Why people aren't finding your bookPriority
Your title and subtitle target the same search phrase in three different ways. You are not using the keywords readers use when looking for books in this genre.
Why people aren't buying your bookPriority
Your description retells the plot in order. Thriller readers buy the hook and the stakes, and yours don't appear until the third paragraph.
Where your words lose them
Your description opens with a review quote. On mobile, shoppers hit "Read more" before they know what the book is about.

Why a KDP listing can hold back an otherwise good book
Low sales are not always a demand problem. Sometimes the listing makes it harder for the right shopper to understand the book, see its relevance or decide to buy. The free audit looks at the copy a shopper sees first: title, subtitle and description.
What the free audit can and cannot tell you
It can identify visible-copy weaknesses. That includes vague positioning, unclear benefits, weak hooks and wording that makes the book harder to understand quickly.
It cannot inspect the seven KDP keyword fields. Those hidden fields can contain duplication, wasted space, formatting problems or language that adds little new information.
It does not run the complete Full KDP Fix. Full KDP Fix adds the deeper listing checks, live market and competitor research, keyword planning, category decisions and the finished changes to make next.
Amazon uses many signals. Rank Fuel does not pretend to reverse-engineer a private ranking formula. It focuses on the listing elements a publisher can inspect, improve and verify.
Frequently asked questions
What does the free audit check? +
It analyses the title, subtitle and description you provide and returns a partial score plus specific visible-copy findings. It does not inspect your seven KDP keyword fields or run every check in the full Listing Audit.
What does Full KDP Fix add? +
It takes the diagnosis through to the solution: deeper listing checks, live competitor and market research, keyword planning, all seven KDP keyword fields, category decisions, an improved listing and a prioritised action plan for the book.
Why is the free score capped below 100? +
Because it is deliberately a partial score. A high result for the visible copy does not prove that the hidden keyword fields or deeper conversion checks will also pass.
Do I need to enter my email? +
No. Email is optional and your audit appears on this page either way. If you enter an email, we send your partial result and the next checks to run.
Do I need a subscription for Full KDP Fix? +
No. Full KDP Fix is a one-off purchase for one book. You pay securely in Stripe first. If you do not already have a Rank Fuel account, we send a secure activation link after payment so you can open the Full KDP Fix you have already bought. There is no subscription and no second purchase step.
