Evaluate a KDP keyword idea for relevance, search intent, specificity and an estimated competition level. Transparent heuristics only — no login, no credits.
Check a keyword
These results are estimates and are not official Amazon search-volume or competition data.
How this keyword check works
The check is deterministic and fully local. It looks at how many words the phrase has, how generic those words are, whether punctuation or repetition wastes characters, how much the phrase overlaps with the topic you entered, and which wording signals informational, commercial or reader-focused intent.
Because it has no authorised Amazon data source, it never reports search volume, sales rank or a number of competing books. Use it to sanity-check wording, then validate demand by searching the store yourself.
Official KDP help: keywords and metadataFrequently asked questions
- Is the competition score official Amazon data?
- No. The competition estimate is a transparent heuristic based on the phrase itself — its length, specificity and how generic the wording is. It is not official Amazon competition data.
- Does this tool show Amazon search volume?
- No. This tool has no access to Amazon search volume, bestseller counts or rankings, and it never invents those numbers.
- How should I choose KDP keywords?
- Favour specific phrases a reader would actually type, describe what is genuinely inside your book, avoid repeating your title, and use all seven keyword fields with different angles such as audience, format, theme and occasion.
