Customer Reviews
Customer Reviews
The Amazon Community team enables customer reviews, allowing customers to learn about other readers feedback about your books and make purchase decisions.
Below are some of the most common causes of missing reviews:
Do you believe a review violates our Community Guidelines? If so, you can notify our moderation team by clicking Report Abuse at the end of the review. The Amazon Community team will investigate, but will not respond to you.
If you need further assistance, write to community-help@amazon.com.
Amazon calculates a book or product’s star rating using a machine-learned model instead of a raw data average. The machine-learned model considers several factors including the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases. Learn more: Product Star Rating.
Customer reviews posted on detail pages for Amazon.com titles cannot be transferred to detail pages for international Amazon marketplaces such as Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.es, or Amazon.it, and vice-versa.
To share customer reviews between different book versions, the new version of your book metadata information must match the previous version of your book. Visit Link Your Books Together for more details about books linking.
If you update your book content, customers may call attention to aspects of the book that you've changed in their review. This may make content in earlier reviews irrelevant. However, we won't remove the reviews if they don't violate our Community Guidelines. Learn how to update your book and notify customers of the updates
You may provide free or discounted copies of your books to readers, as long as you do not require a review in exchange or attempt to influence the review. Offering anything other than a free or discounted copy of the book—including gift cards—will invalidate a review, and the Amazon Community team will remove it. To learn more, see Community Guidelines.
Customers value unbiased book reviews. You're welcome to encourage others to read your book and post their reviews on its detail page. For more information visit Community Guidelines.
