You’ve written a book. Maybe it took months. Maybe it took years. Either way, you’re now staring at the Amazon KDP dashboard wondering what on earth a BISAC code is, why “metadata” keeps appearing in every forum thread you visit, and whether you genuinely need to understand DPI before you can publish.
The good news: you don’t need to know everything. You need to know the right things, in the right order.
This is the guide to read before any other. It covers the complete self-publishing journey on Amazon Kindle Direct Publishing — from account setup to understanding why a book that’s already live might not be gaining traction. Every topic links out to a dedicated deep-dive article when you’re ready to go further. Bookmark it and work through it at your own pace.
What Amazon KDP Actually Is
Amazon KDP (Kindle Direct Publishing) is Amazon’s self-publishing platform. It lets authors publish eBooks, paperbacks, and hardcovers and sell them directly on Amazon — without a literary agent, a traditional publisher, or a minimum print run. When a reader buys your book, Amazon handles the transaction, prints the physical copy if required, manages fulfilment, and pays your royalties roughly 60 days after the end of the month in which the sale occurred.
There is no upfront cost to publish. Amazon earns its money through a percentage of each sale. This makes KDP a genuinely low-risk entry point for first-time and independent authors. For a detailed explanation of how the platform works mechanically, see our guide to what Amazon KDP is and how it works.
KDP vs traditional publishing
Traditional publishing involves submitting your manuscript to publishers — usually via a literary agent — waiting months or years for a decision, and, if accepted, receiving an advance against royalties that typically sit between 10% and 15% of net sales. The process can take two years or more from contract to bookshop shelf, and the vast majority of submissions are rejected.
With KDP, you earn between 35% and 70% per sale, retain full rights, control your own pricing and cover, and can be live in under 72 hours. The trade-off is that editing, cover design, and marketing are your responsibility to fund and manage. For a full breakdown of the differences, read our KDP vs traditional publishing comparison.
Formats: eBook, Paperback, and Hardcover
KDP supports three publishing formats. The right choice depends on your genre, your audience’s reading habits, and your pricing strategy. Most authors publish in at least two formats simultaneously. For a full breakdown of the options, see our guide to what formats you can publish on KDP.
Kindle eBook
eBooks are delivered instantly to any device running the free Kindle app — smartphones, tablets, Kindle e-readers, and computers. There are no printing costs, which means lower overheads and higher royalties. Most new KDP authors begin here. eBooks work particularly well for fiction, business books, and non-fiction titles that don’t rely on complex or heavily illustrated layouts.
Paperback
KDP’s paperback option uses print-on-demand (POD) technology. A copy is printed only when a reader orders it — there is no minimum print run, no stock to hold, and no upfront printing cost. Quality is consistently good, though it varies slightly between Amazon’s printing facilities. For a detailed look at how this works, see our article on KDP print-on-demand explained.
Hardcover
KDP added hardcover publishing in 2021. The process mirrors paperback publishing but hardcovers support higher price points and higher printing costs. They suit gift books, illustrated reference titles, and non-fiction where perceived authority matters. Not all titles are eligible — KDP flags this during setup. For help choosing between the two print formats, read our guide to KDP hardcover vs paperback.
| Format | Royalty | Price for max rate | Best for |
|---|---|---|---|
| Kindle eBook | 70% | $2.99 – $9.99 | Fiction, narrative non-fiction, business |
| Kindle eBook | 35% | Below $2.99 / above $9.99 | Permafree lead magnets |
| Paperback | 60% minus print cost | Above minimum threshold | All genres; non-fiction particularly |
| Hardcover | 60% minus print cost | Above minimum threshold | Gift books, illustrated titles, prestige non-fiction |
Setting Up Your KDP Account
Go to kdp.amazon.com and sign in with your existing Amazon account or create a new one. Before you can receive royalties, you need to complete your tax information — US authors submit a W-9, non-US authors complete a W-8BEN. Amazon is legally required to collect this before making payments, and the form takes around five minutes. You’ll also need to add a bank account for royalty transfers.
For a step-by-step walkthrough of the full setup, including how to configure your payment settings and tax interview, see our guide to how to set up your KDP account. For non-UK and non-US authors, our guide to KDP for non-US authors covers territory-specific considerations including withholding tax treaties.
Author Central
Once your KDP account is live, set up an author profile at Amazon Author Central. This is a separate system from your KDP dashboard — it’s your public-facing author page, where you manage your biography, author photo, and book list. Readers who click your name on any Amazon product page land here. It’s free, takes 20 minutes to complete properly, and has a measurable effect on how credible and professional your author presence appears. For full instructions, see our article on how to link your KDP and Author Central accounts.
