Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
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.

If you don’t have any reviews yet, that is going to show up as a warning in the schema testing tool. That’s because Google will actually look for those fields.
Please acquire some reviews and ratings to get rid of the aggregateRating
and review
warnings.
You can fix the SKU and availability issue easily as well:

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.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Thanks Anas. The product details contains:
URL
Description
Product Name
None of the other fields pull through onto the category page. I have checked the products on the page which all have SKU, brand and an image defined but yet they are not pulling through. Is there another setting I should be setting to make the attributes appear? Is this a Rank Math Pro feature?
Hello,
Thank you for following up.
Since that page is a Category archive, the Schema needs to be disabled there. Please head over to Rank Math > Titles & Meta > Categories and enable the “Remove Snippet Data”:

If you’re not seeing that option, make sure your Rank Math is set to Advanced Mode in Rank Math > Dashboard:

Google recommends disabling the schema to your product category archives and the product Schema is only for the actual product and not for anything else. You can check this link for more information:

I hope that helps. Thank you, and please don’t hesitate to contact us if you need further assistance.
