How do I report a customer review violation?

If you believe a review violates the Community Guidelines, click the Report link underneath the review. The Amazon Community team will investigate and take appropriate action. For privacy reasons, this team won't share the outcome of their investigation.

Why is my book review missing?

To keep customer reviews trustworthy, safe, and useful, reviews are only posted once Amazon Community team confirms they meet the Community Guidelines. These checks can take a few days.

Below are some of the most common causes of missing reviews:

• The review conflicted with Community Guidelines. This includes our rules against spam, hate speech, and reviews posted in exchange for compensation.
• The review was removed by the customer who submitted the review.
• The review was linked to an unrelated product.

If a customer contacts you about their missing review, ask them to contact Amazon Community team.

How can customers submit a review?

To submit a review, customers can find the book in Your Orders or go to the reviews section of the book page and select Write a product review. After they submit a review, Amazon Community team will check if it meets the Community Guidelines.

How are product's star ratings calculated?

Amazon calculates a product's star rating using machine-learned models instead of a simple average. To learn more visit: Understanding Customer Reviews and Ratings.

Can I share customer reviews across marketplaces?

Sharing international customer reviews is only possible across marketplaces where the same book's ASIN and format is live. For instance, if you have a paperback book available in Amazon.ca, but available only as an eBook in Amazon.com, it will not share international customer reviews.

Note that sharing reviews across marketplaces is determined by different inputs that may change over time. Because of this, your books may or may not show customer reviews across marketplaces.

Can I transfer customer reviews from a previous version of my book to a new version?

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.

Do you remove reviews about earlier versions of updated books?

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 the Community Guidelines. Learn how to update your book and notify customers of the updates.

Can I give free discounted copies of my books to readers?

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, check the Community Guidelines.
