How to Find Best-Selling Coloring Book Ideas for Amazon KDP

About this video

Sean analyzes the coloring-book brand Mirror Luna, which he says — using a sales-estimation tool — is doing around $21,000 a month in revenue, down from a peak he puts at like $40K a month, with a Q4 rebound expected. The brand has no author profile picture or bio. Its former bestseller was overtaken by ‘Cutis Serial Killers’ (as transcribed) and its second bestseller is Cozy Crime Scenes. He estimates the top book at $154 to $214 a day and the second at $69 to $85 a day. The innovation, he argues, was being first to combine the trending cozy, bold-and-easy style with a new theme — cute, funny crime scenes / horror, with actually gory images of animals being killed — tapping an audience that also likes true crime. According to Helium 10 as he shows it, they run Amazon ads to 91 keywords, focused on hyper-relevant terms like crime scene coloring book and true crime coloring book plus big generic terms; social media is minimal, with creator videos appearing to happen organically. His general formula: style and theme are different — keep a proven style and mix in a new theme. Examples he cites include cozy Japan, cozy eras (1980s, 1990s), horror movies plus cats, silly crimes, cozy fantasy (one book doing $57 a day, another $5 a day with just seven reviews), and triple combinations like spooky Christmas or Christmas crime scenes, using ChatGPT/theme lists from Amazon to ideate. Copying the original now performs worse because buyers tire of the same images. To produce such a book, he says illustrators on Fiverr can do the whole book for around $300 to $400.

• He separates style from theme: mix a working style with an untested theme, or even three topics, to be first to market
• He says the brand runs ads to 91 keywords per Helium 10, with minimal social media — uniqueness drove organic creator pickup
• Outsourcing a full cozy coloring book via Fiverr freelancers costs around $300-$400, per his examples
