KDP Category Finder
Describe the book you're about to publish, or paste a competitor's Amazon link. We tell you which KDP categories to pick and how competitive each category's lists are. No sign-up needed.
How many categories can a KDP book have?
Each format (print, Kindle) gets 3 categories. A good mix is 1 broad category with many readers plus 2 niches with less competition and a lower bar to rank.
Where do the results come from?
We match Amazon's storefront category tree to KDP's category picker and crawl every category's Best Sellers and New Releases daily, so we can give you the KDP path and the list competition.
What does "pickable in KDP" mean?
KDP only lets you pick leaf categories. For a result marked "parent", click "See pickable subcategories" to get the ones you can select.
How do I choose KDP categories?
Start with categories that genuinely match your book's content and readers, then compare competition: the fewer reviews the top best sellers have and the more new releases on the list, the easier it is for a new book to break in. A book in the wrong category won't reach the right readers even if it ranks.
Can I change categories after publishing?
Yes. Edit the book's details on your KDP Bookshelf, pick new categories and submit; the change usually shows on Amazon within 72 hours and keeps your reviews and rank history.
How are Amazon store categories different from KDP categories?
The store tree is what readers browse on Amazon and has more, finer nodes; the KDP category picker lists only the selectable subset. This tool maps one to the other, so you can see which KDP path leads to a given best-seller list on Amazon.
How many free lookups do I get?
Without an account: 10 lookups and 3 AI suggestions a day. Sign up free and verify your email for more each day, plus full competition data for every category.
