Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
The Product Schema is only used for an actual product page. This is also included in Google’s guidelines for using the product schema:
https://developers.google.com/search/docs/data-types/product

I would suggest using the blogpost or article schema since it seems that post is a review of the product.
I hope that helps. Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
Ok so I will switch product schema to post schema, but can I use (schema by rankmath) inside the article.
What does it would show or do?
Hello,
Thank you for the follow-up.
but can I use (schema by rankmath) inside the article.
I’m assuming you are referring to the Schema by Rank Math in the block editor. If you are using any Schema type other than article Schema from the schema generator, the Schema by Rank Math block will help you insert the Schema information on the frontend as well.
By default, the Schema information is only added to the page’s source code where bots like Google can see the Schema information. The Block helps your regular visitors see that information as well.
I hope that helps. Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
