Issue with Book Schema Markup

Hello @amnwtritaly,
 
Thank you for contacting us and bringing your concern to our attention.
 
We can see the Book Schema is properly included on your homepage. Please check this screenshot for your reference: https://i.rankmath.com/i/xyG8v4
 
However, please note that the Book Schema is not eligible for rich results with Google’s Rich Results test tool. You can see the supported types here: https://support.google.com/webmasters/answer/7445569?hl=en#zippy=%2Csupported-types 
 
You’ll have to check the Schema at https://validator.schema.org/ 
 
Hope that helps and please don’t hesitate to let us know if you have any other questions.
