WordPress Custom Post Type RSS Feeds: Find, Fix and Auto-Post

Short answer: WordPress custom post types, such as events, listings, projects or recipes, can have their own RSS feeds. The address is usually https://example.com/feed/?post_type=event, or https://example.com/events/feed/ when the post type has an archive. The main /feed/ only includes regular posts by default, which is why custom content often never reaches social media. Once you know the right feed URL and have checked that it shows titles, descriptions, links and images, you can auto-post each content type to its own channels.

What custom post types are and why they matter for feeds

WordPress started as a blogging platform with two main content types: posts and pages. Custom post types, introduced in WordPress 3.0, let developers add their own types of content with their own fields and templates. Today they are everywhere:

• Events from event calendar plugins.
• Products in WooCommerce, which are a custom post type called product.
• Property listings on real estate sites.
• Job vacancies on recruitment sites.
• Portfolio projects, case studies and testimonials created by themes and page builders.
• Recipes, courses, podcasts and documentation from specialised plugins.

For many businesses, this custom content is exactly what they want to share: a new event, a new listing, a new vacancy. Yet it rarely appears in the site’s main RSS feed, so an auto-posting tool connected to /feed/ never sees it. The result is a social media presence that shows blog posts while the most commercially important content stays invisible.

How to find the RSS feed for a custom post type

WordPress offers several ways to reach a feed for a specific post type. Try them in this order and open each in a browser to see which one returns items:

1. Archive feed: if the post type has an archive page, for example /events/, its feed is usually at /events/feed/.
2. Query parameter: /feed/?post_type=event works on most sites for any public post type, even without an archive. Replace event with the post type’s internal name.
3. Taxonomy feeds: custom taxonomies have their own feeds too, for example /event-category/concerts/feed/, which lets you post only one category of events.
4. Plugin feeds: some plugins create their own feed addresses. Event and job plugins often document a dedicated feed URL.

The internal name of the post type is not always what you see in the menu. A post type labelled “Projects” might be called portfolio veya jetpack-portfolio. You can usually find it in the address bar when editing an item in the admin area, where the URL contains post_type= followed by the name.

If you only need the regular blog feed, our guide on finding your WordPress blog RSS feed link covers that. For shop products specifically, see the WooCommerce product feed guide.

Why a custom post type feed might be empty or missing

If the feed URL returns a 404 page, an empty channel or the wrong content, the cause is almost always in how the post type was registered. The key settings in register_post_type() are:

• public: if it is false, the post type is not queryable on the front end and will not appear in feeds.
• publicly_queryable: must be true for the query parameter method to work.
• has_archive: must be true, or a slug, for an archive feed such as /events/feed/ to exist.
• rewrite with feeds: controls whether pretty feed URLs are created. By default it follows the has_archive value.
• supports: if the post type does not support the editor or excerpt, the feed may contain titles but empty descriptions.

After changing registration settings, visit Settings, Permalinks and click Save without changing anything. That flushes the rewrite rules, which is often the missing step when a new feed URL returns a 404 error.

Other causes include security or caching plugins that block feeds, a setting in an SEO plugin that disables certain feeds, and page builders that store content in custom fields rather than the main content area, which leaves the feed description empty.

Adding a custom post type to the main feed

Sometimes you want one combined feed with blog posts and, for example, events. You can include custom post types in the main feed with a small code snippet in a site-specific plugin or the child theme’s functions.php file:

add_action( 'pre_get_posts', function ( $query ) {
    if ( $query->is_main_query() && $query->is_feed() && ! $query->get( 'post_type' ) ) {
        $query->set( 'post_type', array( 'post', 'event' ) );
    }
} );

The condition on post_type keeps specific feeds, such as /feed/?post_type=event, working as before. Test on a staging site first, and remember that changing the main feed also changes what existing subscribers and any connected tools receive.

In many cases, separate feeds are the better choice. They let you send events to one set of channels and blog posts to another, with different message formats and posting times. That flexibility is lost when everything is mixed into one feed.

Getting images and useful text into the feed

The default WordPress feed includes the title, link, publication date, an excerpt in description and, if enabled, the full content in content:encoded. It does not include the featured image as a separate field. For custom post types, which often rely on a featured image and custom fields, that can mean the feed carries no picture and very little text.

Several approaches solve this:

• Rely on Open Graph tags. Many auto-posting tools, including PostRSS, can take the image from the linked page’s og:image tag. If your SEO plugin outputs Open Graph tags for the custom post type, the right image usually travels with the post.
• Add the featured image to the feed with a plugin or a small filter that inserts it at the top of the content or as a media:content element.
• Write proper excerpts. If the post type supports excerpts, fill them in. They become the description in the feed and often the text of the social post.
• Expose custom fields. Dates, prices, locations and other custom fields are not in the feed by default. You can add them with a filter on the feed content, or use a plugin that builds custom feeds.

