Most KDP niche research looks at the wrong store

Google keyword tools tell you what people search on Google. Amazon buyers search differently, and a niche is only worth entering if two things are true on Amazon itself: people search for it, and the books ranking for it can be beaten.

Book Goldmine goes to the source. For your niche it pulls real Amazon search volumes for related book searches, reads the first page of Amazon results (price, rating, reviews), then opens the top books to get their Best Sellers Rank, estimated monthly sales and publication date.

Each keyword gets a 0–100 score: demand and proven sales against how entrenched the top books are, how many have fewer than 100 reviews, and how old they are. The editor turns the numbers into a plain verdict and, for good niches, a book idea that targets the gap.

Frequently Asked Questions

Where does the data come from?+

Amazon search volumes, search results and product pages are collected through DataForSEO, a market data provider. Sales are estimates from each book’s Best Sellers Rank, using public BSR-to-sales benchmarks.

How is the score calculated?+

Demand (Amazon searches) counts for 30%, proven sales of the top 3 books 25%, how established the top 10 are (their median reviews) 25%, the share of top-10 books under 100 reviews 10%, and the age of the top books 10%.

Why do I only see book keywords?+

Amazon’s related searches cover the whole store. "Keto snacks" is a grocery search, not a book opportunity, so only searches that are clearly about books on your subject are kept.

How many searches are included?+

Each new analysis uses one Trend Goldmine search: 10 a month on Basic, 30 on Standard and 100 on Pro. A niche someone researched in the last 14 days is free and instant.
