Select Product Brand Taxonomy

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

Please note that the Custom option is only available in the PRO version of the Rank Math plugin. As you’re using the Free version of the Rank Math plugin, that’s why you’re not able to this option in Rank Math > General setting > WooCommerce > Brand.

However, you can use the following filter on your website to add any custom brand name in the Product Schema:

add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
    $entity['brand']['@type'] = 'Brand';    
    $entity['brand']['name'] = 'Rank Math';
    return $entity;
});

Make sure to replace Rank Math with your brand name.

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

Hope that helps and please don’t hesitate to let us know if you have any other questions.
 
Thank you.
