12 marketplace category trees
Choose the Amazon marketplace you plan to publish in. Category paths and competition can differ between stores and formats.
Kindle, paperback, and BISAC
Compare both book formats. Available BISAC codes provide the publishing subject classifications associated with a match.
Should I include my subtitle?
Yes, when you have one. A subtitle often explains the subject, audience, or benefit more clearly than the main title alone.
Will every search return 20 categories?
No. Twenty is the maximum per format. A more specific book may have fewer relevant matches.
Do filters apply only to the page I am viewing?
No. Sorting and competition filters apply across the complete set of returned matches. Results are then shown ten at a time.
Does a low-competition category guarantee a bestseller?
No. Choose a category that accurately describes your book. Competition and ranking targets are research signals, not promises of rank or sales.
