Publishing random books and hoping they sell is gambling. Systematic niche research is how top KDP publishers consistently find profitable opportunities with low competition. This guide teaches the exact 5-step methodology: category mining, competition analysis, keyword opportunity scoring, profit margin calculation, and trend evaluation. No more guessing—just data-driven decisions.
⚠️ Why Most Niche Advice Fails
Generic niche lists like "publish coloring books" or "journals are profitable" are useless because:
- Too broad: "Coloring books" has millions of results—you'll drown in competition
- Already saturated: By the time a niche hits a blog list, 10,000 publishers have flooded it
- No methodology: You learn what to publish, not how to find opportunities yourself
This guide teaches the research process, not just a list of niches. Master this system once, use it forever.
The 5-Step KDP Niche Research System
Follow these steps in order. Skipping steps = publishing books that don't sell.
Step 1: Category Mining (Find Opportunity Pockets)
Goal: Identify specific sub-categories within broad niches where demand exists but competition is manageable.
How to Mine Categories on Amazon
- Start with a broad category you're interested in (e.g., "Coloring Books," "Journals," "Word Search Puzzles")
- Browse Amazon Best Sellers in that category:
amazon.com/Best-Sellers-Books - Click into sub-categories 2-3 levels deep:
- Too broad: "Books › Arts & Photography › Drawing"
- Just right: "Books › Arts & Photography › Drawing › Coloring Books for Grown-Ups › Animals"
- Look for patterns in top 100: What themes repeat? (e.g., "Ocean animals," "Farm animals," "Exotic animals")
- Note bestseller rankings (BSR): Books ranked #5,000-50,000 are the sweet spot—selling well but not impossibly competitive
Example: Coloring Book Niche Mining
❌ Too Broad (Don't Stop Here):
- "Coloring Books for Grown-Ups" — 50,000+ results, top books have 10,000-20,000 reviews
✅ Profitable Sub-Niches (Drill Down Here):
- "Ocean Animals Coloring Books for Ages 4-8" — 2,000 results, top books have 200-500 reviews
- "Large Print Mandala Coloring Books for Seniors" — 800 results, top books have 150-300 reviews
- "Swear Word Coloring Books for Adults" — 1,500 results, top books have 300-800 reviews
Key Insight: Niche down until you find categories with 500-5,000 results and top books with 100-500 reviews (not 10,000+).
Step 2: Competition Analysis (Assess Difficulty)
Goal: Determine if you can realistically compete in this niche based on bestseller rank, review counts, pricing, and book quality.
Key Metrics to Analyze
Open 10-20 top books in your target sub-niche and record these data points:
| Metric | Where to Find It | What You Want to See |
|---|---|---|
| BSR (Best Seller Rank) | Product details section | #5,000-50,000 = good demand #50,000-200,000 = moderate demand Over #200,000 = weak demand |
| Review Count | Below title (e.g., "4.5 out of 5 stars, 324 ratings") | 100-500 reviews = competitive but achievable 1,000-5,000 reviews = very competitive 10,000+ reviews = avoid (established monopoly) |
| Pricing | Listed price on product page | Consistent pricing ($9.99-14.99 for most low-content) Avoid if top books are priced at $5.99 or less (race to bottom) |
| Cover Quality | Thumbnail image | Amateur covers = opportunity to outcompete with professional design All pro covers = harder to stand out |
| Page Count | Product details (e.g., "Paperback: 104 pages") | Standard for niche (don't publish 50 pages if competitors have 100+) |
| Publish Date | Product details | Mix of recent (2023-2025) and older books = healthy, active niche All books from 2018-2020 = dying niche |
Scoring System: Is This Niche Winnable?
Rate each factor on a 1-5 scale (5 = best for you):
- BSR: 5 = Most top 20 books ranked #5K-30K | 1 = Most under #100K
- Reviews: 5 = Under 500 reviews | 1 = Over 2,000 reviews
- Cover Quality: 5 = Many amateur covers | 1 = All pro covers
- Pricing: 5 = Consistent $10-15 pricing | 1 = Price war under $7
- Recency: 5 = Many 2024-2025 books | 1 = Mostly pre-2020 books
Total Score Interpretation:
- 20-25 points: Green light—publish here!
- 15-19 points: Yellow light—possible but requires excellent execution
- Under 15 points: Red light—move on to another niche

Create Winning CoversStep 3: Keyword Opportunity Scoring
Goal: Find specific keywords within your niche that have search volume but low competition.
How to Find Keywords
- Amazon Search Autocomplete (Free):
- Type your niche into Amazon search: "ocean animal coloring book"
- Amazon suggests completions: "ocean animal coloring book for toddlers," "...for kids," "...for adults"
- These are real searches with demand—Amazon wouldn't suggest them otherwise
- Competitor Keyword Mining:
- Look at titles of top 20 books in your niche
- Extract repeated keywords: "large print," "easy," "relaxing," "stress relief," "seniors"
- These are proven keywords that drive sales
- Publisher Rocket (Paid Tool - $97 one-time):
- Enter seed keyword (e.g., "mandala coloring book")
- Get search volume estimates, competition scores, and related keywords
- Worth the investment if serious about KDP (pays for itself after 2-3 book sales)
Keyword Opportunity Formula
For each keyword, calculate the Opportunity Score:
Opportunity Score = (Search Volume / 1000) × (1 / Number of Competing Books)
Example 1: "large print coloring book for seniors"
- Search Volume: 8,000/month
- Competing Books: 1,200
- Score: (8000 / 1000) × (1 / 1200) = 0.0067
Example 2: "ocean coloring book"
- Search Volume: 12,000/month
- Competing Books: 8,500
- Score: (12000 / 1000) × (1 / 8500) = 0.0014
Higher score = better opportunity. Target keywords with scores above 0.005.
