Publishing children’s books on Kindle Direct Publishing (KDP) can be a rewarding endeavor. However, to ensure your book reaches its target audience, it’s essential to choose the right categories and keywords. In this article, we’ll guide you through the process of selecting categories and keywords that will help your children’s book stand out on KDP.

Choosing Categories

  1. Understand Your Book’s Genre: Before selecting categories, understand the genre and theme of your children’s book. Is it a picture book, a middle-grade novel, or a young adult story? Knowing this will narrow down your category choices.
  2. Research Categories: Visit the KDP dashboard and explore the available categories for children’s books. You’ll find options like Children’s Picture Books, Children’s Fantasy Books, and Children’s Non-Fiction Books.
  3. Select Relevant Categories: Choose categories that closely match the content and age group of your book. Don’t try to fit your book into unrelated categories, as this can lead to low visibility and confused readers.
  4. Use Subcategories: KDP allows you to select two categories for your book. Make use of both if they are relevant. For example, if your book is a picture book about animals, you might select “Children’s Picture Books” and “Children’s Books about Animals.”

Picking Keywords

  1. Brainstorm Keywords: Think about words or phrases that accurately describe your book. Consider character names, settings, themes, and any unique elements. For a children’s book about a magical adventure with talking animals, keywords might include “magic adventure,” “talking animals,” and “fantasy for kids.”
  2. Use Relevant Phrases: Instead of single words, focus on keyword phrases. These are more likely to match what potential readers are searching for. For instance, “funny bedtime stories for kids” is more precise than just “funny.”
  3. Competitive Analysis: Look at other successful children’s books in your chosen categories. What keywords are they using? This can provide valuable insights and help you discover relevant keywords you may have missed.
  4. Utilize All Available Slots: KDP allows you to enter seven keywords or keyword phrases. Use all of them to maximize your book’s discoverability. Don’t waste space with keywords that aren’t directly related to your book.
  5. Avoid Keyword Stuffing: While it’s crucial to use relevant keywords, avoid stuffing your description with them. Your book’s description should read naturally and be appealing to potential readers.

Ongoing Optimization

  1. Monitor Sales and Rankings: Keep an eye on your book’s performance. If you’re not getting the visibility or sales you expected, consider revising your categories and keywords.
  2. Update as Needed: You can change your book’s categories and keywords on KDP. If you discover better keywords or if your book’s focus changes over time, don’t hesitate to make updates.
  3. Stay Informed: The world of online publishing is dynamic. Stay informed about trends in children’s literature and adjust your keywords and categories accordingly.


Selecting the right categories and keywords for your children’s book on KDP is essential for attracting the right audience and maximizing your book’s visibility. Remember to choose categories that accurately represent your book’s genre and content, and use relevant, well-researched keywords to increase discoverability. With careful selection and ongoing optimization, your children’s book can find its place in the digital marketplace and captivate young readers around the world.
