Product errors

Hello,

Thanks for your query.

Rank Math takes 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.

You can fix the brand error by making use of the following code in your theme’s functions.php file:

add_filter( 'rank_math/snippet/rich_snippet_product_entity', function( $entity ) {
    $entity['brand'] = 'Rank Math'; // You can fetch attribute value and pass it here
    return $entity;
});

In regards to the other errors, you need to ensure that the product image and SKU is set as shown below: http://i.mythemeshop.com/3MmkPe
You can also fix the “priceValidUntil” “availability” errors by setting a stock amount, sale price and sale price expiry date as shown below:

You can set the gtin value by installing the following plugin: https://wordpress.org/plugins/woo-add-gtin/
