KDP Keywords and Categories Strategy: Rank and Succeed

Short answer

To fill the KDP keyword slots effectively, use relevant phrases that describe your book's content, themes, and audience. For categories, choose those that reflect your book's genre and give it the best chance to rank by considering popularity and competition levels.

How to Fill the 7 KDP Keyword Slots

Optimizing your KDP keywords can significantly impact your book's visibility on Amazon. Here’s how you can effectively fill those seven keyword slots:

  1. Understand Your Audience: Knowing your readers is crucial. Are they young adults, professionals, or hobbyists? Use tools like Publisher Rocket to identify high-traffic keywords. For instance, if you're writing a cookbook, determine if your audience is looking for quick meals, gourmet recipes, or diet-specific options.
  1. Use Long-tail Keywords: These are specific phrases that your potential readers might type into the search bar, such as “historical fiction for teens” or “easy vegetarian recipes.” For example, if your book is about urban gardening, a long-tail keyword could be “how to grow vegetables in a small apartment.” This specificity helps target niche audiences more effectively.
  1. Incorporate Synonyms: Include variations of your main keywords to reach a broader audience. If your book is about “mindfulness meditation,” consider synonyms like “awareness exercises” or “conscious relaxation.” This approach captures different search intents and increases discoverability.
  1. Avoid Repetition: Amazon treats each slot independently, so avoid repeating words across slots. For example, if you have “romantic thriller” in one slot, avoid using “thriller” again in another. Instead, use related terms like “suspenseful romance” to diversify your reach.
  1. Focus on Relevance: Ensure that all keywords are directly related to your book's content. Irrelevant keywords can mislead readers and lead to negative reviews. If your book is a science fiction novel, avoid keywords related to fantasy unless there's a significant overlap in themes.
  1. Analyze Competitor Keywords: See what successful books in your genre are using. For example, if a top-selling mystery novel uses “whodunit” and “detective story,” consider how these might apply to your book. Tools like Helium 10 can assist in this analysis.
  1. Test and Adjust: Monitor your book’s performance and make changes if needed. If a particular keyword isn’t driving traffic, replace it with a new one. Use Amazon’s search bar suggestions to find trending keywords related to your genre.

How to Choose Book Categories on Amazon

Choosing the right categories can make or break your book's success. Here’s a step-by-step guide:

  1. Research Popular Categories: Use Amazon's category browser to see where similar books are listed. Start by searching for books similar to yours and note their categories. For example, a self-help book might be listed under “Personal Development” or “Motivational.”
  1. Consider Competition: Aim for categories with moderate competition. Too much competition can bury your book. Use tools like KDP Rocket to gauge how many books are in a category and how many sales are needed to rank well.
  1. Leverage Niche Categories: If your book fits a niche, it can be easier to rank. For example, a book on vegan bodybuilding might perform better in “Vegan Diets” rather than the broader “Health & Fitness” category.
  1. Check Category Rankings: Tools like KDP Rocket can help you see how many sales are needed to rank in certain categories. This insight allows you to set realistic sales goals and adjust your marketing strategy accordingly.
  1. Select Two Categories: Amazon allows you to choose two categories initially, but you can request to be added to more by contacting support. This flexibility can help you test different market segments and optimize for the best results.

What are Amazon Book Keywords?

Amazon book keywords are phrases that help readers find your book during their search. They should be relevant and targeted to your audience’s search habits.

How to Optimize:

  • Use a mix of broad and specific terms. For instance, combine “fantasy” with “dragon adventure” for a fantasy novel.
  • Avoid using author names or book titles unless they are highly relevant. This ensures that your keywords focus on the content and themes of your book rather than specific identifiers.

The Importance of KDP 7 Keywords

The seven keyword slots you fill out during your KDP setup are crucial for discoverability. Each slot can contain multiple words, so use them wisely. This is where tools like Atticus or Reedsy can support your research process by providing insights into keyword effectiveness and trends.

Understanding Book Categories on Amazon

Why Categories Matter:

  • Visibility: Proper categorization helps readers find your book. A well-chosen category aligns with your book’s themes and audience, making it more likely to appear in relevant searches.
  • Sales Potential: Being in the right category can increase your chances of ranking, which boosts sales. For example, ranking in a niche category might require fewer sales than a broader one, yet still significantly boost your book's visibility.

How to Maximize Impact:

  • Regularly review your category placement. Market trends and reader interests change, so periodically reassess your categories to ensure they remain the best fit.
  • Use Amazon’s browse categories to find the most fitting options. Experiment with different combinations and track their impact on your sales and visibility.

Practical Example of Keyword and Category Selection

Let’s say you’re publishing a children’s picture book about space exploration:

  • Keywords: “kids space book”, “space adventure for children”, “educational space books.” These keywords are specific and cater to parents looking for educational yet entertaining content for their children.
  • Categories: Children’s Books > Science, Nature & How It Works > Astronomy & Space; Children’s Books > Growing Up & Facts of Life > Friendship, Social Skills & School Life. Choosing these categories aligns your book with educational themes and developmental topics, enhancing its appeal to parents and educators.
