Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
The screenshot you shared doesn’t load from my end.
I checked your site and a number of products URLs and then only issues I see are warnings on recommended properties, check the screenshot I have added in the sensitive section.
Please note that Rank Math takes the schema data from your product pages automatically and turns it into Schema-ready content. Likewise, the aggregateRating and review fields are taken from your actual product reviews that your buyers/customers leave on your products.
Since you are using Judgeme to acquire reviews and ratings, you will need to have the ratings mapped to the product schema using this filter:https://rankmath.com/kb/filters-hooks-api-developer/#change-post-schema-data to get rid of the aggregateRating
and review
warnings.
To fix the brand
warning, head over to WordPress Dashboard > Rank Math > General Settings > WooCommerce
and choose from any of the available fields to use as your product’s brands.
If you want to use a custom value for your Brands, you can do that by using the following code in your theme’s functions.php file:
// Add Brand for Products.
add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
$entity['brand'] = 'Rank Math;
return $entity;
});
Replace the “Rank Math” text with your actual brand name then run your website through the Structured Data Testing tool once again.
For the GTIN, ISBN, MPN issue, you can fix it by adding that to your products using the custom product attribute feature in WooCommere or you can use this plugin: https://wordpress.org/plugins/product-gtin-ean-upc-isbn-for-woocommerce/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
