Enter a book topic or keyword idea and get Amazon search variations scored for buyer intent, format fit, specificity, audience clarity, and standout potential. Then check live Amazon data only on the keywords that actually look worth pursuing.
Formerly Niche Navigator. Now renamed Keyword Quality Analyzer because the job is clearer: separate promising KDP keywords from expensive distractions.

Not every Amazon keyword deserves live market analysis. Some phrases sound promising but have weak buying intent. Others are too vague, too broad, or missing a clear book format. Some have no obvious audience, which makes them hard to position around.
The Keyword Quality Analyzer gives you a free first-pass quality read before you spend credits on live data.
Use it to decide which keywords are worth checking, which are worth saving, and which should be skipped before they waste your research time.
Each keyword gets a 0–100 quality score based on the phrase itself, not on hidden assumptions about the market.
This tells you whether the keyword has the shape of a good KDP opportunity before you spend credits checking it.
For selected keywords, run a live check to see estimated searches, competing books, average price, average reviews, pages, earnings, and competition score.
That turns a promising phrase into a data-backed decision.
Select one keyword or a group of keywords and send them straight into the Listing Generator.
The tool becomes the bridge between research and a real KDP listing, not just another spreadsheet of ideas.
The quality score is free and instant. It helps you filter keyword ideas before pulling live market data.
Does this phrase sound like something a buyer would type when looking for a book?
Does it match a proven KDP format, such as workbook, word search, planner, guide, journal, or activity book?
Is the keyword specific enough to avoid being too broad, vague, or impossible to position around?
Is the reader, buyer, age group, or use case clear enough to build a listing around?
Could a new book stand out here, or is the phrase too generic and crowded to position clearly?
The Keyword Quality Analyzer is designed to stop you building around the wrong keyword.
Start with a broad idea such as dog puzzles, cozy mystery, gratitude journal for teens, or any keyword you are considering.
Sort the ideas by quality and look at buyer intent, format fit, specificity, audience clarity, and standout potential.
Use credits only on the phrases that pass the pre-check. Then compare searches, competitors, pricing, reviews, pages, earnings, and competition score.
Save useful keywords to your library, copy them for later, or carry the strongest terms into the Listing Generator to build the next step.
A strong quality score means the keyword has useful KDP shape: clear buyer intent, format fit, audience clarity, and positioning potential.
That is the point where live data becomes worth checking.
A middle score may mean the idea has promise but needs refinement. It may be too broad, missing a buyer group, or not strongly tied to a book format.
Use the suggested phrase to sharpen the angle before checking live data.
Weak keywords often sound like topics, not buyer searches. They may be vague, generic, or hard to turn into a book listing.
The pre-check helps you avoid spending credits on terms unlikely to become useful KDP opportunities.
After live checking, the competition score runs from 0 to 100. Lower scores suggest an easier route into the market, while higher scores indicate a more entrenched niche.
Enter a book topic or keyword idea. The tool generates related Amazon search phrases and scores their quality for KDP potential.
Use the free quality scores to decide which ideas deserve live market checks and which should be skipped.
When a keyword has both strong quality and realistic live data, send it to the Listing Generator and build your listing around proven demand.
The Keyword Quality Analyzer helps you decide which ideas are worth testing before you write, publish, or build a listing.
Once you find a promising keyword, use the Keyword Competition Checker for deeper page-one analysis, Book Keyword Spy to reverse-engineer competing books, and the Listing Generator or Listing Optimizer to turn the research into copy.
Explore the full KDP toolkit →The quality score is a strategic pre-check of the keyword phrase itself. It does not claim to know the market and does not use live Amazon competition data.
Live checks add the market layer: estimated search volume, number of competing books, pricing, review strength, pages, earnings potential, and competition score.
Search volume and earnings are estimates, not guarantees. Use them for comparison, prioritisation, and smarter publishing decisions.
Instead of checking every idea blindly, start with quality, then spend credits only where the keyword deserves a closer look.
Yes. The tool was previously called Niche Navigator. It has been renamed Keyword Quality Analyzer to make the purpose clearer: it scores keyword quality before you spend credits on live market data.
It starts with a book topic or keyword idea, generates Amazon keyword variations, scores each phrase for strategic quality, and lets you check live Amazon data on the most promising terms.
The quality score measures buyer intent, format fit, specificity, audience clarity, and differentiation. It is a pre-data judgement of the phrase itself.
No. The quality score is free and does not use live market data. It helps you decide which keywords are worth checking with live data.
A live check can show estimated searches, competing books, average price, average reviews, average pages, estimated monthly earnings, competition score, and examples of top competing books.
Yes. Keyword ideas and quality scores are free. Live market checks use credits because they pull and enrich Amazon market data.
The competition score runs from 0 to 100, where lower is easier to enter. It combines competition and market signals to help you judge whether a keyword is realistic.
LOW means the estimated monthly search volume is very small or not meaningful enough to display as a normal number. Low-volume keywords can still be useful if they are highly specific and easy to compete for.
Yes. You can select useful keywords and save them to your keyword library, copy them, or carry them into the next step of your KDP workflow.
Use the selected keyword to build a listing with the Listing Generator, or use the keyword as part of a wider research workflow with the Keyword Competition Checker, Book Keyword Spy, and Listing Optimizer.
Start with a free quality read, then check live Amazon data only on the KDP keywords that deserve a closer look.
