Missing field hasMerchantReturnPolicy

Hello,

Thank you for reaching out about the missing field "hasMerchantReturnPolicy" warning in your WooCommerce store’s structured data. This warning typically appears when certain fields are not included in the product schema.

To address this issue and enhance your product listings, you can consider adding the "hasMerchantReturnPolicy" field to your product schema. Unfortunately, as of now, Rank Math does not provide a direct option to add this specific field through its settings.

However, you can manually add custom schema properties using filters and hooks provided by Rank Math. If you are comfortable with coding, you can utilize these filters to include additional schema properties like "hasMerchantReturnPolicy."

If you are unsure about implementing custom schema changes or concerned about potential impacts on rich snippets visibility, we recommend consulting with a developer or SEO expert who can assist you in customizing the schema without negatively affecting your search engine results.

For more detailed guidance on customizing schema properties in Rank Math, you can refer to the official Rank Math documentation or reach out to our dedicated support team by clicking here.

Warm regards.

Hello,

Thank you for your query and we are so sorry about the trouble this must have caused.

Since 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;
});
