🎯

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

1

€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.

2

$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.

3

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 COMPETITION
Price: $7.99-9.99
Royalty: $1.40-1.80
Creation: 3-4 hrs

Word 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 COMPETITION
Price: $9.99-12.99
Royalty: $2.40-3.20
Creation: 5-8 hrs

You 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 COMPETITION
Price: $6.99-8.99
Royalty: $1.10-1.60
Creation: 5-6 hrs

Seasonal 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 COMPETITION
Price: $8.99-14.99
Royalty: $1.50-3.50
Creation: 4-5 hrs

NOT 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?

📓 Low Content

Blank journals, simple notebooks, basic planners

⚠️ Near-dead in 2026. Skip unless unique twist.

🧩 Medium Content ⭐️

Puzzles, activity books, coloring, mazes

✅ Sweet spot. Harder to make = less competition. AI makes it fast.

📚 High Content

Full guides, nonfiction, comprehensive how-tos

✅ Higher royalty but 10-30hr creation time. Do 1-2 in your niche.

Recommended Mix for Your 30 Books

AI Tools Guides (High Content)40% = 12 books
Puzzle Books (Medium Content)40% = 12 books
Activity Books (Medium Content)20% = 6 books

💸 Amazon Ads Budget $5-15/day (Month 2+)

⚠️

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

PricePrinting CostYour RoyaltySales 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

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.
