meta title problem

Hello,

I’m sorry to hear about the issues you’re facing. I can help you with that.

To change the “schema title” of the product, you can navigate to your WordPress Dashboard, then go to Rank Math SEO → Titles & Meta → Products. Here, you can set the Schema Type to WooCommerce Product and customize the schema title. Once done, remember to click Save Changes.

As for changing the “title” of the products belonging to a certain category and adding a word to the beginning of it, you can do this by editing the product name in WooCommerce. You can navigate to WordPress Dashboard → Products and click on the applicable product. Then, you can edit the product name and add the word “photo of” at the beginning.

I hope this helps! If you have any further questions or need additional assistance, feel free to ask.

Hello,

I added the following filter to your site, and now only the product title is used for the mainEntityOfThePage property:

add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
	if(is_product()) {
		$data['WebPage']['name'] = get_the_title();
		return $data;
	}
	return $data;
}, 9999, 2);

Please check and let us know if you need our assistance with anything else.

Hello,

Since modifying the mainEntityOfPage using the hook rank_math/snippet/rich_snippet_product_entity didn’t work at first, you can go ahead and stick with method A.

Let us know how that goes. Looking forward to helping you.

Hello,

In that case, please replace the filters shared before with the following ones:

add_filter( "rank_math/snippet/rich_snippet_product_entity", function( $entity ) {
	global $post;
        $term = get_the_terms( $post->ID, 'product_cat' );
        $term_id = wp_list_pluck($term, 'term_id');
        if(in_array('36', $term_id)) {
                $entity['name'] = 'Photo of '.get_the_title();
	        return $entity;
        }
	$entity['name'] = get_the_title();
	return $entity;
});
add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
        global $post;
	if(is_product()) {    
              $term = get_the_terms( $post->ID, 'product_cat' );
              $term_id = wp_list_pluck($term, 'term_id');
              if(in_array('36', $term_id)) {
                     $data['WebPage']['name'] = 'Photo of '.get_the_title();
	             return $data;
              }
		$data['WebPage']['name'] = get_the_title();
		return $data;
	}
	return $data;
}, 9999, 2);

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.

Hello,

To update the SEO title of the category, please use the following filter:

add_filter( 'rank_math/frontend/title', function( $title ) {
        global $post;
	if(is_product()) {    
              $term = get_the_terms( $post->ID, 'product_cat' );
              $term_id = wp_list_pluck($term, 'term_id');
              if(in_array('36', $term_id)) {
	             return 'Photo of '.$title;
              }
	return $title;
});

To update the title in the itemListElement property of the Breadcrumbs, use this one:

add_filter( 'rank_math/frontend/breadcrumb/items', function( $crumbs, $class ) {
	global $post;
	if(is_product()) {    
              $term = get_the_terms( $post->ID, 'product_cat' );
              $term_id = wp_list_pluck($term, 'term_id');
              if(in_array('36', $term_id)) {
	              $crumbs[count($crumbs)-1][0]= 'Photo of '.get_the_title();
				  return $crumbs;
              }
	return $crumbs;
}, 10, 2);

The filter will update both the Breadcrumbs and the Breadcrumbs Schema.

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
