To add the missing fields “hasMerchantReturnPolicy” and “shippingDetails” to the schema for WooCommerce products, you can follow these steps:
1. Access your WooCommerce product settings or open the relevant product page for editing.
2. Locate the section where you can enter the product’s schema markup. This can vary depending on the theme or plugins you are using. If you have a dedicated schema plugin like “Schema Pro” or “Yoast SEO,” you can use their respective interfaces for adding schema markup. Otherwise, you may need to modify the template files directly.
Our suggestion is to use the Yoast SEO plugin, it’s fully tested with our theme.
