The Problem

Why most KDP authors struggle with this.

Amazon gives you 2 category slots in KDP. Most authors pick the most obvious ones - which are dominated by books with thousands of reviews. You'd need to sell 200 copies a day to hit top 100. There are better categories, less obvious ones with lower competition where your book could realistically rank. You just don't know they exist.

Without Category Finder:

  • ✗ You're making decisions based on guesses
  • ✗ Your competitors have data you don't
  • ✗ You're losing sales every day to avoidable mistakes

With Category Finder:

  • ✓ Find subcategories where top 100 is achievable for your book
  • ✓ Understand exactly how many daily sales each ranking requires
  • ✓ Discover hidden categories your competitors are quietly using
  • ✓ Learn how to request up to 10 categories (most authors only have 2)
The Solution

How PublishRank solves it.

Enter your book's topic and we search Amazon to find the subcategories where similar books rank well. We score each category for competition level, showing you the estimated daily sales needed to hit top 100. We also show you the email trick to get into up to 10 categories - most KDP authors don't know this is possible.

How it works.

Three steps from sign-up to insight.

1

Describe your book's topic

Enter a topic, keyword, or niche. We find the Amazon subcategories where books like yours appear.

2

We score each category

We analyze competition, average review counts of top books, and BSR thresholds.

3

Pick your best opportunities

Choose 2–3 high-opportunity categories and request them via KDP support email.
