Amazon KDP Book Niche Analyzer: Self Publishing Niche Research

Amazon KDP Book Niche Analyzer: Self Publishing Niche Research

Check a Kindle niche against the books already competing in it. For each keyword you get every book's real Best Sellers Rank, price, rating count, age and category ranks, plus a transparent opportunity score that stays hidden until the evidence is strong enough to trust.

Start a 7-day free trial, paste your niche ideas and read the competition before you write, design or publish a single page. No card is needed for the trial.

📊 What you get

• Real sales-rank evidence. Each book carries its visible Kindle Store Best Sellers Rank and its category ranks, taken from the public book page.
• Scores that explain themselves. The opportunity score shows its demand, review-ease and competition-ease parts, and the exact formula sits in every niche summary. With fewer than five books, three visible ranks or three rating counts, no score is shown.
• Estimated sales, labelled as estimates. Monthly sales, revenue and royalty are worked out from each book's rank and price. Every estimate carries the coefficients behind it.
• A verdict row per niche. Switch it on and each keyword gets one extra row with the score, verdict, confidence, medians and the two-to-three word phrases that competing titles repeat.
• Keyword suggestions. Amazon's own suggestions come back for every keyword, and you can choose to analyze them as extra niches.
• Niche monitoring. Run the same input on a schedule and later runs report what changed since the saved baseline.
• Your format. Download Excel, CSV or JSON, or pull the data into your own tools through the API.

👥 Who it is for

• KDP self-publishers: "I want to see who ranks for this idea and how many ratings they have before I spend a month writing."
• Low-content publishers: "I compare a dozen journal and planner phrases in one run and keep the ones with weak competition."
• Coaches and course creators: "I check whether the topic of my next book already has strong, established sellers."
• Book-market researchers: "I need a repeatable file of ranks, prices and publication ages, not a pile of browser tabs."

🚀 How it works

1. Add your niche ideas. Enter Kindle keywords, paste Amazon search links, or paste the book pages of competitors you already know.
2. Set your research depth. Choose how many books to inspect per keyword and whether to add a verdict row per niche.
3. Run it and compare. Read the ranked book evidence and the niche verdicts, then schedule repeat checks on niches worth watching.

💡 Good to know

• Only public Amazon pages are read.
• Organic position is the book's place in the collected Kindle search results. It is not an Amazon bestseller rank.
• Amazon sometimes shows a checkpoint page instead of a book. Those books are skipped and counted in the run message, so a run can return fewer books than you asked for.
• The Actor is independent and not affiliated with Amazon.
