Thanks for answering me. But regarding WooCommerce
I don’t use any plugins. The other problems I will be able to solve through the link you gave me. Thank you again.
Hello,
I assume you are using Rank Math’s pre-made schema type “Product” schema. This schema type will not automatically retrieve the product details from your post/page so you need to manually provide all property values.
Kindly refer to our KB guide to resolving some of the missing properties.
If you need our help with that, please don’t hesitate to ask. We are here to help you.
Hello,

If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
