Is KDP Still Worth It in 2026?
The honest answer
✅ YES — but the game has changed. Generic low-content books are dead. Medium-content and niche guides are alive and growing. AI makes it 10x faster. Volume is the key.
What's Working vs What's Dead
✅ What Works
- Medium-content books (puzzles, activity books)
- Niche-specific guides (AI tools, productivity)
- AI-assisted creation at volume
- Niche-down targeting (not broad categories)
- Series/bundles (Books 1-5 in a series)
❌ What's Dead
- Generic blank journals & notebooks
- Basic planners with no niche
- "Publish 1 book and retire"
- Copy-paste templates, no research
- Niches with 10,000+ competitors
Real Case Studies
€70.82 in Month 1 (Nov 2025)
Published 10 AI-generated books in 30 days using ChatGPT + Claude + Canva. On track to double in Month 2. Mix of guides, journals, activity books.
$3,200/month (Aug 2025, r/KDP)
Found low-competition niches using BSR 100K-500K sweet spot. Published ~40 books over 6 months. Avoided competing with bestsellers directly.
BSR 14,703 = 358 sales/month
Puzzle book with 27 reviews at $12.99. That's $500+/month from ONE book. Priced well to run ads profitably.
⚠️ The hard truth: The first $100 is the hardest. Most people quit before Month 3. 90% of success stories come from people who published 20+ books before seeing real traction.
Profitable Niches in 2026
Where the money actually is
Tier 1: High Profit, Recommended
🧩 Medium-Content Puzzle Books
LOW COMPETITIONWord search, crossword, sudoku, spot-the-difference, dot-to-dot. Evergreen demand, repeat buyers, automated creation.
- Word search for seniors / dog lovers / cat lovers
- Large print puzzles (seniors market is huge)
- Themed crosswords (sports, movies, food)
- Dot-to-dot for adults (stress relief angle)
🤖 AI Tools Guides — YOUR NICHE
LOW COMPETITIONYou use ChatGPT, Claude, Perplexity, Notion daily. That's your unfair advantage. Guides for specific tools aimed at specific audiences.
- ChatGPT prompts for online coaches (50-100 templates)
- Claude vs ChatGPT vs Gemini comparison guides
- Perplexity AI for research & writing
- AI tools for content creators / solopreneurs
- Notion AI setup guides + templates
🎨 Kids Activity Books
MEDIUM COMPETITIONSeasonal spikes (summer, holidays, back-to-school). Parents buy multiple. Travel/road trip angle = repeat purchasers.
- Road trip activity books (ages 6-8, 9-12)
- Dinosaur / unicorn / space themed
- Kindergarten readiness workbooks
📅 Hyper-Niche Planners
MEDIUM COMPETITIONNOT generic planners. Hyper-specific niches where fans will pay premium.
- Homeschool planners (growing market)
- Etsy seller business planner
- Fitness tracker for powerlifters
- AI content creator planner
Tier 2: Experimental
🍳 Niche Recipe Books
Angle matters: "5-Ingredient Air Fryer" or "Keto Meal Prep for Beginners." Don't do "Chicken Recipes" — way too broad.
📐 Educational Workbooks
Math by grade level, handwriting practice, language learning. Steady demand from homeschool market.
❌ Avoid These (Saturated)
- Blank lined journals (Amazon Basics competes)
- Generic composition notebooks
- Basic coloring books (unless VERY niche)
- Password logbooks (10,000+ titles)
- "Gratitude journal" — searched 1M+ times but 50K+ books
Low vs Medium vs High Content
Which type should you create?

Tools & Costs
What you actually need to spend
Essential (Month 1)
The gold standard for KDP research. Finds profitable niches, shows competition levels, suggests categories, reverse-engineers competitor keywords. No monthly fee = pays for itself fast.
Cover design + basic interior layouts. Free version works for covers. Pro unlocks premium templates and background remover.
ChatGPT for word lists, ideas, outlines. Claude for long-form guide content, editing, description writing. Both essential.
Format your manuscript for KDP. Set to 6x9 page size with KDP margins, download as PDF.
