1.How they work with keywords

KDP says categories, “along with keywords you select, tell Amazon where to ‘shelve’ your book in its digital store.” Keywords are more specific, so they help when no category fits your book exactly.

2.How they affect rank

A book has a Best Sellers Rank in each of its categories, shown under Product Details on its page. A smaller category can mean a better category rank for the same sales, since the rank is relative to the other books there.

Pick categories that describe the book. A reader who lands in the wrong one won’t buy it. Before you choose, open each category’s Best Sellers list on Amazon to see the books you’d rank against.
