Readers are posting their review on Goodreads, but not on Amazon. Why?
A common reason for this is that your book's review destination is set to Amazon OR Goodreads. This means that readers get the option of posting their review on either platform. Therefore, your book will attract readers who can only post on Goodreads and not on Amazon.
If you want to specifically optimize for Amazon reviews, we recommend updating your review destination to say you want reviews on Amazon. Then, moving forward we will only show your book to readers whom we believe can post reviews on Amazon. This will be a smaller pool of readers (since readers who can only post on Goodreads will not see your book) but your chances of getting an Amazon review will increase. It is a trade off.
You can update your review destination by going to your book page and clicking the Manage button. Or you can contact us and we will update it for you.
