RadioEpisode

RadioEpisode is a direct Episode subtype for a single radio episode. It adds no properties of its own; use the inherited Episode vocabulary (episodeNumber, partOfSeries, duration, actor, productionCompany).

For podcast-distributed episodes, prefer PodcastEpisode which carries the associatedMedia/audio file relationships podcast apps expect.

Full example of schema.org/RadioEpisode json-ld markup

The markup is verified as valid with Rich Results Test from Google.

schema.org/RadioEpisode
<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "RadioEpisode",
  "name": "The listener who used an HTML comment as JSON-LD",
  "episodeNumber": 42,
  "datePublished": "2025-07-14",
  "duration": "PT42M18S",
  "partOfSeries": { "@type": "RadioSeries", "name": "Debug Drive-Time" },
  "actor": { "@type": "Person", "name": "Jane Xoo" },
  "productionCompany": { "@type": "Organization", "name": "Xoo Code Radio" }
}
</script>

Minimal valid version

The smallest markup that still produces a valid RadioEpisode entity. Use it as the floor. Reach for the advanced example above when you want search engines and AI agents to understand more about your content.

schema.org/RadioEpisode (minimal)
<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "RadioEpisode",
  "name": "The listener who used HTML comments",
  "episodeNumber": 42,
  "partOfSeries": { "@type": "RadioSeries", "name": "Debug Drive-Time" }
}
</script>

Google rich results this unlocks

RadioEpisode is a structural type. It does not produce a rich result on its own.

Its value comes from combining it with a primary type whose markup earns a rich result (Article, Product, Event, and so on). RadioEpisode becomes the trunk that the primary type branches off viamainEntityorbreadcrumb. Include it on every page as the backbone of your markup.

Common RadioEpisode mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.
