Start with a category guide
Each guide covers the market, production specs, how to choose between niches, the mistakes that get books returned, and a full breakdown of every niche in that category.
Journals
Guided journals are the highest-margin, lowest-production-cost category on KDP — and the one where a specific reader beats a beautiful cover every time.
Planners
Planners carry the highest page counts in low-content publishing, which makes trim size and print cost the difference between a profitable planner and a break-even one.
Puzzle Books
Every niche in this category reads Low or Low-Medium competition, and the reason is that puzzle books are judged on generation quality, which most publishers get wrong.
Coloring Books
Coloring books live or die on line quality and page setup, and the winning niches are the ones with a specific subject a specific person already loves.
Children's Books
Every niche here reads Medium or Low-Medium competition and difficulty 3, because picture books demand illustration consistency that most self-published titles never achieve.
Cookbooks
Every cookbook niche here reads Medium or Low-Medium — competition is real, and what wins is recipes that demonstrably work plus a device or dietary constraint the buyer already owns.
Workbooks
Workbooks sell when the buyer can name the skill they want at the end — and they get returned when the exercises do not build on each other.
Logbooks & Keepsakes
Average difficulty across this category is 1.1 — the lowest on the platform — because a logbook is a well-designed table repeated correctly.
Nonfiction
Nonfiction carries the second-highest average difficulty on this page at 3.2, because a how-to book has to actually work — and readers say so publicly when it does not.
Fiction & Memoir
Highest average difficulty on this page at 3.8 — fiction readers buy by series and by convention, and breaking convention reads as incompetence rather than originality.
Business Books
Not one business niche here reads Low competition, and the reason is that everybody who has ever made money online has already written the book about it.
