# A Podcaster's Guide to RSS
<small>Archived from the [original](https://help.apple.com/itc/podcasts_connect/#/itcb54353390) in case of future link
breakage.</small>
<br>
An RSS feed contains all the metadata of a podcast. This information governs what listeners will see about your podcast
on Apples services: from the the show art, to whether a podcast shows up in relevant searches, to episode titles and
descriptions.
In order for a podcast to be listed on Apples podcast directory and show up within the Apple Podcasts app, a
corresponding RSS feed must be created, submitted on Podcasts Connect, and it must pass Apples validation (see
Podcaster Support for more information).
All metadata in an RSS feed is stored within element tags (here is a RSS Feed Sample for reference). Each tag is
applicable to either show data (contained within the <channel> tag) or episode data (contained within an <item> tag).
This guide will explain what data to include and how it should be structured.
Note: This page does not list all supported RSS tags, just the most important ones. If Apple deprecates RSS tags in the
future, podcasters will receive notifications in Podcasts Connect and newsletter.
The figure below depicts a “Show view” from the Apple Podcasts app, and and labels how <channel> tags map to show
information.

In the table below, Required tags must be present in your RSS feed or it wont pass validation to be listed in Apple
Podcasts. Recommended tags arent required but are highly encouraged because they provide useful information to users.
Situational tags are important in certain circumstances.

Make your title specific. A show titled <em>Our Community Bulletin</em> is too vague to attract many subscribers, no matter how compelling the content.</p><p>Pay close attention to the title as Apple&nbsp;Podcasts uses this field for search.</p><p>If you include a long list of keywords in an attempt to game podcast search, your show may be removed from the Apple directory.</p></td><td colspan="3"><p><code>&lt;channel&gt;</code></p></td></tr><tr><td colspan="3"><p>&lt;description&gt;</p></td><td colspan="6"><p>The show description.</p><p>Where <code>description</code> is text containing one or more sentences describing your podcast to potential listeners.

For example:</p><div class="CodeLines"><code class="CodeLine"> &lt;![CDATA[</code><code class="CodeLine"> &lt;a href="http://www.apple.com"&gt;Apple&lt;/a&gt;</code><code class="CodeLine"> ]]&gt;</code></div></td><td colspan="3"><p><code>&lt;channel&gt;</code></p></td></tr><tr><td colspan="3"><p>&lt;itunes:image&gt;</p></td><td colspan="6"><p>The artwork for the show.</p><p>Specify your show artwork by providing a URL linking to it.</p><p>Depending on their device, subscribers see your podcast artwork in varying sizes. Therefore, make sure your design is effective at both its original size and at thumbnail size. You should include a show title, brand, or source name as part of your podcast artwork. Here are additional <a href="https://podcasters.apple.com" class="URL" target="_blank">marketing best practices</a>. For examples of podcast artwork, see the Top Podcasts chart.

The figure below depicts a “Show view” from the Apple Podcasts app and labels how <item> tags map to episode
information. Its important to note that the `<itunes:type>` show tag listed above affects how episodes are displayed.
By default shows are categorized as episodic meaning the most recent episodes will show up first and the <pubDate> of an
episode will be displayed. If you specify your show `<itunes:type>` to be serial, which requires also
specifying `<itunes:episode>` numbers for each episode, then episodes will be listed oldest to newest.

Here are few more technical details on using RSS with Apple Podcasts:
Apple Podcasts accepts RSS 2.0 tags as well as some additional tags specific to Apple Podcasts.
When you use tags specific to Apple Podcasts, indicated by a leading <itunes:> prefix, you must add the following
namespace declaration as the second line in your XML:
```xml