Preparing Your Manuscript
KDP accepts manuscripts in .docx, .epub, .pdf, .html, and several other formats. For most authors, uploading a Word document is the most straightforward approach — KDP’s conversion engine handles the transformation to Kindle format. For print books, a properly formatted PDF gives you the most control over the final output.
Before you upload, your manuscript must meet KDP’s formatting requirements. The most common issues that cause file rejection or poor rendering are covered in full in our KDP manuscript formatting requirements checklist. The most frequent culprits are:
- Incorrect margins — KDP has minimum margin requirements that vary by format and page count
- Images below 300 DPI in print files, which print poorly and trigger quality warnings
- Headers and footers that conflict with KDP’s automatic page number insertion
- Embedded fonts not licensed for embedding
- Inconsistent heading styles that break automatic table of contents generation
Amazon’s free Kindle Create tool handles most of these issues automatically for straightforward fiction or basic non-fiction. For guides to formatting specific formats, see our articles on how to format a KDP eBook and how to format a KDP paperback. For details of what needs to go at the front and back of your book, read our guide to front and back matter for KDP books.
Is your manuscript ready to publish?
Reader reviews are permanent, and errors discovered after publication are both costly to fix and damaging to your reputation. Before your manuscript goes anywhere near KDP, it needs a professional check. Vappingo’s book manuscript proofreading service pairs you with experienced editors who understand the specific demands of self-published books — catching everything from typos and punctuation errors to inconsistencies in character names, timeline, and formatting. Get it right before it goes live.
Your Book Cover: The Most Important Marketing Asset You Have
Amazon is a visual marketplace. Your cover competes in search results alongside titles produced by professional art directors at major publishing houses. A poor cover signals a poor book — readers make visual judgements in under a second, and no amount of great writing overcomes a cover that looks amateurish in a thumbnail.
KDP accepts cover files as JPEG or TIFF at a minimum of 1,000 pixels on the shortest side and 1,600 on the longest. The recommended dimensions are 2,560 × 1,600 pixels. For paperback and hardcover, you need a full-wrap cover file that includes front, spine, and back. For guidance on what works and why, read our articles on what makes a good book cover for Amazon and how to design a book cover for KDP without design skills. If you’re working to a budget, our guide to hiring a book cover designer on a budget covers your options realistically.
When briefing any designer, study the top 20 bestsellers in your specific category on Amazon first. Your cover needs to fit the visual conventions of your genre while standing out within it. A cover that looks like it belongs to a different genre actively suppresses your conversion rate.
Royalties and Pricing
Understanding how KDP royalties work before you set your price is essential — the difference between the two royalty tiers is significant enough to affect your entire pricing and advertising strategy. Our dedicated guide to how Amazon royalties work (35% vs 70%) covers every scenario in detail.
eBook royalties
KDP offers two tiers. The 70% tier applies when your book is priced between $2.99 and $9.99 (or local currency equivalent) in the markets where Amazon offers 70%. Price outside this band and your royalty drops to 35%. At the 70% tier, Amazon also deducts a delivery fee of approximately $0.15 per megabyte — negligible for text-only books, more significant for large illustrated files.
Most fiction authors price Kindle eBooks between $2.99 and $6.99. Most non-fiction authors sit between $4.99 and $9.99. For strategy on how to set the right price, see our article on how to price your book for maximum royalties.
Paperback royalties
Paperback royalties work differently: you receive 60% of your list price, minus Amazon’s printing cost. Printing costs vary by page count, trim size, and whether the interior is in black-and-white or colour. KDP’s royalty calculator, available during the pricing stage of book setup, shows your exact take-home at any price point before you commit.
KDP Select vs Wide Publishing
This is one of the most consequential strategic decisions a KDP author makes. Our dedicated article on KDP Select vs wide publishing covers every angle, but here is the core trade-off.
Enrolling in KDP Select means your eBook is exclusive to Amazon for rolling 90-day periods. In return, your book is included in Kindle Unlimited — Amazon’s subscription service — where you earn a royalty based on pages read from the KDP Select Global Fund. You also gain access to Kindle Countdown Deals and Free Book Promotions. For a detailed guide to running promotions effectively, see our articles on how to use Kindle Countdown Deals and how to run a KDP free promotion effectively.
Wide publishing means distributing your eBook across multiple platforms simultaneously — Apple Books, Kobo, Google Play, and others — using an aggregator like Draft2Digital or uploading to each platform directly. This removes KU income but opens significant additional markets. For a full platform comparison, read our guide to KDP vs IngramSpark vs Draft2Digital.
