Shop page in sitemap two times

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

This happens if you assign a WordPress page as your shop page (archive of your products).

However, if you want to remove it from your product sitemap, you can use this filter on your site:

add_filter( 'rank_math/sitemap/post_type_archive_link', function( $archive_url, $post_type ){
    if($post_type == 'product') { //change to match the actual post type
        return false;
    }
    return $archive_url;
}, 10, 2 );

Here’s how you can add a filter/hook to your WordPress site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

Looking forward to helping you.
