Your competitors are not just “ranking better.” They are being found through specific Amazon searches your listing may be missing.
Compare your ASIN with a competitor, uncover the keywords they are winning, and send the best gaps straight into your next listing optimization.
If a competing book is showing up where yours is not, that is not just frustrating. It is useful.
It means Amazon has already connected that search with a book like yours. Keyword Gap Finder shows you those missed searches, so your next optimization is based on actual competitor visibility, not guesswork.
You are not trying to copy the competitor. You are finding the search territory your book should be competing for.
See the keywords where a competing book appears and yours does not.
These are the gaps most authors never see when they are only looking at their own listing.
A long keyword list is not a strategy. Gap data helps you focus on terms that are already working in your market.
You can prioritize the gaps with relevance, demand, and clear ranking potential.
Select the missed keywords that matter and send them to the Listing Optimizer.
Your competitor research becomes a concrete target list for improving your description and backend keyword boxes.
You know another book keeps appearing in your niche, but you do not know why.
You try adding a few keywords, rewriting a paragraph, or changing ads, but it is hard to tell whether you are targeting the right search terms.
The problem: you are optimizing from the outside.
You can see the searches where the competitor has visibility and your book is absent, weaker, or fighting in the same territory.
You know which gaps are worth saving, which strengths to protect, and which terms to send into the Listing Optimizer.
The outcome: your next listing update has a reason behind it.
Keyword Gap Finder is built to help you make a decision, not admire a spreadsheet.
Enter your ASIN and a competing Amazon.com ASIN to see where the two books overlap and diverge in search.
Look for the searches where the competitor ranks strongly and your book is absent or weaker.
Not every competitor keyword is worth chasing. Select the gaps that match your audience, format, and book promise.
Use the selected gaps as target keywords for your description and seven KDP keyword boxes.
After the listing changes go live, monitor those keywords in the Rank Tracker so you can see movement instead of guessing.
Use competitor gaps as target keywords when they genuinely fit your book.
These are the terms your listing may need to signal more clearly in the description or backend boxes.
Your strengths show where your book is already doing something right.
Use those terms as protected keywords when making listing changes so you do not damage existing visibility.
When both books rank for the same term, you are already in the conversation.
Those searches may be easier to improve than keywords where your book has no visibility at all.
You want to know which searches similar books are being found through before changing your listing again.
You have spotted a book that appears around your niche and want to know which keywords are helping it appear.
You need target keywords for the Listing Optimizer and want them based on competitor evidence, not a brainstorm.
Competitor Discovery helps you find the books Amazon places around yours. Keyword Gap Finder shows what those books are ranking for. Listing Optimizer turns the best gaps into improved listing copy.
That gives you a simple research path: find the competitor, uncover the missed searches, optimize your listing, then track the result.
Explore the full KDP toolkit →Do not target every gap just because it appears in the report.
Choose the gaps that genuinely match your book, audience, format, and promise. A relevant gap can help sharpen your listing. An irrelevant gap can make your copy weaker.
The tool shows you where to look. Your strategy decides what to act on.
Instead of staring at a competitor and wondering what they know, uncover the keywords behind their visibility.
It compares your Amazon.com ASIN with a competitor ASIN and shows where the competitor has keyword visibility that your book may be missing.
A keyword gap is a search term where a competing book ranks and your book is absent, weaker, or not in the same position. These terms can become target keywords for optimization.
Because not every competitor keyword fits your book. The goal is to find useful opportunities, then choose the terms that match your audience, content, and positioning.
My Strengths are searches where your book ranks strongly and the competitor does not. These are useful because they show what your listing may already be doing well.
Both Ranking shows search terms where both books appear. These are useful because your book already has some visibility, so improvement may be more realistic.
