Are you an author dreaming of that coveted "bestseller" tag on Amazon? The secret might not lie in your marketing budget or even your sales numbers—it could be all about choosing the right categories. In this comprehensive guide, we'll reveal how to strategically select Amazon book categories to maximize your chances of becoming a bestseller. Publisher Rocket's category search feature can significantly enhance your book's visibility by helping you find the best categories among over 12,000 available on Amazon.


Why Amazon Book Categories Matter

Amazon allows authors to select only 3 categories in KDP, making each category choice critically important for your book's visibility and success on the platform. Publisher Rocket simplifies the process of identifying potential categories, saving authors hours of manual searching.

Over time, Amazon has made significant changes to its category system, making it crucial for authors to stay informed and adapt their strategies to ensure optimal book placement and visibility.


Understanding Amazon's Best Seller Rank (ABSR)

Your book's success in any category depends on its Amazon Best Seller Rank (ABSR). Here's what you need to know:

  • ABSR updates every 2 hours

  • Lower numbers are better (ABSR #1 means you're the top seller)

  • Your ABSR determines your bestseller status within each category

  • You only need to beat the current #1 book's ABSR in your category to become the bestseller

With Publisher Rocket, you can see how many sales are needed to become a bestseller in any category, removing guesswork from the process.

The Three Category Secrets Amazon Doesn't Tell You

1. Duplicate Categories (54%)

Over half of Amazon's categories are duplicates, meaning they lead to the same page. While this might seem problematic, it can actually work in your favor:

  • Amazon prevents multiple selections of duplicate categories

  • Strong sales can help you rank in all duplicate category strings

  • This increases your book's visibility across different browsing paths

While duplicates might seem problematic, they can be advantageous if selected strategically. Publisher Rocket can help identify these duplicates and show where they are listed, allowing authors to maximize their book's visibility across different browsing paths.

2. Ghost Categories (27%)

These mysterious categories can hurt your bestseller chances:

  • They don't display a proper category name

  • No bestseller tags are available

  • Shoppers can't find these category pages

  • Selecting multiple ghost categories wastes your limited category choices

Ghost categories not only lack proper names and bestseller tags but are also invisible to shoppers, making them ineffective for book visibility. Selecting multiple ghost categories wastes your limited category choices and should be avoided. Publisher Rocket's Category Search helps spot ghost categories, ensuring authors avoid them to maintain effective book visibility.

3. Amazon's Category Control

They may place your book in additional categories based on:

  • Your selected categories

  • Keywords

  • Book description

  • Book content

Amazon may change your selected categories based on the keywords, book description, and content. To strengthen your claim to specific categories, use category-specific keywords in your metadata.
