Free KDP Keyword Generator: Keyword Ideas for Your Book

The right keywords help readers find your book on Amazon. This free KDP keyword generator turns your topic and book type into dozens of keyword ideas, plus a starter set for the seven keyword boxes in your KDP dashboard.

How to use this generator

  1. Type your main topic, for example “sudoku” or “gratitude”.
  2. Choose your book type: puzzle book, journal, planner, coloring book or non-fiction guide.
  3. Add your audience if you want audience-based phrases, such as “adults” or “teachers”.
  4. Tap any phrase to copy it.

What are KDP keywords?

When you publish on KDP, you can enter seven keyword boxes, and each box holds up to 50 characters. Amazon uses these phrases, along with your title, subtitle and description, to understand what your book is about and which searches it should appear for.

How to choose good keywords

  • Use phrases buyers type. “Large print sudoku for adults” is more useful than “puzzles”.
  • Don’t repeat words from your title. Use the boxes for new phrases that add meaning.
  • Mix short and long phrases. Long phrases are easier to match with a clear buyer intent.
  • Stay accurate. Only use phrases that describe your book. Avoid brand names, author names and unrelated terms.
  • Check Amazon autocomplete. Type each idea into the Amazon search bar. Phrases that appear in suggestions are good candidates.

Keyword ideas are not search volumes

This tool creates ideas from common patterns. It does not show how many people search for each phrase. Validate your favorites with Amazon’s search suggestions and by looking at what similar books rank for.
