Buying or swapping reviews
Paid, swapped, or friends-and-family reviews break Amazon's rules and can be removed, along with the trust they were meant to build.

Most books that don't sell have one specific bottleneck: readers never see them, see them but don't click, or click but don't buy. Use the free diagnostic below to find yours, then fix the 12 most common causes without breaking Amazon's rules.


A book usually isn't selling on Amazon because of one of three bottlenecks. Visibility: shoppers never see it, often due to weak keywords, poorly matched categories, no ads, and no outside traffic. Clicks: shoppers see it but scroll past, usually because of the cover, title, price, or few reviews. Conversion: shoppers visit but don't buy, usually because of the description, the look-inside preview, reviews, or price. Find the failing stage first; fixing the wrong one wastes time and money.

How Amazon Sales Happen
A sale only happens when a shopper gets through every stage. Your sales are limited by the weakest one.
Your book appears in search, categories, ads, or recommendations.
The thumbnail earns a click over competing books.
The product page convinces the shopper to buy.
Sales continue after launch and lead to the next book.

Causes & Fixes
| # | Reason | Stage | How to fix it |
|---|---|---|---|
| 1 | Keywords don't match how readers search | Seen | Use all 7 KDP keyword fields for real reader phrases; don't repeat title words or use banned terms like program names. Listing optimization |
| 2 | Wrong or overly broad categories | Seen | Choose up to 3 accurate, specific categories where similar books sell. |
| 3 | No traffic beyond Amazon search | Seen | Build a mailing list and author site, pitch podcasts, and promote to your network. Author website |
| 4 | No ads, or ads with poor targeting | Seen | Run Sponsored Products against keywords and comparable books, measured against break-even ACOS. Amazon Ads |
| 5 | Cover doesn't signal the genre | Clicked | Compare with bestsellers in your subcategory at thumbnail size; redesign if it looks out of place. Cover design |
| 6 | Unclear title or missing subtitle | Clicked | Add a subtitle that states the promise (nonfiction) or signals the genre (fiction). |
| 7 | Price out of line with the category | Clicked | Price close to comparable books; avoid paperback prices just under $9.99, where KDP pays 50% instead of 60%. Royalty calculator |
| 8 | Few or no reviews | Clicked / Bought | Run an advance reader program; never require reviews for free copies or use friends and family. Launch services |
| 9 | Description doesn't hook in the first lines | Bought | Lead with a short hook, then stakes or promise; use KDP-supported formatting only. |
| 10 | Look-inside preview has errors or poor formatting | Bought | Professional editing and formatting; the opening pages are your sales pitch. Book editing |
| 11 | No launch plan, so sales never built momentum | Repeated | Relaunch with reviews, a promotion window, and ads running together. |
| 12 | Only one book, no next step for readers | Repeated | Link readers to your next book or mailing list from the back matter and author page. |
AVOID THESE
Paid, swapped, or friends-and-family reviews break Amazon's rules and can be removed, along with the trust they were meant to build.
Other authors' names, "bestseller," or program names in your metadata violate KDP's rules and put your listing at risk.
Ranking #1 in an unrelated category shows your book to the wrong readers, and Amazon may change your categories anyway.
More ad spend sends more people to a page that doesn't convert. Fix the page, then scale.
A lower price can't fix a cover that doesn't get clicks, and it can cut your royalty band.
Change one major element at a time so you can tell what actually worked.
If the book is strong but the description, keywords, or categories are weak. Lowest cost, fastest test.
If the cover or editing held the book back. New packaging plus a focused promotion window.
For series and genre fiction, a second book often lifts sales of the first. Use what you learned.