Optional (Month 2+)
Cloud-based alternative to Publisher Rocket + has interior creator for puzzles and activity books. Good if you want an all-in-one.
Only start ads after you have 10+ books and first organic sales. Ads on books with no reviews = wasted money.
Total Investment
| Scenario | Month 1 | Month 2-3 | Total 90 Days |
|---|---|---|---|
| Bare Bones | $97 (Rocket) | $0 | ~$100 |
| Recommended | $97 + $13 Canva | $150 ads + $26 Canva | ~$286 |
Break-even: At $1.50 avg royalty, you need ~200 sales total to recoup $300 investment. That's about 20 books × 10 sales = achievable by Month 4.

AI Content Rules (2026)
What Amazon requires — don't risk your account
⚠️ Important: Amazon KDP requires disclosure when AI content is used. There's a checkbox during upload. Always check it if you used AI. Amazon can detect it and will suspend accounts for non-disclosure.
✅ Safe to Do
- Use AI for drafts, then heavily edit
- ChatGPT to generate word lists for puzzles
- AI for book descriptions (not book itself)
- AI for brainstorming ideas
- Disclose honestly — just check the box
❌ Don't Do
- Copy-paste ChatGPT with zero editing
- Use AI images without disclosure
- Lie on the disclosure checkbox
- Publish content you haven't reviewed
Your Best Approach
For AI guides: AI-Assisted, not AI-Generated. You're the expert. Use AI to draft, then rewrite with your voice, experience, and real examples. This produces better books AND covers you legally.
For puzzle books: AI generates the word lists. You create the puzzles. Disclose AI was used in the process. Clear and compliant.
Your advantage: You actually USE these AI tools. Your guides will have real opinions, real workflows, real comparisons. ChatGPT can't fake that. That's why your AI guides will beat generic AI-generated ones.
Pricing Strategy
How to price for maximum royalty + conversions
⚠️ June 2025 royalty change: Amazon reduced paperback royalties. A book priced at $7.99 now earns ~$1.16 (down from $1.95). Price at $9.99+ to maintain healthy margins.
Paperback Pricing Sweet Spots
| Price | Printing Cost | Your Royalty | Sales Likelihood |
|---|---|---|---|
| $6.99 | ~$3.85 | ~$0.80-1.00 | ⭐⭐⭐⭐⭐ Impulse buy |
| $7.99 | ~$3.85 | ~$1.16-1.40 | ⭐⭐⭐⭐⭐ Best balance |
| $9.99 | ~$3.85 | ~$1.80-2.40 | ⭐⭐⭐⭐ Higher perceived value |
| $12.99 | ~$3.85 | ~$2.80-3.40 | ⭐⭐⭐ Needs good reviews |
Pricing by Book Type
Puzzle Books
Start at $7.99. Move to $9.99 after 10+ reviews. Large print puzzles can command $9.99 from day one (seniors willing to pay).
AI Guides
Start at $9.99-11.99. More content = higher perceived value. Buyers expect to pay more for "business books."
Activity Books
$6.99-7.99 for kids (parents impulse-buy). Gift versions can go $8.99-9.99.
Ebooks (If doing Kindle)
$2.99-9.99 for 70% royalty. Sweet spot = $4.99-6.99. Under $2.99 = only 35% royalty.
Strategy: Launch at $7.99. Get 5-10 reviews organically. Test $9.99. If sales don't drop — stay there. Higher price + same sales = more money.
Amazon Ads Strategy
When to start, how much to spend, what to target
🚫 Don't run ads in Month 1. Wait until you have 10+ books AND at least 3 reviews on a book. Ads on books with no social proof = money in Amazon's pocket, not yours.
When to Start (Month 2-3 Checklist)
- 10+ books published
- 2-3 books getting organic sales
- At least 3 reviews on target book
- Cover is professional (not amateur)
- Description is optimized with keywords
Beginner Ad Setup
Week 1-2: Automatic Targeting
- Budget: $5/day per book (max 3 books)
- Let Amazon find customers automatically
- Run for 14 days before analyzing
- Collect data: which search terms convert?
