KDP - Kindle Direct Publishing is a platform on Amazon which allows you to publish books and sell them through Amazon websites. Authors use it to publish their e-books and paperback books. People like me use it to publish activity books. The kindle method for non-writers works in three ways: No-content books (notebooks, comics, etc) Low-content books (journals, trackers, prompt notebooks) Activity books (coloring books, crosswords, puzzles, etc) I've tried each of these in the last month, and I've had the most success with activity books. I've had 241 sales with 68 books live: The best sellers for me are mandala coloring books. My most popular mandala coloring book has sold 61 times with over $101.46 in royalties. I create my mandala coloring books in Adobe Illustrator with this add-on: You can buy the add-on here, it's only $11. I could upload and share it, but I don't want to since it's a small investment and I want to support the creator for providing such a useful tool. For research and listing, I use Bookbolt. I came across a coupon code for it on a Facebook group about KDP and decided to give it a try. The coupon was 20offsale, no idea if it's still valid. I haven't had the time to test all its features, but I'm using the KDP spy chrome extension and the auto uploader to save time. I could use the mass converter to create notebook covers in bulk (no-content books), but I'm sticking to my mandalas for now even if it takes time and effort to create them. I want to fill my account with at least 500 high quality activity books, and after that I might start uploading notebooks. People are making money selling empty notebooks only, but my approach is quality first and quantity after. Another niche that sells well on KDP are puzzles (mazes, crosswords, sudoku, word search, etc). I've uploaded a few mazes and sudoku books, haven't sold a single maze book but some sudokus: Creating the sudokus manually is quite time consuming, and I didn't like any of the free tools online.So last week I hired someone to build me a sudoku generator that would generate upload-ready PDFs. And yesterday, I came across a promotion (in a Facebook group, you guessed it) of a puzzle generator software. I spent $100 on the developer (bad luck brian), but saved some bucks with the summersale20 coupon on the Puzzle software (it's something ¯\_(ツ)_/¯ ). I plan on hiring an illustrator to create some coloring books for kids for Halloween and Christmas. Unicorn coloring books is a very hard niche to enter, but once you're in - they're selling like hot cake. The idea is to keep them low priced (with no profit at all), and build up reviews for next year. The coloring book niche is a not a sprint, but a marathon. In the long run, I want to get on this level: I consider the KDP method easy, since you have all the niches and ideas in front of you. It just requires effort and constant uploading. I plan on posting updates at least once a week, in hopes to inspire fellow BHW members to follow along my journey. Wish me luck!
