What the diagnosis shows
A made-up sample listing, run through the same rules as the tool.
Sample listing
- Title
- 80s Word Search
- Subtitle
- Word Search Puzzles For Adults, Seniors, Large Print, Gift
- Description
- A book full of word searches about the 80s for you to have fun.
- Keywords
- paperback · word search · 80s word search · bestseller
Diagnosis · score 28/100
Fix · 3 of the 7 fields are empty.
Each empty field is a search the book cannot show up in.
Fix · "bestseller" claims quality or an offer ("bestseller").
KDP advises against this in metadata, and buyers do not type it.
Improve · The subtitle repeats words from the title: word, search.
Repeating does not raise your chance of showing up. Use the space for a new search.
Improve · The description is short (63 characters of text).
Use the space: the reader's problem, what the book delivers and why to trust it.
Improve · Nothing in bold.
Bold on the promise and the benefits makes the description scannable on a phone.
Improve · No benefits list.
Three to five short bullets with what the buyer gets.
And 4 more findings.

Frequently asked questions
What can I change on a book that is already published on KDP?+
Under "Edit details": the description, the 7 keywords, the categories, the price and the interior and cover files. Title and subtitle of a print book can only change in the first 72 hours; after that, only with a new edition. A+ content lives under the Marketing tab and the bio in Author Central.
Does the diagnosis use AI or cost anything?+
No. It runs on rules: KDP limits and good practices from sellers in this niche. Each finding says which of the two it comes from. No sign-up and no payment.
Is the score the one Amazon gives my book?+
No. Amazon publishes no score. The score is a work order: it tells you where to start, not how much the book will sell.
Where do I find my book's keywords and categories?+
They do not appear on the public Amazon page. They are in your KDP account, under Bookshelf, "Edit details", in the book content step.
Does this guarantee more sales?+
No. Fixing the listing removes what gets in the way, but sales depend on the cover, price, reviews and who reaches the book. Change one item at a time and wait one to two weeks to see what worked.
