Choosing the right niche is the biggest decision a self-published author makes. It sets your reader demand, the books you compete against, and how hard it will be to rank on Amazon — before you write a word.
Every niche below is analysed against current Amazon bestsellers and keyword demand. BookTrendr combines those signals into one opportunity score, so you can spot Kindle niches with proven demand and room for a new book.
Together these give you a first read on the market before you invest time and money. For deeper data and competitor research, analyse the niche in BookTrendr.

Don't judge a niche by one number. Use the opportunity score as a starting point — scores here run 29 to 75, with 25 niches at 65 or above — then review the bestsellers, keywords, covers, reviews, and sub-niches before you decide.
