Amazon KDP (Kindle Direct Publishing) lets anyone publish books — ebooks and paperbacks — and sell them on Amazon, the world’s largest bookstore. No publisher, no agent, no upfront printing costs. This guide covers everything a beginner needs to start.
What is Amazon KDP?
KDP is Amazon’s free self-publishing platform. You upload your book files, set a price, and Amazon handles printing, shipping, and customer service for paperbacks — and instant delivery for ebooks. You earn royalties on every sale.
There are two main formats:
- Kindle ebooks — read on Kindle devices and the free Kindle app. Royalty: 35% or 70% depending on price and enrollment in KDP Select.
- Paperbacks — print-on-demand. Amazon prints each copy only when someone orders it. You never touch inventory. Royalty: 60% of list price minus printing costs.
What Sells on KDP? (Low-Content Books)
Many beginners start with low-content books — journals, planners, puzzle books, coloring books, and logbooks. These have minimal written content and are faster to create than full-length books.
Popular low-content categories:
- Puzzle books — sudoku, crosswords, word searches, nonograms. Huge, evergreen demand.
- Coloring books — for kids and adults. Themes matter: animals, mandalas, affirmations.
- Journals and planners — lined, dotted, gratitude journals, habit trackers.
- Activity books — mazes, dot-to-dot, and mixed puzzle collections for kids.

Step 1: Create Your KDP Account
Go to kdp.amazon.com and sign up with your Amazon account. It is free. You will need to enter tax information and bank details for royalty payments — Amazon pays monthly, about 60 days after the month of sale.
Step 2: Create Your Book
You have three paths:
- Make it yourself — tools like Canva, BookBolt, or Affinity Publisher for interiors; free to low-cost.
- Use AI tools — a growing number of products generate puzzle books, coloring pages, or journal interiors with AI. (We review several on Pickzox.)
- Hire a designer — on Fiverr or Upwork, $20–$100 for a quality low-content interior.
Critical rule: your content must be original or properly licensed. Uploading unchanged PLR can get your KDP account terminated — Amazon requires significantly original content. If you use PLR as a starting point, heavily transform it.
Step 3: Format to KDP Specifications
Amazon is strict about technical requirements:
- Paperback interiors: PDF, with correct trim size (common: 8.5″ x 11″ for activity books, 6″ x 9″ for journals), margins, and bleed settings.
- Covers: separate PDF for paperbacks (front, spine, back as one file) — KDP provides a cover template calculator.
- Kindle ebooks: EPUB, MOBI, or DOCX; reflowable or fixed-layout.
KDP’s built-in previewer shows exactly how your book will look. Always check every page in the previewer before hitting publish — formatting errors are the #1 reason for bad reviews.
Step 4: Publish Your Book
In your KDP dashboard, click “Create” and fill in:
- Title, subtitle, and description — include keywords buyers search for. This is your most important marketing.
- Categories — choose up to 3. Pick the most specific, least competitive categories you genuinely fit.
- Keywords — 7 keyword slots. Use phrases buyers type, not single words (“large print sudoku for seniors” beats “puzzle”).
- Price — for paperbacks, $6.99–$12.99 is typical for low-content books. Check competitors’ pricing.
After submitting, review takes 24–72 hours. Then your book is live on Amazon worldwide.
Step 5: Get Reviews and Sales
Publishing is half the battle. To sell:
- Optimize your listing — great cover, keyword-rich title, compelling description with bullet points.
- Amazon Ads — start with $5/day automatic campaigns targeting competitor books. This is how most KDP sellers get initial traction.
- Publish more books — the #1 predictor of KDP income is catalog size. Each book promotes the others through “also bought” recommendations.
- Never buy fake reviews. Amazon detects and bans for this. Earn reviews honestly — include a polite review request inside your book.
Common Beginner Mistakes
- Skipping niche research. Publishing a generic “lined journal” into a category with 100,000 competitors is invisible. Use Amazon’s search bar autocomplete and tools like Publisher Rocket to find niches with demand but manageable competition.
- Weak covers. Buyers judge books by covers — especially online. A blurry or amateur cover kills sales no matter how good the interior is. Invest here.
- Keyword stuffing the title. “Sudoku Puzzle Book Large Print Easy Medium Hard Seniors Adults” looks spammy and Amazon penalizes it. Write a natural title with 1–2 keywords.
- Publishing one book and waiting. One book rarely earns much. Plan for at least 10 books in your first few months — volume is the strategy.
- Ignoring the interior quality. For puzzle books, test every puzzle. For journals, check alignment on every page. One-star reviews from sloppy interiors are hard to recover from.
Realistic Expectations
Honest numbers for beginners:
- One low-content book typically earns $10–$100/month once ranked.
- Sellers earning $1,000+/month usually have 20–50+ books published.
- Your first books teach you the process; later books earn more because you are better at keywords, covers, and niches.
- Timeline: expect 3–6 months of consistent publishing before meaningful income.
KDP is a real business, not a lottery ticket. The sellers who succeed treat it like one: research niches, publish consistently, and reinvest in ads and better covers.
Frequently Asked Questions
Is KDP really free?
Yes — publishing costs nothing. Amazon takes its cut from royalties only when you sell. Your costs are optional: design tools, ads, and any outsourcing you choose.
Can I publish PLR on KDP?
Risky. Amazon requires original content and actively removes books that are repackaged PLR. If you use PLR at all, transform it substantially — new design, rewritten content, unique arrangement. Many sellers have lost accounts over this.
Do I need an ISBN?
No. Amazon assigns a free ASIN to every book, which is all you need to sell on Amazon. A dedicated ISBN only matters if you want to sell through bookstores outside Amazon.
How much do KDP authors actually make?
It varies enormously. Most beginners earn little at first. Consistent publishers with 30+ quality books commonly report $500–$5,000/month. Top sellers earn far more. Your niche selection and publishing volume matter most.
Can I publish from outside the US?
Yes. KDP is available worldwide. Royalty payments go to your bank account in most countries; where direct deposit is unavailable, Amazon can hold earnings until thresholds are met.
