Custom Post Type Not Appearing in Jetpack Sitemap

Hi @a1exus,

To add a custom post type to the Jetpack sitemap, you will need to use the jetpack_sitemap_post_types filter to add it manually. See the Jetpack developer reference for more details: https://developer.jetpack.com/hooks/jetpack_sitemap_post_types/

Hello Swish and thank you for your message, I really appreciate it!

now, I’ve added the following php code to wp-content/mu-plugins/custom-jetpack-sitemap.php file:

<?php
/*
Plugin Name: Custom Post Types in Jetpack Sitemap (MU)
Description: Adds "sponsor" post type to the Jetpack sitemap.
Version: 1.0
Author: ChatGPT
*/

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly.
}

function custom_jetpack_sitemap_post_types( $post_types ) {
    if ( post_type_exists( 'sponsor' ) ) {
        $post_types[] = 'sponsor';
    }
    return $post_types;
}
add_filter( 'jetpack_sitemap_post_types', 'custom_jetpack_sitemap_post_types' );

assuming the code is actually correct, how can one verifies that it actually _is_ working and my custom post_type got into sitemap?

Hi there,

Thanks for the additional questions.

To verify if your custom post type is included in the sitemap, you can check the sitemap file directly by visiting?https://youarebetter.com/sitemap.xml?in your browser. Navigate to the sitemap:?https://youarebetter.com/sitemap-1.xml?and look for entries related to your “sponsor” post type. If they appear, your code will work correctly.

I can see one already: https://youarebetter.com/sponsor/echo-hydrogen-water/, but please let us know if everything works correctly.

Thank you!

I checked my sitemap but don’t see my two new ACF post types.

$ cat ./wp-content/mu-plugins/custom-jetpack-sitemap-20250317.php
<?php

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly.
}

/**

 *
 * @return array List of valid public post types.
 */
function get_dynamic_sitemap_post_types() {
    static $cached_types = null;
    if ( is_null( $cached_types ) ) {
        $excluded_post_types = ['attachment', 'revision', 'nav_menu_item'];
        $all_post_types = get_post_types(['public' => true], 'names');
        $cached_types = array_diff($all_post_types, $excluded_post_types);
    }
    return $cached_types;
}

/**

 *

 */
function dynamic_jetpack_sitemap_post_types( $post_types ) {
    return array_unique(array_merge($post_types, get_dynamic_sitemap_post_types()));
}

/**

 */
add_action('plugins_loaded', function() {
    if ( class_exists( 'Jetpack' ) && method_exists( 'Jetpack', 'is_module_active' ) && Jetpack::is_module_active( 'sitemaps' ) ) {
        add_filter( 'jetpack_sitemap_post_types', 'dynamic_jetpack_sitemap_post_types' );
    }
});

Howdy @a1exus – sitemaps are usually updated every 12 hours, are you able to generate a new sitemap request on your end to see if those new custom post types are listed?
