Amazon Category Finder
The best-fit KDP categories for your book
Category choice decides which bestseller lists your book can reach. A broad category means competing with thousands of titles; a precise sub-category means a realistic path to a number one badge. Describe your book and get category suggestions to check against Amazon's current list.
How many categories can a KDP book be in?
You choose up to three categories when publishing, and Amazon may place your book in more based on its metadata. Because the store ranks bestsellers within each category, sitting in three well-chosen niches gives you three chances at a visible rank and a category badge.
Should I pick broad or narrow categories?
Narrow. A number one in a specific sub-category earns the orange bestseller flag, drives the also-boughts, and is far more reachable than mid-list obscurity in a huge parent category. The best pick is the most specific category that still genuinely describes your book.
How do I request more categories?
Amazon reduced the selectable count to three, but you can sometimes reach additional relevant categories through keyword phrases that map to them, and by making sure your description and metadata clearly signal the niche. Always verify a category still exists in the live store before relying on it.
