Rank, sales, revenue
Best Sellers Rank with every sub-category rank, estimated sales per day and per month with a low–high range, and estimated monthly revenue at the current price.
KDP royalty per sale
Paperback royalty from KDP's published formula, plus reviews, rating, page count, publication date and publisher. Independently published books are flagged.
Niche score, 0–100
Demand against competition for the top 20 organic results, with average price and reviews. Sponsored results are kept separate.
Analyze the top results
A chip on each result. Click Look up or Analyze top N to fetch BSR and estimated sales, one page at a time at a polite pace.
Honest estimates
Every sales figure is marked EST and comes from a published BSR-to-sales model for Books and Clothing. Uncalibrated categories show the real BSR and no made-up number.
