Adding breadcrumbs on specific pages

Hello,

Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.

I tried checking the URL you wish to share but I was blocked. Can you please share those links directly in the Sensitive Data section instead?

With that said, I have modified the code for “Breadcrumbs COMPRAR ARTE” in the snippet plugin.

I went ahead and targeted the child page using the ID (as part of an answer to your question). Please refer to this code:

// Retrieving the Page ID:
global $post;

// Example Usage
if($post->ID === 4740){
    ...
}

Modified filter code:

add_filter( 'rank_math/frontend/breadcrumb/items', function( $crumbs, $class ) {
	global $post;
	if(get_post_type() === 'page' && false === is_tax() && $post->ID === 4740){  // Replace test_cpt with the CPT slug
		array_splice( $crumbs, 1, 0, array(array(
			"COMPRAR ARTE", // Replace with page name
			"https://rafaellozano.imkclientes.es/comprar-arte/", // Replace with page URL
			"hide_in_schema" => false
		)) );
	}

	return $crumbs;
}, 10, 2);

You can do the same for your Artists page.