If you use Advanced Custom Fields, auto-posting content with ACF fields explains how to bring field values into the feed text.

Checking a custom post type feed before auto-posting

Before connecting any automation, look at the raw feed and check each item for the following:

1. The feed returns HTTP 200 and valid XML, not an HTML page or a login screen.
2. Each item has a unique guid and a correct pubDate.
3. The link is a full URL to the item’s public page.
4. The description contains meaningful text, not an empty string or shortcodes.
5. An image is available, either in the feed or through the page’s Open Graph tags.
6. Items appear in the order you expect, usually newest first.

Event feeds deserve special attention. WordPress feeds are ordered by publication date, not by event date, so an event published today for next spring appears as the newest item today. That is usually what you want for announcements, but it surprises people who expect the feed to follow the event calendar. Running the feed through a validator catches structural issues; our list of RSS feed validators and debugging tools is a good starting point.

Common mistakes with custom post type feeds

Most problems with custom post type feeds come from a handful of repeat mistakes. Checking for them saves a lot of debugging later:

• Using the admin label instead of the internal name. ?post_type=Projects will not work if the registered name is portfolio. Always use the internal name.
• Forgetting to flush permalinks. A new archive feed often returns 404 until the rewrite rules are refreshed by saving the Permalinks page.
• Relying on a feed that includes drafts or private items. Public feeds only include published items, so content scheduled for later appears only when it goes live. That is correct behaviour, but it confuses people testing with unpublished content.
• Switching plugins without checking the feed. Replacing an events or portfolio plugin usually changes the post type name, which silently breaks any feed URL based on the old name.
• Mixing too much into one feed. A single feed with posts, events, products and vacancies makes it hard to send each type to the right audience and at the right time.
• Ignoring the item limit. WordPress shows ten items per feed by default, set under Settings, Reading. A site that publishes many listings at once may need a higher number so no item drops out before it is picked up.

After any change to plugins, themes or post type settings, open the feed again and confirm the newest item is the one you expect. It takes a minute and catches most breakages before your followers notice.

Practical examples of custom post type feeds

A few common setups show how useful separate feeds can be:

• A venue or club publishes events as a custom post type. The events feed goes to its Facebook Page and a Telegram channel, while the blog feed goes to LinkedIn.
• A real estate agency publishes listings. A taxonomy feed for “for sale” goes to one set of channels, “to rent” to another.
• A recruitment firm publishes vacancies. The job feed goes to LinkedIn and X, while company news stays on the blog feed.
• A design studio publishes portfolio projects. The project feed posts to Pinterest and Behance-style audiences, while articles go elsewhere.
• A software company uses a changelog post type. The changelog feed goes to a Discord server and a team chat for customers.

In each case, the content type decides the channel. That is much easier to manage with one feed per post type than with one mixed feed and complex filters.

How PostRSS helps

PostRSS works with any RSS or Atom feed, so a custom post type feed can be added as a source just like a blog feed. It checks each source every 5 minutes, takes the image from the feed item or the page’s Open Graph tags, and posts to the networks you connect, with a message format you choose per target. You can add several feeds, one per post type or taxonomy, and use keyword filters for finer control. The official PostRSS WordPress plugin can also build the feed and create targets for you. See the features page for the full list of options.

The bottom line

Custom post types hold some of the most valuable content on many WordPress sites, but the main feed ignores them by default. Find the post type’s own feed with an archive URL or the post_type parameter, fix registration settings if it is missing, make sure images and text reach the feed, and connect each content type to the channels that suit it. Events, listings and vacancies then reach social media as reliably as blog posts.

FAQ

What is the RSS feed URL for a WordPress custom post type?

Try /feed/?post_type=name, replacing name with the post type’s internal name. If the post type has an archive, /archive-slug/feed/ usually works too. Open the URL in a browser to confirm it returns items.

Why does my custom post type not appear in the main WordPress feed?

The main feed includes only regular posts by default. You can add custom post types with a small filter on the feed query, or use the post type’s own feed instead. Separate feeds are often easier to manage.

Why does my custom post type feed return a 404 error?

Usually the post type has no archive, feeds are disabled in its rewrite settings, or the rewrite rules were not flushed. Save the Permalinks settings page once and try the query parameter URL as an alternative.

Why is there no image in my custom post type feed?

The default WordPress feed does not include the featured image as a separate field. Add it with a plugin or filter, or rely on Open Graph tags, which many auto-posting tools read from the linked page.

Can I auto-post only one category of a custom post type?

Yes. Custom taxonomies have their own feeds, such as /event-category/concerts/feed/. Use that feed as the source, or apply keyword filters in your auto-posting tool.
