Best KDP Categories for New Books (Low Competition)

The best KDP categories for new books are the ones where the top 10 bestsellers have relatively low BSRs (Best Seller Ranks above 50,000) and where you won't be competing against household-name authors. In practice, that means targeting sub-subcategories in niches like self-help journals, niche cookbooks, activity books, and specialized non-fiction rather than broad genres like "Thriller" or "Romance." Pick the right category and your book can hit a bestseller tag within the first week. Pick the wrong one and you'll be invisible on page 47 forever.

What Makes a KDP Category "Low Competition"

A low-competition category has three characteristics:

• The #1 bestseller has a BSR above 30,000-50,000. This means even the top book in that category isn't selling a massive number of copies daily. You can realistically compete.
• Few or no books from major publishers. If the top 10 is filled with Big Five titles, walk away. You want categories dominated by indie authors and small presses.
• The category has at least 200-500 total books. Too few books means there's no real demand. Too many means you'll drown. The sweet spot sits in the middle.

A common mistake is chasing empty categories. A category with 12 books and no sales isn't "low competition." It's "no demand." There's a difference, and it matters.

Specific Low-Competition Categories Worth Targeting in 2025

Here are real category niches where new authors are consistently finding traction:

• Self-Help > Journaling: Guided journals, gratitude journals, and shadow work journals continue to sell well. The category is broad enough to support new entrants but specific enough that you're not fighting against every self-help book ever written.
• Cookbooks, Food & Wine > Regional & International > [Specific Cuisine]: "Mexican Cooking" is competitive. "Oaxacan Cooking" is not. The deeper you go into regional subcategories, the easier it gets.
• Children's Books > Activities, Crafts & Games > Activity Books: Coloring books, maze books, word searches for kids. These have healthy demand, and the top spots turn over regularly.
• Business & Money > Small Business > Home-Based: Niche business guides for specific audiences (Etsy sellers, freelance writers, mobile notaries) do surprisingly well here.
• Religion & Spirituality > Devotionals: Devotional journals and prayer guides for specific demographics (new moms, teens, men) often sit in categories with BSRs above 80,000 for the #1 spot. That's very achievable.
• Computers & Technology > Software-Specific Guides: Guides for specific tools (Notion, Obsidian, specific programming frameworks) land in thin categories where even modest sales push you to the top.

These aren't the only options. They're starting points. Your best category will depend on your book's actual content, not on someone else's "best niches" list.

How to Research Categories Before You Publish

Don't guess. Every category decision should be backed by data.

Start by searching Amazon for books similar to yours. Look at where they're categorized. Click into those category pages and check the BSRs of the top 20 books. Write those numbers down. If the #1 book has a BSR under 10,000, that category is probably too competitive for a brand-new book with zero reviews.

Next, check how many of those top books have over 100 reviews. A category where half the top 10 has 500+ reviews signals an established market where readers already have trusted favorites. That's a tough place to break in.

Tools like the Category Optimizer on PublishRank can speed this process up significantly. It analyzes category competitiveness and helps you identify browse nodes that match your book's content without requiring hours of manual Amazon browsing.

The Two-Category Strategy

Amazon gives you two category slots when you publish through KDP. Use them strategically.

Put your book in one category that's a close content match with moderate competition. This is your "relevance" pick. Amazon's algorithm will associate your book with the right audience here, which helps with also-bought recommendations and organic discovery.

Your second slot should be your "winnable" pick. A smaller, less competitive subcategory where a few sales per day can land you the orange bestseller badge. That badge creates social proof, which drives more clicks, which drives more sales. It's a flywheel.

You can also request up to 10 categories total by contacting KDP support after publishing. Not every request gets approved, but it's worth asking. Target 3-5 additional categories where your book legitimately fits. Don't spam irrelevant categories. Amazon has gotten better at removing books from categories where they don't belong.

Categories to Avoid as a New Author

Some categories are traps for new books. Stay away from these unless you have an existing audience or a serious marketing budget:

• Kindle Store > Romance > Contemporary: Tens of thousands of books. The top sellers move hundreds of copies daily. You'll be buried instantly.
• Literature & Fiction > General: This is the catch-all dumping ground. Nobody browses here intentionally. Your book will sit in a sea of millions.
• Any top-level category without a subcategory: "Self-Help" alone has over 100,000 books. "Self-Help > Stress Management > Anxiety" has a fraction of that. Always go deeper.
• Categories dominated by free/KU books: If the top 10 are all Kindle Unlimited titles priced at $0.99-$2.99, competing with a $14.99 paperback is an uphill battle.

When to Change Categories

Your initial category choice isn't permanent. In fact, you should revisit it.

If your book has been live for 30 days and hasn't cracked the top 100 in either category, something's off. Either the categories are too competitive, or your book's metadata (title, subtitle, description) doesn't align with what shoppers in those categories expect.

Seasonal shifts matter too. A "Summer Cocktail Recipe" book should be in different categories in June than in December. A "Tax Preparation Guide" peaks in Q1. Adjust accordingly.

Check your category performance monthly for the first 90 days. After that, quarterly is fine unless you're running a promotion or launching a new book in the same series.
