How to Choose a Profitable Low-Competition Niche for Amazon KDP
Publishing on Amazon KDP offers an incredible opportunity to generate passive income, but success depends largely on choosing the right niche.
Many new authors fall into the trap of creating books in saturated markets or selecting topics with no real demand. The result? Poor visibility, low sales, and frustration.
In this guide, we’ll break down the essential criteria for selecting a profitable and low-competition niche — so you can increase your chances of ranking well, attracting readers, and earning steady royalties over time.
Why Niche Selection Is Critical
Amazon is a massive marketplace, but it’s also highly competitive. Without a smart niche strategy, your book can easily get buried beneath thousands of similar titles.
The right niche strikes a balance between demand and competition. Your goal is to find that sweet spot: a topic people are searching for, but where you can realistically compete and stand out.
Key Criteria for a Winning KDP Niche
Below are the most important factors to evaluate when choosing your KDP niche. These apply whether you’re publishing low-content books, activity books, nonfiction, or educational material.
1. Search Demand
A niche must have active search traffic on Amazon. If no one is looking for it, it doesn’t matter how good your book is.
How to evaluate:
- Use keyword tools (like Publisher Rocket or BookBeam) to estimate monthly searches.
- Check Amazon autocomplete suggestions to see what people commonly type.
- Browse “Customers also bought” sections for related books.
Look for niches that are:
- Specific but not obscure
- Common enough to show up in suggestions
- Present in multiple keyword variations
Tip: Use long-tail keywords such as “sudoku for seniors with large print” instead of just “sudoku”.
2. Low to Medium Competition
A niche may be popular, but if it’s overloaded with high-quality books, it will be difficult to rank without a large audience or ad budget.
How to evaluate:
- Type your main keyword into Amazon and note the number of results.
- Check how many books on page one have:
- BSR under 100,000 (they sell regularly)
- Over 100 reviews (high social proof)
- Strong covers and branding
A good low-competition niche often includes:
- Fewer than 1,000–3,000 results
- Only a few books with strong sales (BSR < 100k)
- Several outdated or poorly designed covers
Ideal competition level: moderate activity with noticeable gaps in quality or targeting.
3. Consistent Sales Volume (Across Titles)
One-hit wonders can mislead you. A niche with just one best-seller and dozens of flops is likely unstable.
How to evaluate:
- Use BSR tracking tools like KDSpy or Book Bolt to check historical rankings.
- Look for at least 3–5 books in the niche that consistently rank under 150,000 BSR.
This suggests broad market demand and a healthy buyer base.
4. Keyword Flexibility and Variants
The more keyword variations you can use, the easier it will be to rank for multiple terms and reach different buyer intents.
Signs of keyword flexibility:
- The niche supports plural/singular forms: “planner” vs. “planners”
- Can be combined with sub-niches: “gratitude journal for teens”, “fitness tracker for women”
- Supports seasonal or trend-based versions: “Christmas coloring book”, “Back to school checklist”
Strong niches allow you to build out series, themed collections, or branded bundles.
5. Category and Subcategory Availability
Check that your niche fits into relevant categories on Amazon. This improves visibility and helps you qualify for category best-seller ranks.
To verify:
- Browse through existing books in the niche and see what categories they use.
- Confirm that KDP allows those categories during upload.
- Preferably, find low-competition subcategories with active buyers.
You can request additional categories by contacting Amazon KDP support after publishing.
6. Audience Clarity
The clearer your audience, the easier it is to design, write, and market your book.
Ask yourself:
- Who is the buyer? (parent, teacher, student, senior?)
- What is their pain point or desire?
- Would they buy multiple books of this type?
Good niches have a clear, reachable buyer persona — and preferably one that spends frequently on Amazon.
7. Room for Differentiation
Even if a niche is slightly competitive, you can succeed if you offer something different.
Ways to stand out:
- Better design or illustrations
- Targeting an underserved demographic (e.g. left-handed kids, ESL learners)
- Adding bonus features (trackers, stickers, QR codes)
- Improving usability (e.g., large print, spiral binding, interactive pages)
Use customer reviews in your niche to find common complaints and create books that solve them.
Putting It All Together: A Sample Framework
| Factor | Good Niche Example | Bad Niche Example |
|---|---|---|
| Search Demand | “Handwriting practice for kindergarten” | “Poems about abstract geometry” |
| Competition | ~2,500 results, moderate BSR spread | 40,000+ results, all top books with 1,000+ reviews |
| Sales Volume | 5 books under 100,000 BSR | Only 1 book under 200,000 BSR |
| Keyword Variants | Many: handwriting, tracing, ABCs | Few to none |
| Audience Clarity | Parents and homeschoolers | Unknown |
| Differentiation Possible | Add tracing + coloring + reward chart | No room to innovate |
Final Thoughts
The success of your KDP publishing business depends on one thing above all: choosing the right niche.
Without strong demand, low competition, and room to serve an identifiable audience, even the most polished book can struggle to gain traction.
The good news? You don’t need to guess.
Use proven tools, follow a structured validation process, and stay focused on providing real value. Smart niche selection turns your books from digital noise into profitable, evergreen assets.
