Enter any Amazon book keyword and see the books currently competing for it on page one: review counts, prices, Best Seller Rank, estimated sales, and a Potential score that shows whether a new book can realistically break in.
Use it to choose the keywords worth building a listing around, and skip the ones already locked up.
You choose the terms that feel right. You write the book. You fill in the seven KDP keyword boxes. Then, months later, you realise page one was already dominated by books with thousands of reviews, strong sales ranks, and years of momentum.
By then, the work is done and the listing is live.
The Keyword Competition Checker lets you check the market first. In seconds, you can see whether a keyword is realistic, crowded, or not worth chasing before you build your title, subtitle, description, ads, or book idea around it.
See the books currently ranking on page one of Amazon for your keyword, with Best Seller Rank pulled from product pages and key competition signals shown in one report.
Review counts, pricing, Best Seller Rank, and estimated sales are distilled into a clear Low, Medium, High, or Very High competition rating, so you can understand the market at a glance.
Demand, competition, and sales activity are combined into one opportunity score that answers the question that matters most: can a new book realistically break into this keyword?
Review count is one of the clearest competition signals. If the books on page one have low review counts, a new book may have a realistic route in. If they have thousands of reviews, the keyword may be much harder to break into.
As a guide:
Under 100 average reviews suggests a more open keyword.
Over 500 average reviews suggests a tougher market.
Over 2,000 average reviews suggests an entrenched niche.
The Low, Medium, High, or Very High competition rating turns the page-one data into an easy read, so you can quickly compare keywords without analysing every book manually.
A strong Potential score usually means the keyword has demand, but the competition has not completely locked it down. A low score is a warning to look for a better keyword before you commit time, credits, ad spend, or an entire book idea.
Type the Amazon keyword you are thinking of targeting and choose your marketplace: US or UK.
The checker pulls the current page-one results and loads Best Seller Rank and sales data for the top results automatically. You can unlock additional rows with credits when you want to go deeper.
Read the competition rating, Potential score, search volume, reviews, prices, and estimated sales. Then decide whether to build your listing around that keyword, test it in ads, or move on to an easier opportunity.
The Keyword Competition Checker tells you whether a keyword is winnable.
Book Keyword Spy shows you every keyword a specific book already ranks for. Keyword Gap Finder shows you where competitors rank and you do not.
Together, they help you find the keywords worth targeting, understand the books already winning them, and turn that research into a stronger KDP listing with the Listing Generator or Listing Optimizer.
Explore the full KDP toolkit →The Keyword Competition Checker uses current Amazon search results, Best Seller Rank pulled from product pages, and Amazon keyword search volume data to help you assess competition.
Estimated sales are calculated from Best Seller Rank using a sales estimation model. The competition rating and Potential score combine demand, competition, reviews, pricing, and sales signals into a practical opportunity read.
These figures are designed for comparison and planning. They help you judge whether one keyword is more competitive than another, and whether the market looks realistic for your book.
They are not guarantees of sales, rankings, visibility, or future performance.
Instead of guessing, check the page-one competition before you target the keyword.
You enter an Amazon keyword and the tool shows the books currently competing for that keyword on page one. It reports review counts, pricing, Best Seller Rank, estimated sales, search volume, and a Potential score showing how realistic the keyword may be for a new book.
Enter a keyword. This tool is designed to check the competition behind a search term you are thinking of targeting.
To see every keyword a specific book already ranks for, use Book Keyword Spy instead.
The tool focuses on the books competing for meaningful visibility. Page one is where most buyer attention goes, so the books ranking there are the ones you need to understand before deciding whether a keyword is worth targeting.
Average review count is one of the clearest signals. A keyword where the top books have low review counts is usually easier to enter than one where page one is dominated by titles with hundreds or thousands of reviews.
Best Seller Rank, estimated sales, pricing, title relevance, and search volume also matter.
The Potential score is an opportunity score out of 100. It combines demand, competition level, sales activity, and other keyword signals to help you judge whether a keyword looks worth targeting.
A score of 70 or above usually suggests a stronger opportunity. A low score is a cue to investigate carefully or look for a better keyword.
Estimated sales are derived from Best Seller Rank using a sales estimation model. They are directional estimates, not exact figures. Use them to compare competitors and judge relative market strength.
The top results are enriched automatically. Additional rows can be unlocked with credits if you want to go deeper. Repeat checks within an hour are served from cache, so you do not pay again for the same search during that period.