Step 4: Profit Margin Calculation
Goal: Ensure the niche supports profitable pricing after accounting for printing costs and Amazon's royalty structure.
KDP Royalty Math
Amazon pays you 60% of list price minus printing costs.
Example: 8.5×11 Coloring Book, 104 pages, Black & White Interior
- List Price: $12.99
- Amazon's 60% Share: $12.99 × 0.60 = $7.79
- Printing Cost: ~$3.65 (varies by page count and trim size)
- Your Royalty: $7.79 - $3.65 = $4.14 per sale
To calculate for your book: Use Amazon's Royalty Calculator
Pricing Sweet Spots by Niche
- Coloring Books (8.5×11, 50-100 pages): $9.99-14.99 (royalty: $3-5)
- Word Search / Puzzle Books (8.5×11, 100-150 pages): $8.99-12.99 (royalty: $2.50-4)
- Journals / Planners (6×9, 100-120 pages): $7.99-11.99 (royalty: $2-3.50)
- Fiction Paperbacks (6×9, 200-300 pages): $12.99-16.99 (royalty: $3-5)
- Non-Fiction (various sizes, 150-250 pages): $14.99-24.99 (royalty: $4-8)
Red Flag: If competitors in your niche are priced under $7.99 and you can't match that price profitably (due to printing costs), skip this niche. Price wars destroy margins.
Step 5: Evergreen vs. Trend Evaluation
Goal: Distinguish between sustainable niches (evergreen) and temporary fads (trends) to decide publishing strategy.
Evergreen Niches (Long-Term Passive Income)
Characteristics: Consistent demand year-round, not tied to specific events or fads.
Examples:
- Sudoku puzzles for seniors
- Gratitude journals
- Recipe organizers
- Budget planners
- Drawing tutorials for kids
How to verify evergreen: Use Google Trends
- Go to trends.google.com
- Search your niche keyword (e.g., "mandala coloring book")
- View 5-year trend: Flat or slowly growing line = evergreen | Huge spike then crash = fad
Trending Niches (High Risk, High Reward)
Characteristics: Sudden surge in demand tied to news, pop culture, or seasonal events.
Examples:
- Fidget toys coloring books (2017-2018 fad—dead now)
- Among Us activity books (2020-2021 peak—declining)
- Bridgerton-themed journals (Netflix show hype—temporary)
- Holiday-specific planners (December spike, dead by February)
When to Publish Trends vs. Evergreen
| Factor | Evergreen Strategy | Trend Strategy |
|---|---|---|
| Time Investment | Worth spending 1-2 weeks on quality | Speed matters—publish in 2-5 days max |
| Portfolio % | 80% of your catalog should be evergreen | 20% max—diversify risk |
| Expected Lifespan | 2-5+ years of sales | 3-12 months of sales |
| Competition | Moderate, consistent over time | Low initially, floods within weeks |
| Pricing Power | Stable, can maintain $10-15 pricing | Erodes fast—price drops as competition grows |
Recommendation: Build your income foundation on evergreen niches. Chase trends only if you can publish within days of spotting the opportunity (before saturation).

Common Niche Research Mistakes
❌ Mistake #1: Stopping at Broad Categories
Publishing a generic "Coloring Book" or "Journal" is a guaranteed path to $0 sales. Always niche down 2-3 levels: "Dinosaur Coloring Book for Boys Ages 6-8 with Facts" beats "Dinosaur Coloring Book."
❌ Mistake #2: Ignoring Pricing Realities
Seeing competitors priced at $6.99 when your printing costs require $10.99 minimum = unprofitable niche. Do the math BEFORE creating content.
❌ Mistake #3: Chasing Dead Fads
A trend from 2-3 years ago is already flooded and dying. Use Google Trends to verify demand is current, not historical.
❌ Mistake #4: No Keyword Research
Creating a book without keyword research = hoping Amazon magically shows it to customers. Won't happen. Keywords drive discoverability—invest 30 minutes researching them.
Final Takeaway: Research Once, Publish Confidently
Most KDP publishers fail because they skip niche research and hope for the best. Top earners spend 80% of their time on research, 20% on creation. This 5-step system transforms publishing from a gamble into a predictable, profitable process:
- Category Mining: Drill down 2-3 levels to find opportunity pockets
- Competition Analysis: Score niches to assess difficulty (aim for 20+ points)
- Keyword Opportunity: Find high-volume, low-competition keywords (score above 0.005)
- Profit Calculation: Verify pricing supports $3-5 royalties minimum
- Evergreen vs. Trend: Build 80% of catalog on evergreen, chase trends sparingly
Master this system once, and you'll never run out of profitable book ideas. The publishers earning $5,000-10,000/month aren't lucky—they're systematic. Start researching today, and publish your first data-backed book this week.
