Amazon has quietly made another change that could affect how authors build reviews, particularly if you rely on international readers or third-party review services. While the update may seem like a small policy adjustment, it reflects a much larger trend: Amazon is becoming increasingly aggressive about protecting the authenticity of its review ecosystem.
At the center of the change is Kindle gifting. Authors can no longer gift Kindle books through Amazon to readers outside the United States, making it more difficult to distribute review copies internationally through Amazon’s system.
The reason appears to be Amazon’s ongoing effort to combat manipulated reviews. Many questionable review programs have historically relied on international reviewers because gifting a Kindle copy through Amazon created a “Verified Purchase” review, giving those reviews additional credibility. As Amazon’s systems have become better at identifying suspicious review patterns, it appears the company is tightening that loophole, even if it means legitimate reviewers get caught in the process as well.
Unfortunately, this creates challenges for authors who have built genuine relationships with readers and reviewers around the world. Many respected reviewers live outside the United States, and authors who have worked hard to build international audiences now have fewer convenient options for delivering advance review copies. While alternative distribution tools such as BookFunnel still exist, it’s unclear whether Amazon will continue to view reviews generated through those methods the same way over time. That uncertainty means authors should be realistic about how future review campaigns are planned.
The discussion also highlights another issue authors often overlook: not all reviews carry the same signals of authenticity. Amazon appears to pay attention to reviewer behavior as much as review content. Accounts that have reviewed only a single book, or display unusual reviewing patterns, are more likely to raise red flags than reviewers with established histories. While Amazon has never publicly disclosed exactly how these decisions are made, its continued efforts to remove suspicious reviews suggest that reviewer credibility is becoming increasingly important.
Goodreads users are also feeling the effects. Kindle Giveaways have long been limited primarily to U.S. participants, leaving international readers unable to participate. Print Giveaways, however, remain available to a much broader audience and often attract significantly more entries, making them an attractive alternative for authors willing to ship physical books.
The broader takeaway is that authors should continue focusing on legitimate, reader-first review strategies. Building an engaged advance reader team, encouraging Amazon followers, nurturing authentic reviewer relationships, and avoiding services that promise unrealistic numbers of reviews will likely become even more important as Amazon continues refining its policies. While these changes may create additional hurdles, they also reinforce a principle that has become increasingly clear across every aspect of book marketing: sustainable visibility comes from authentic reader engagement, not shortcuts.
