What It Is
Before writing any book, check the Amazon Best Sellers Rank (BSR) of similar, already-published books in that topic. A BSR under roughly 80,000 signals there's real, ongoing demand for that kind of book, worth knowing before you invest the time to write one.
The Pitch
This isn't a business on its own, it's a simple, free way to de-risk any print-on-demand book idea, coloring books included, before spending time on it.
Who It’s Best For
Anyone considering the Amazon KDP coloring book idea, or any similar print-on-demand book concept, who wants a cheap gut-check before committing time.
The Truth (as we see it)
The presenter also promotes a paid AI writing tool alongside this technique, but the validation method itself works fine using just a free Chrome extension and Amazon's own listings.
