What is Amazon KDP?

Amazon Kindle Direct Publishing (KDP) is a self-publishing platform by Amazon. It allows authors to publish eBooks and paperbacks for free. When someone buys your book, Amazon prints and delivers it — and you earn royalties without needing any upfront inventory.

Things to Prepare Before Starting

1. Choose Your Topic and Unique Angle

Select a topic you know well and that has market demand. A unique angle makes your book stand out — use your own experiences, case studies, or exclusive data to make it original.

2. Write and Format Your Manuscript

Write your book in Microsoft Word (.docx) or Google Docs. KDP supports .doc, .docx, and PDF, but .docx is preferred for Kindle reflow formatting. Ensure consistent font size, spacing, and use proper headings.

3. Respect Copyright and Originality

Always write in your own words. If you use any references, paraphrase properly and cite your source to avoid copyright issues.

Formatting: Manuscript and Cover

Manuscript Tips

• Use clean fonts like Times New Roman or Arial.
• Maintain consistent paragraph spacing and margins.
• Use Heading 1 and Heading 2 styles for easy Table of Contents generation.
• Use high-resolution images and include proper ALT text.

Cover Design

Your cover is your first impression. You can design it using Canva, Affinity Designer, or Photoshop. Follow Amazon’s cover size and spine width guidelines.

2. Fill out your account information, including payment details, tax information, and address.
3. Verify your identity and enable two-step verification for security.

Book Listing: Title, Description, Keywords, Categories

Title & Subtitle: Make them clear and searchable. Include your main keyword naturally.

Description: Amazon allows basic HTML tags in descriptions. Start with an engaging hook, then use bullet points to explain what readers will learn, and finish with your author bio.

Keywords & Categories
    
Use relevant, long-tail search phrases for your 7 keyword fields. Choose 2 main categories that fit your niche — Amazon may also assign subcategories automatically.

    
Pricing, Royalties, and KDP Select
    
KDP offers two royalty options: 35% and 70%. The 70% rate applies if your eBook is priced between $2.99 and $9.99 and meets other criteria. For paperbacks, printing costs are deducted before calculating your royalty.
    
KDP Select: Optional program offering promotional tools like Free Book Promotions and Kindle Unlimited (page-read-based income). In return, your eBook remains exclusive to Amazon for 90 days.

Amazon Ads: Run Sponsored Product or Lockscreen Ads to drive initial sales.
      
Free Days & Reviews: Use KDP Select Free Days to gain reviews and visibility (avoid fake reviews).
      
SEO: Use natural keywords in your title and description for better Amazon ranking.
    

    
How to Avoid Duplicate Content
    

      
Never copy-paste from other books or websites.
      
If repurposing your own blog content, rewrite and expand it. Add new chapters, data, or stories.
      
Maintain a unique title, subtitle, and cover design.
    

    
Using Copyright-Free Images (and Adding Them in HTML)
    
Use trusted sources like Unsplash, Pexels, and Pixabay for free commercial-use images.
    

      
Search for terms like “book mockup”, “author writing”, or “reading coffee”.
      
Download the image and upload it to your website instead of hotlinking.
      
Add it in HTML as shown below:

</figure>
    
Tip: Always host the image on your own site to avoid copyright or broken link issues.
