/episode1.mp3"

length="12345678"

type="audio/mpeg" />

```

Podcast apps read this RSS feed, download the audio file, and play it. The feed URL is what you "subscribe" to.

**Why this matters:** RSS is open and decentralized. Any podcast app can read any feed. You are not locked into a platform — if a show leaves Spotify, you can still listen via its RSS feed in any app.

podcast.5l5l.net discovers podcasts by reading these RSS feeds and indexing their metadata.
