KDP Metadata Guidelines: Title, Subtitle, Keywords & Categories Checklist

A practical checklist for KDP metadata compliance—how to reduce rejection risk and avoid common mistakes in titles, subtitles, keywords, categories, and descriptions.

Published: 2026/01/14Updated: 2026/01/14

This page is a quick compliance checklist for KDP metadata. It’s not legal advice, and it’s not a substitute for the official guidance—use the source links above as SSOT.

The quick takeaway

Metadata is often reviewed as a package:

  • Your title/subtitle/series should be accurate and consistent with the manuscript.
  • Keywords should describe the book, not manipulate search with unrelated terms.
  • Categories should match what readers will actually get.

Checklist (high-signal items)

Title & subtitle

  • Avoid stuffing: the title shouldn’t be a keyword paragraph.
  • Keep capitalization consistent and readable.
  • Don’t include pricing, promotional text, or ranking claims in the title.

Keywords

  • Keywords should describe what the book is (topic, genre, audience).
  • Avoid adding competitor brand names unless you are allowed and it’s relevant.
  • Avoid misleading keywords that do not appear in the book.

Categories

  • Choose categories that match reader expectations.
  • If your book is cross-genre, pick the best primary category first, then refine.
