Describe your book and get Amazon backend keywords and browse categories to help the right readers find it — the part of self-publishing most authors get wrong.
Amazon doesn’t just sell books — it’s a search engine for them. When a reader types “cozy small-town mystery” or “enemies to lovers fae romance”, Amazon matches that against your title, subtitle, description, categories, and your seven backend keyword phrases. Those seven slots are the lever most authors leave unpulled.
The trick is to think like a buyer, not a writer. You know your book’s themes; readers know the phrases they search. Fill the gap with reader-language phrases you haven’t already used in your title, and pick the most specific categories you honestly qualify for — that’s where new books earn their first bestseller badge.
The tool
Seven slots, reader-language phrases, and the categories that actually rank.
KDP gives you 7 keyword slots when you publish. Each slot can hold a short phrase (up to 50 characters), so you are really getting seven chances to match how readers search. This tool returns exactly seven distinct phrases you can paste straight into those slots.
Seven slots. Seven phrases. Paste them in.
