Google Search Console Issue

Hello,

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

Could you please share some affected URLs with us so that we can check the issue further for you?

Regarding the hasMerchantReturnPolicy error, Google has recently started reporting warnings for these fields, this feature is still not available in the plugin, the only possible way would be to edit the following filter with the appropriate data for these properties so it gets included in the Product Schema as well: https://rankmath.com/kb/filters-hooks-api-developer/#change-post-schema-data

We have created an example filter that would help add this data and it assumes that the refund policy is only applicable to the USA and that it has a 30-day refund period.

The shipping rate section also assumes a flat fee of 5$ to ship within the United States.

This would need to be changed according to the website specifications but it should be a good starting point:

add_filter( "rank_math/snippet/rich_snippet_product_entity", function( $entity ) {
    // Return policy
    $entity['offers']['hasMerchantReturnPolicy']['@type'] = 'MerchantReturnPolicy';
    $entity['offers']['hasMerchantReturnPolicy']['applicableCountry'] = 'US';
    $entity['offers']['hasMerchantReturnPolicy']['returnPolicyCategory'] = 'https://schema.org/MerchantReturnFiniteReturnWindow';
    $entity['offers']['hasMerchantReturnPolicy']['merchantReturnDays'] = 30;
    $entity['offers']['hasMerchantReturnPolicy']['returnMethod'] = 'https://schema.org/ReturnByMail';
    $entity['offers']['hasMerchantReturnPolicy']['returnFees'] = 'https://schema.org/FreeReturn';

    // Shipping details
    $entity['offers']['shippingDetails']['@type'] = 'OfferShippingDetails';
    $entity['offers']['shippingDetails']['shippingRate']['@type'] = 'MonetaryAmount';
    $entity['offers']['shippingDetails']['shippingRate']['value'] = 5;
    $entity['offers']['shippingDetails']['shippingRate']['currency'] = 'USD';
    $entity['offers']['shippingDetails']['shippingDestination']['@type'] = 'DefinedRegion';
    $entity['offers']['shippingDetails']['shippingDestination']['addressCountry'] = 'US';

    return $entity;
});

Here is how to add a filter to your site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

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

Thank you.