Week 3+: Manual Targeting
- Use winning keywords from automatic campaign
- Target competitor ASINs (show up on their listing)
- Increase budget on profitable campaigns
- Pause or kill unprofitable keywords
Key Metric: ACOS
| ACOS | Meaning | Action |
|---|---|---|
| < 30% | Very profitable | Scale up budget |
| 30-50% | Profitable | Maintain, optimize |
| 50-80% | Break-even zone | Improve listing, lower bids |
| > 80% | Losing money | Pause and fix listing first |
Mistakes to Avoid
How 90% of beginners fail — don't be them
❌ Mistake 1: Too Few Books
Publishing 5 books and expecting income. You need 20-30 to find your winners. Math: 5 books × 20% success rate = 1 winner. Not enough.
❌ Mistake 2: No Research
"I made a pretty journal" is not a strategy. Research BEFORE creating. Use Publisher Rocket. 30 minutes of research saves 10 hours of wasted creation.
❌ Mistake 3: Terrible Covers
Your cover IS your sales page. Amateur cover = instant scroll. Invest 2 hours in Canva. Look at bestseller covers in your niche and model them.
❌ Mistake 4: Generic Titles
"Word Search Book" = invisible. "Large Print Word Search for Dog Lovers: 100 Themed Puzzles" = specific, searchable, converts.
❌ Mistake 5: Wrong Keywords
KDP gives you 7 keyword slots. Most people waste them. Research what buyers actually search. Use exact phrases, not single words.
❌ Mistake 6: Quitting at Month 2
Most books take 30-90 days to gain traction. Amazon needs time to index. Reviews take time. The people who quit at Month 2 never see Month 4.
The #1 mistake: Publishing 6 books, getting 0 sales, and concluding "KDP is dead." That's not data. That's a sample size of 6. You need 20-30 data points.
Winning Patterns
What successful KDP publishers actually do
Pattern 1: Volume + Velocity
Successful publishers have 50-200+ books. Not 5-10. More books = more lottery tickets. Amazon also favors active publishers (algorithm boost).
Pattern 2: Niche Specialization
Winners dominate micro-niches. Not "word search puzzles" — too broad. "Large Print Word Search for Seniors with Dog Themes" = specific = less competition = better conversion.
Pattern 3: AI Workflow Mastery
Example: Puzzle Book in 2.5 Hours
- ChatGPT: "Give me 200 dog breed names for word search" — 5 min
- Puzzle software: Generate 50 puzzles — 90 min (automated)
- Canva: Design cover + page layout — 45 min
- KDP: Upload, write description, publish — 30 min
Pattern 4: Data-Driven Iteration
- Track BSR daily for first 30 days after publishing
- If BSR stays above 500K after 60 days: take down, fix, or abandon
- If BSR drops below 100K: double down (more books in that niche)
- Kill losers fast. Scale winners fast.
Pattern 5: Build in Public (Your Advantage)
Publishers who document their journey grow faster. Every KDP book = an X thread. "30 books in 90 days" = months of content. Your audience growth and KDP income compound together.
Your Competitive Advantage
Why you're better positioned than most beginners
🤖 AI Tools Expertise
You use ChatGPT, Claude, Perplexity, Notion AI daily. You have REAL experience, not theory. Your guides will have personality and actual insight that ChatGPT-slop books can't fake.
⚙️ Systems Thinker
KDP is a system: research → create → publish → optimize → repeat. You love processes, workflows, data. This is your game, not a writer's game.
🔁 Content Compound
Every KDP book = an X thread for @diogo_builds. KDP journey = months of content. Your audience growth and KDP income feed each other.
🛍️ Sales Background
You understand positioning, copywriting, objection handling. Book titles, descriptions, and pricing are all sales. You're ahead.
⏰ Dead Time Utilization
Pockets of 2-3 hours between sales calls. That's enough to create a full puzzle book or write 3,000 words of a guide. KDP doesn't need 8-hour blocks.
🤖 Tools Already Paid For
Claude Pro + ChatGPT = $40/mo you're already spending. That's your entire content creation toolkit. Most KDP beginners don't have this advantage.
