KDP Keywords — Amazon Keyword Research for Book Publishers

Every keyword Amazon will suggest for your topic, in one ranked list — without paying for the privilege. KDP Keywords pulls its data straight from Amazon's own search suggestions: the same phrases that appear when a shopper starts typing in the search box. It asks Amazon 131 questions about your seed word at the default depth — up to 807 if you want everything — and merges the answers into one ranked list. A typical search finishes in about a second. WHAT'S FREE • YOUR 7 KDP KEYWORD BOXES, FILLED — one click turns your results into the seven fields KDP asks for. No word repeated (Amazon merges all seven into one index, so a repeat is wasted space), your title's words skipped automatically, and your 350-character allowance packed as full as your keywords allow. • Unlimited searches. No daily cap, no trial counter, no "you have 3 uses left" • Every keyword visible — nothing blurred, nothing locked behind a signup • All four search depths, up to 807 queries per seed • Books, Kindle Store, Audible and all-departments categories • Filter, sort, long-tail-only, and automatic misspelling detection • A free sample of live competition data on every search, so you can see exactly what the paid feature does before deciding • Copy any keyword, or copy the whole list, with one click • No account. No login. No email required HOW IT RANKS RESULTS Keywords are ordered by how many different query shapes surfaced them — a phrase that turns up again and again is central to the niche, not a fluke. We also show where Amazon itself ranked the phrase in its own suggestions. We do NOT show a "search volume" number. Amazon does not publish one for these suggestions, and we would rather show you a real signal than an invented figure dressed up as data. WHAT THIS LIST IS, HONESTLY These are phrases people type into Amazon's search box in the category you pick. That is a demand signal, not proof of a book niche — popular shopping queries from other departments do sometimes drift in. Seed it like a reader ("cozy mystery", "grief journal") rather than like a product, and use competition depth to tell a real niche from noise. The extension says so on screen rather than letting you find out later. PAID UNLOCK (optional, one-time) The research above stays free forever. Paying unlocks: • COMPETITION DEPTH — see how many books already target each keyword, so you can find the phrases with demand and thin competition. This is the number that decides whether a niche is worth writing for. • CSV export, with breadth, rank and competition columns • Saved keyword lists, kept per book Competition depends on Amazon's live search results, so it can be temporarily affected if Amazon changes their pages — the free tools never do, and always keep working.

Every search runs in your own browser, straight against Amazon's public suggestion endpoint — there is no server of ours in the middle, no analytics, and no account. Your seed words cannot reach us, because there is nothing to send them to. Searches are made without cookies, so they are not tied to your Amazon account either. Full privacy policy: https://nikos6761.github.io/kdp-keywords/ The one exception is paying: checkout is handled by ExtensionPay and Stripe, who need your email address to remember that you paid. Free users are never asked for one. PERMISSIONS Two at install, and no more: • completion.amazon.com — Amazon's suggestion endpoint. This is the whole free product. • extensionpay.com — the payment provider, used only if you choose to unlock. No access to your browsing history, your tabs, or any other site. Competition depth additionally needs to read amazon.com search pages, so it is requested only if and when you use that feature — never at install. Built for KDP authors, low-content publishers and anyone doing Amazon book keyword research who is tired of being metered.
