Few things frustrate authors more than seeing a new review appear, then disappear. It can feel personal, but Amazon review removal is usually about trust signals, not the quality of the book.

A review can vanish because Amazon's systems decide it may not meet review guidelines or may not look independent enough.

Common Reasons Reviews Disappear

The reviewer may have a close connection to the author. The review may look coordinated with other reviews. The account may have unusual activity. The text may include language that sounds promotional, copied, or unrelated to the reading experience.

Reviews can also be delayed, filtered, or moved during moderation. Sometimes a rating appears without text, or a text review takes longer to show.

What Authors Should Not Do

Do not ask the same reader to repost the exact same review again and again. Do not tell a group of readers to post on the same day with similar wording. Do not contact reviewers with instructions about how to avoid filters.

Those actions can make the pattern look even less natural.

What To Do Instead

Keep asking for honest feedback in a neutral way. Build a wider pool of real readers. Make review requests part of your launch process, but do not obsess over any single removed review.

One disappeared review is annoying. A review strategy that looks manipulated is much worse.
