How to Choose Amazon KDP Keywords
Amazon KDP currently gives authors up to seven keyword fields. The difficult part is not filling seven boxes; it is choosing phrases that match the book closely enough to help the right reader recognise it. This guide shows a practical way to build those entries without keyword stuffing or speculative guarantees.
Start with reader intent, not a keyword tool
A reader rarely searches using the exact language an author used while drafting. They may describe a reading mood, a type of protagonist, a setting, a relationship dynamic or a recognisable subgenre. Begin by asking what a suitable reader might type when they do not yet know the title.
That does not mean chasing the broadest phrase. A highly general term such as “fantasy book” says little about who the book is for. A more specific phrase can combine genre, audience and a genuine story feature.
Build a book-evidence map
Write down only what the book can support. Useful evidence usually comes from six areas:
- Primary genre and defensible subgenre
- Reader age or life stage where relevant
- Central relationship or conflict
- Setting and period
- Tone, pacing and emotional promise
- Distinctive subject matter or protagonist type
Keep evidence separate from aspiration. If the manuscript is a gentle, mystery-led cozy fantasy, metadata promising epic battles will attract the wrong reader even if the phrase appears commercially attractive.
Turn evidence into natural phrases
Combine two or three compatible elements. For example, a genre term can pair with a setting, protagonist or tone. Create more candidates than you need, then remove duplicates and phrases already communicated clearly by the title or subtitle.
Screen every candidate
Reject phrases that are misleading, excessively vague, unrelated to the manuscript or built around another author's identity. Avoid promotional claims and terms that imply qualities the book cannot substantiate. KDP's current guidance recommends relevant, specific choices rather than vague terms.
Do not treat keyword density as a target. The seven fields are metadata inputs, not miniature advertisements. Clear phrases are more useful than repeated variants padded with the same words.
Check the whole listing
Keywords work alongside the title, subtitle, categories, cover and description. If the cover signals romantic fantasy but the description reads as a procedural mystery, changing keywords alone will not repair the reader's experience. Resolve the positioning conflict first.
For a series, retain enough shared language to establish the shelf while giving each book room for its distinct hook. Identical entries across every title can waste opportunities to describe meaningful differences.
What to do next
- Create an evidence map.
- Draft 15–20 natural phrases.
- Remove repetition, unsupported promises and overly broad terms.
- Compare the remaining phrases with the cover and description.
- Choose the strongest entries and record why each belongs.
