Whether you're just starting on KDP or have dozens of books live, certain mistakes cost you sales, trigger rejections, and in some cases lead to account suspension. Here are the 15 most common — and how to avoid every one.
Publication Mistakes
1. Skipping the KDP Print Previewer
The most frequent mistake. You submit, the book gets approved, you order a proof — and the margins are cut off, pages are misaligned, or fonts are wrong.
Fix: Always download and review the print preview before submitting. For your first book in any new trim size, order a proof copy ($3–5). It's worth every penny.
2. Wrong Cover Dimensions
Your cover must match the exact page count AND paper size. The spine width changes based on page count — even a 10-page difference affects it.
Fix: Use the KDP Cover Calculator for every new project. Never reuse a cover from another book without recalculating the spine width.
3. Low-Resolution Images
Blurry cover or interior images. KDP requires a minimum of 300 DPI for clean print output.
Fix: Always export at 300 DPI from Canva or your design tool. Images pulled from the internet (72–96 DPI) are unusable for print — they'll look sharp on screen but blurry in print.
4. Trademarked Words in Title or Keywords
Using terms like "Disney," "Marvel," "Pokémon," or "Harry Potter" in your title, subtitle, or keywords can trigger immediate rejection or account suspension.
Fix: Stay in your niche without referencing any brand. If your book is about cats, you don't need to name a cat brand. Describe the content, not the association.
5. Medical or Financial Guarantees in Your Description
Writing "This journal will cure your anxiety" or "Make $5,000/month with this method" violates Amazon's content guidelines.
Fix: Use factual, benefit-driven language without guarantees: "A daily reflection space to help manage stress and build consistency."
SEO Mistakes
6. Repeating Your Title in All 7 Keywords
Many beginners copy words from their title into all 7 keyword fields. Amazon already indexes your title — this wastes your most valuable search real estate.
Fix: Use all 7 keyword fields for complementary terms not in your title or subtitle. Think about alternative searches your target reader might use.
7. Choosing Overly Broad Categories
Selecting "Self-Help" or "Business" puts you against hundreds of thousands of books. You'll be invisible.
Fix: Find specific subcategories where you can realistically reach the top 10 with lower competition. A #1 bestseller badge in a specific niche drives more organic sales than being #50,000 in a general category.
8. Generic Title with No Keywords
A title like "My Planner" or "Daily Journal 2026" won't be found by anyone searching on Amazon.
Fix: Include your primary keyword in the title. "Blood Pressure Log Book for Seniors — Daily Tracker with Medication Notes" explains exactly what it is and gets found in search.
Marketing Mistakes
9. Waiting for Organic Sales Without Advertising
Expecting organic sales on a new book with no reviews and no sales history is extremely difficult. Amazon's algorithm favors books that already have sales.
Fix: Allocate a minimum of $60–90/month for an Auto KDP Ads campaign during the first 30 days. Initial sales from ads improve your organic ranking and visibility.
10. Ignoring A+ Content
Available for free after publication, A+ Content can increase your conversion rate by 5–20%. The majority of KDP authors never create it.
Fix: 24–72 hours after your book is approved, create your A+ Content (KDP → Marketing → A+ Content). Use Amazon's built-in AI generator as a starting point — it takes 15 minutes.
11. Publishing Without Any Reviews
A book with 0 reviews converts significantly worse. Even 3–5 honest reviews make a measurable difference.
Fix: Use KDP's "Request a Review" button in your dashboard — it automatically sends an Amazon-approved review request to buyers. It's 100% within Amazon's terms of service.
Account Management Mistakes
12. Publishing Near-Duplicate Content (Content Recycling)
Publishing 10 versions of the same journal with only cover color changes can be flagged as duplicate content and trigger a suspension.
Fix: If creating variants, make sure the interior content is substantially different for each version. Change the structure, prompts, sections, or page design — not just the cover.
13. Using Images Without Commercial Rights
Images from Google, Pinterest, or a random free site are not yours to use. Using them on a cover or in your interior can trigger DMCA claims and book removal.
Fix: Only use sources with explicit commercial licenses: Pexels, Unsplash (check individual licenses), Adobe Stock, your own Midjourney creations (check commercial terms), or images you created yourself.
14. Not Monitoring Your BSR and Adapting
Publishing and forgetting. A book can slowly lose its ranking while you're not watching.
Fix: Check your KDP dashboard at least once a week. If a book is declining, investigate: new competition? Seasonal shift? Ads underperforming? Act before the decline becomes permanent.
15. Quitting After One or Two Books
Most authors stop after their first or second book, often after 30 days of modest results.
Fix: KDP is a catalog game. Ten to twenty books in complementary niches generate exponentially better revenue than a single book. Your first few books teach you what works — they're tuition, not the business.
