Can I use a competitor book title as a KDP keyword?

No. Use competitor research to discover generic genre, trope, topic, audience, and reader-language phrases, not another book's unique title.

Can reverse ASIN tools find book keywords?

Yes. Reverse ASIN tools can suggest searches associated with competing books, but every result still needs relevance, competition, and compliance checks.

How many competitor books should I research?

Start with five to ten close competitors. That is usually enough to identify repeated language without allowing one unusual book to distort the keyword list.

How do I find KDP keywords from competitor books?

Find KDP keywords from competitor books by studying comparable titles, subtitles, categories, descriptions, reviews, and search visibility for generic phrases that accurately describe your own book. Use competitors to discover reader language, not to copy unique book titles, author names, or misleading metadata. Start with books that a reader could reasonably consider instead of yours. Match format, audience, genre, theme, tone, topic, price range, and publication purpose. A bestselling thriller is not a useful comparison for every mystery, and a broad cookbook is not automatically comparable with a specialist dietary guide. For a cosy bakery mystery, useful competitors would share the cosy mystery genre, an amateur sleuth, a small-town setting, and a food-related hook. Record their categories, subtitle language, recurring description phrases, review vocabulary, and the searches where they appear. List repeated generic concepts from product pages and reviews, then group them by genre, subgenre, trope, setting, character type, problem, audience, and reading experience. Search each seed phrase in Amazon autocomplete to find natural long-tail wording and related searches. A reverse ASIN tool can reveal phrases associated with competing books, but treat the output as candidates rather than approved metadata. Remove irrelevant terms and check whether each phrase honestly describes your book. Combine strong words into natural phrases instead of filling boxes with disconnected terms. Check that the exact phrase accurately describes your book, appears naturally in Amazon search behaviour, and is neither too broad nor misleading. Review the search results to confirm that books like yours appear and that the competition level fits your sales and review strength. Remove prohibited or risky metadata, including competitor author names, unique titles, unrelated claims, category names used deceptively, and promotional wording. Prioritise seven phrases that cover different reader intents rather than repeating the same root words in every box.
