KDP Keyword Generator
Seven backend keywords readers actually search
Amazon gives you seven keyword slots, and each one is a phrase, not a single word. The mistake most authors make is using broad terms they will never rank for. Describe your book and get seven long-tail phrases that match how a real reader types a search.
How do Amazon KDP keywords work?
You get seven keyword fields, and each holds a phrase of up to fifty characters. Amazon combines your keywords with words from your title, subtitle and categories, so you should not repeat those. The goal is to be discoverable for searches you can realistically rank for, which means specific phrases over broad ones.
Should I use single words or phrases?
Phrases. "Romance" has millions of competing books and you will never surface for it. "Small town enemies to lovers romance" is what a motivated reader actually types, and far fewer books target it, so you have a real chance of appearing.
What should I avoid in keywords?
Do not repeat words already in your title or category, do not use another author's name or trademarked terms, and do not stuff misspellings. Amazon prohibits some of these and ignores the rest, so they waste a slot you could spend on a phrase that works.
