Step 01 · 1 hr
Pick a niche that actually sells
Niche selection is 80% of the outcome. Non-fiction how-to guides in specific niches dramatically outperform general topics. Categories that consistently sell on KDP: productivity for specific jobs (e.g. "Time Management for Nurses"), personal finance in life stages (e.g. "Money Habits for New Graduates"), pet-specific guides (e.g. "First Year with a French Bulldog"), and hobby deep-dives (e.g. "Beginner's Guide to Hydroponics").
Use Claude to validate your idea: *"I'm thinking of writing a short Kindle ebook titled '[Your Idea]'. Search Amazon and tell me: is this niche competitive? What do the top books cover? What gap could a new book fill?"* Claude can search the web to give you a real competitive picture.
Aim for a niche where the top 3 books have fewer than 500 reviews — that signals a real market without overwhelming competition.
Pro tip
Avoid fiction, poetry, or broad self-help. The KDP market for specific how-to niches is far less saturated and readers buy on specificity.
Step 02 · 2–3 hrs
Outline and write the ebook with Claude
A 5,000–10,000 word ebook is the sweet spot for KDP: long enough to feel substantial, short enough to write in a day. Aim for 6–8 chapters of roughly 700–1,200 words each.
Start with the outline: *"Create a 7-chapter outline for a Kindle ebook titled '[Your Title]'. Each chapter should have a clear goal and 4–5 key points. The target reader is [describe them]. Tone: practical, direct, no fluff."*
Then write chapter by chapter: *"Write Chapter 1: [Title]. 900 words. Conversational but authoritative tone. Start with a relatable scenario, then deliver the insight. No generic advice."* Repeat for each chapter.
Add an introduction (200 words: who this is for + what they'll learn) and a conclusion (200 words: recap + clear next step).
Pro tip
Read each generated chapter before continuing to the next. Ask Claude to revise anything that feels generic or padding-heavy. Quality beats length.
Step 03 · 30 min
Format your ebook for Kindle
Kindle readers are forgiving of simple formatting. The most reliable approach: write in Google Docs with heading styles (Heading 1 for chapter titles, normal text for body), then export as DOCX. KDP converts DOCX cleanly.
Formatting checklist: - Remove all manual line breaks (use paragraph spacing instead) - Use Heading 1 for chapter titles, Heading 2 for sub-sections - No tables or complex layouts — they break on older Kindle devices - Include a table of contents (Google Docs > Insert > Table of contents) - Page count doesn't matter — Kindle reflowable format adjusts to device
KDP also accepts EPUB if you prefer. Use Calibre (free) to convert DOCX → EPUB with finer control.

Design a professional cover in Canva
The cover is the single biggest driver of clicks in Amazon search results. A bad cover kills an otherwise good book.
In Canva, create a custom design at 2,560 × 1,600px (KDP Kindle cover dimensions). Choose a template from Canva's "Book Cover" category as your starting point — look for clean, modern layouts with bold title typography.
Cover formula that works: bold title text (40% of the cover), a relevant visual or abstract background, and your author name at the bottom. Keep it simple — covers that try to say too much look amateurish at thumbnail size.
Ask Claude for cover copy: *"Write 3 subtitle options for a Kindle ebook titled '[Title]'. Each under 12 words. Should communicate the specific outcome the reader gets."* The subtitle often appears on the cover and always in the KDP title field.
Export as JPEG at maximum quality.
Pro tip
Download the final cover at the full 2,560 × 1,600px resolution. KDP will reject covers below their minimum quality threshold.
Step 05 · 1 hr
Set up your KDP account and publish
Go to kdp.amazon.com and sign in with your Amazon account. Click "+ Kindle ebook" to start a new title.
Key fields to fill carefully: - Title + subtitle: Use your strongest keyword in the title (e.g. "Hydroponics for Beginners: A Step-by-Step Guide to Growing Food at Home with No Experience") - Author name: Use a pen name if you prefer — this is public on Amazon - Description: 150–250 words. Open with the reader's problem, then your book's solution. Ask Claude: *"Write an Amazon KDP book description for '[Title]'. 200 words. Problem → solution → who it's for → what they'll learn. No hype."* - Keywords: 7 keyword phrases (not single words). Target phrases people search: "beginner hydroponics guide", "grow vegetables at home no soil", etc. - Categories: Choose 2 — as specific as possible. Narrow categories = easier to rank - Pricing: Set $2.99 to unlock the 70% royalty tier. This is the sweet spot for discoverability and income.
Upload your DOCX manuscript and JPEG cover. Preview in the Kindle previewer before submitting.
Pro tip
The 70% royalty tier applies to books priced $2.99–$9.99 in most markets. At $2.99 with 70% royalties, you earn ~$2.07 per sale. 50 sales/month = ~$100.

Drive your first reviews and long-term sales
KDP review takes 24–72 hours. Once live, your book needs reviews to rank in Amazon search. Path to first reviews: share your book link with people who'd genuinely find it useful — your network, relevant Reddit communities (check sub rules), relevant Facebook groups, or your newsletter if you have one.
Enrol in KDP Select (exclusive to Amazon for 90 days) to access Kindle Unlimited — a subscription library where you earn per page read. KU readers add meaningful passive income for non-fiction how-to guides.
Run a free promotion (KDP Select perk) on days 3–5 after publishing. Free downloads generate real reader reviews. 100–500 downloads in a free promo with even 5–10 reviews following gives you social proof to compete organically.
The long-term play: publish 3–5 titles in related niches. Income compounds — each title feeds the others via the "Customers also bought" algorithm.
Frequently asked questions
Bottom line
Ship it.
Amazon KDP is one of the few genuine $0-startup passive income plays still available — no inventory, no publisher, no upfront cost, and royalties land on a schedule. The barrier is niche selection and cover quality, not writing skill. Claude handles the writing; Canva handles the cover. The honest caveat: most first ebooks earn modest income until you have reviews and multiple titles compounding. Treat the first title as your education and publish with that expectation. The second and third titles benefit from everything you learned.
