A practical guide for readers who want to help authors — and authors who want more honest reviews
Amazon reviews might seem like a small thing — a few stars and a sentence or two. But for both readers and authors, they carry enormous weight. Research shows that 82% of people check reviews before buying a product on Amazon, and books are no different.
In this episode of Easy Peasy Books, Gillian Whitney — business book coach and author — walks through exactly how Amazon reviews work, what gets them declined, and the schemes you should stay well clear of.
If you've ever wondered why your review didn't go through, or how to genuinely grow your book's reviews without cutting corners, this is your guide.
The Good: Why Amazon Reviews Matter
Reviews serve two audiences at once. For readers, they're a filter — a way to figure out whether a book is worth their time and money. For authors, especially independent and self-published authors, they're social proof that can make or break discoverability.
"82% of the people will look at a review before they select a product on Amazon — and the same is true for books."
What's Actually Inside an Amazon Review
Amazon has made the review process fairly straightforward. Here's what a full review includes:
- Star rating — 1 to 5, with 5 being the highest (required)
- Headline — a short, snappy summary of your take on the book
- Review body — minimum 20 words; the sweet spot is one to two focused paragraphs
- Optional photo — ideally you holding the book
- Optional video — a short, personal video review
You can leave a review directly from the Kindle app (on any device) or by going to the book's page on amazon.com and clicking "Write a review."
What Makes a Review Actually Helpful?
Amazon itself suggests a few prompts to guide you: What did you like or dislike? Who would you recommend this book to? Why did you give it the rating you did? Those are good anchors.
Gillian's approach: step back from the relationship you might have with the author and speak directly to the reader. A real example from the episode — when reviewing Annette Richmond's book, Gillian focused on a specific, useful detail: the chapter on captioning videos. That's the kind of concrete, specific takeaway that helps a stranger decide whether to buy.
Helpful button: Under each review is a small "Helpful" button. Clicking it pushes that review higher in the rankings — like an upvote. If a review genuinely helped you, click it.
Gillian's Framework: How to Write a Review Worth Reading
After years of writing and collecting reviews, Gillian uses a simple five-step approach that keeps reviews honest, useful, and less likely to be declined:
Step 1: Choose your stars honestly
Rate the book for what it is, not who wrote it. A four-star review from someone who genuinely engaged with the content is more valuable than an unearned five.
Step 2: Write a headline that hooks
Think of it as the one-sentence version of your review. Short, specific, and ideally something a stranger would find useful — not just 'Great book!'
Step 3: Name the audience
One of the most helpful things you can do is say who the book is for. 'This is perfect for someone just starting out on LinkedIn' or 'Ideal for coaches who want to write their first book.'
Step 4: Share your single best takeaway
What idea, chapter, or moment actually changed how you think or act? One specific example beats three vague ones every time.
Step 5: Post text first, then add media
Amazon approves text reviews within a day or two. Photos and videos can take up to three weeks. Post your written review first, then go back and add a photo or video once the text is live.
Pro tip: Write your review in a Word doc or note first, and save it. If Amazon declines it, you can tweak and resubmit without starting from scratch. This alone will save you a lot of frustration.
The Bad: Why Reviews Get Declined
Getting a review declined after putting in the effort is genuinely frustrating. Here are the most common reasons it happens — and how to avoid them.
The $50 Rule
To leave a review, you must have spent at least $50 on Amazon using a credit or debit card within the past year. Gift cards don't count. This catches a lot of people off guard.
Gillian ran into this herself — she had around $300 in Amazon gift cards from clients and family, used them as her book fund, and couldn't leave reviews for two years until the gift cards ran out. She's making up for lost time now.
Focusing on the Author Instead of the Book
Amazon will decline reviews that read more like a character reference than a book review. Even if you know the author personally and think the world of them, that's not what a potential buyer needs to hear. Speak to the book's value for the reader — not to your feelings about the person who wrote it.
Family, Household Members, and Amazon-Connected Friends
You cannot review a book written by someone in your household — Amazon tracks IP addresses. And 'friends' in Amazon's view includes people you've sent gifts to or received gifts from through the platform. Gillian won't even ask her sister to review her book, even though they live in different cities and have different last names. The connection is there in the purchase history, and it's not worth the risk.
Colleagues and professional connections — like LinkedIn contacts — are generally fine, as long as the relationship is genuinely professional.
Reviews That Are Too Promotional or Cross Other Lines
Harassment, libel, or content that attacks the author rather than evaluating the book will also be removed. Keep it constructive and on-topic.
The Ugly: Fake Reviews and What to Avoid
There's a whole industry built around manufacturing Amazon reviews. Gillian has seen authors approached by companies offering to deliver a batch of reviews for a fee. The answer should always be no.
Review Pods
Review pods are groups of authors who agree to review each other's books — essentially trading reviews. Just like LinkedIn engagement pods, they produce inflated, inauthentic signals. Gillian is clear: stay out of them.
Incentivized Reviews
Offering anything in exchange for a review — a coaching session, a prize draw entry, a free copy with an expectation attached — violates Amazon's guidelines. Even if you gave someone a complimentary copy, you cannot pressure or expect them to review it.
"Even if somebody gives you a copy of a book for free, you do not have to post a review. Amazon does not want people giving you an incentive to post a review."
What Amazon Is Doing About It
Amazon now runs every review through AI checks before it goes live — analyzing reviewer history, timing, and the relationship between the reviewer and the author. Videos are transcribed. Photos are scanned. Suspicious reviews are escalated to human moderators.
Amazon has also taken legal action — including against a Facebook group running a coordinated fake review operation. The consequences are real: reviews removed, accounts banned, and in some cases, litigation.
For Authors: How to Grow Honest Reviews
Only about 1 to 2% of readers leave reviews — yet 82% of buyers rely on them. That gap is the challenge every author faces. Here's what actually works.
What Works
- Ask your beta readers: They've already read the book. If they found value in it, invite them to share that on Amazon once it's published.
- Add a CTA at the back of your book: A simple, low-pressure note — 'If this book helped you, I'd be grateful if you'd leave a review on Amazon' — goes a long way. Gillian includes this in all her books.
- Mention it to your audience: Not a plea for five stars, just a reminder that reviews help other readers discover the book.
- Give beta readers and launch team members full freedom: Encourage honesty, not positivity. A four-star review that explains what the book is great for is more trustworthy than ten generic five-stars.
What Doesn't Work (and Can Hurt You)
- Asking family members or anyone in your household
- Offering anything in exchange for a review
- Joining review pods or exchange groups
- Paying for review packages from third-party services
"I'd rather have a few reviews that I know my book actually mattered to some people than to have the vanity metrics of having all these fake reviews."
One Last Thing
If you've read a business book by an independent author recently and found genuine value in it, go leave them a review. The big-name bestsellers don't need it as much as the self-published author who poured their expertise into a book and is quietly hoping more people will find it.
It takes five minutes. It pays it forward. And as Gillian puts it — just be kind.