Keywords: How Readers Find Your Book
Amazon is, at its core, a search engine for products. When a reader types “cosy mystery set in Cornwall” into the search bar, Amazon’s algorithm scans book metadata — titles, subtitles, and seven backend keyword fields — to decide which results to show. Your keywords are the bridge between a reader’s search intent and your book’s product page. This topic is covered in depth in our complete guide to Amazon KDP keyword research.
KDP gives you seven keyword fields, each accepting up to 50 characters. Effective keywords are phrases, not single words. “Mystery” is noise in a catalogue of millions. “Amateur sleuth cosy mystery English village” is signal. Amazon’s autocomplete is your most accessible free research tool — begin typing any phrase into Amazon’s search bar and note the completions. Those suggestions are drawn from real search behaviour by real readers. For specific guidance on choosing your backend keywords, see our article on how to choose your 7 KDP backend keywords.
Getting keywords right manually takes significant time and research. A dedicated KDP publishing tool like KDP Fuel by Vappingo generates 100 targeted keyword ideas for your specific book, alongside an optimised book description and category recommendations — replacing hours of manual research with a process that takes minutes.
Categories and BISAC Codes
Every book on Amazon belongs to at least one category — up to three, if you request additional placements from KDP support after publishing. Categories determine which bestseller lists your book is eligible for and how Amazon surfaces it during browse journeys. The full strategy is covered in our guide to how to choose the best Amazon KDP categories for your book.
The most common category mistake is choosing the broadest available option. “Romance” contains hundreds of thousands of titles. “Scottish Highland Romance” is a fraction of that size, and achieving a #1 Bestseller badge in it — real social proof that influences purchasing decisions — is a realistic goal for a new author. For full guidance on this strategy, read our article on how to get your book into a #1 bestseller category. For the relationship between keywords and categories — a common source of confusion — read our article on KDP keywords vs categories.
Your Book Description: The Hardest 400 Words You’ll Write
After your cover, your book description is your most important conversion asset. A reader who clicks through to your Amazon page has already shown interest — the description’s job is to turn that interest into a purchase. Amazon allows up to 4,000 characters and supports a limited set of HTML tags for formatting. The complete strategy for writing a high-converting description is in our guide to how to write an Amazon book description that actually sells.
For genre-specific guidance, we have dedicated articles on writing descriptions for fiction, non-fiction, romance, thrillers and mystery, and self-help books. If your description is already live and not converting, our article on how to rewrite a failing book description walks through a systematic diagnostic process.
The four principles that apply regardless of genre:
- Lead with your strongest hook. The first two lines appear above the “Read more” fold on mobile. If they don’t compel the reader to continue, nothing below them matters.
- Establish what’s at stake. What does your protagonist stand to lose? What specific problem does your non-fiction book solve — and for exactly whom?
- Build urgency. Fiction descriptions typically close with a cliffhanger question. Non-fiction descriptions close with a clear statement of the transformation the reader will experience.
- End with a direct call to action. “Scroll up and download your copy today” is direct, functional, and consistently effective across categories.
The Publishing Process: Step by Step
Once your manuscript, cover, and metadata are ready, the publishing process itself is straightforward. For a complete step-by-step walkthrough of each screen in the KDP dashboard, see our KDP dashboard walkthrough. Here is the sequence at a high level:
Log in to your KDP account and click “Create a New Title”. Select your format — eBook, Paperback, or Hardcover. If you want all three, you create a separate entry for each, which you then link together as a series if applicable.
Title, subtitle, series information, author name, description, keywords, and categories. This metadata determines discoverability. For a detailed guide to uploading your manuscript correctly, see how to upload your manuscript to KDP.
Upload your manuscript and cover files. KDP generates a preview — use it. Check every chapter and every page on both the eBook and print previewer. What you see here is what your readers will see. For guidance on what to look for, see our article on how to preview your book before publishing.
Review your royalty estimate at your chosen price in each territory before proceeding. Click publish and wait for Amazon’s review — typically 24 to 72 hours. For a full explanation of what happens next, see our article on what happens after you hit publish on KDP.
What to Do in the First 30 Days After Publishing
Amazon’s algorithm gives new books a brief period of elevated visibility — a launch window that rewards early sales velocity. Using this window effectively has a measurable impact on long-term algorithmic positioning. Our article on why new books get a sales boost and how to use it covers the mechanics in detail.
Get your first reviews
Reviews are the single most influential factor in a reader’s decision to buy. A book with no reviews presents a significant barrier, particularly for an unknown author. For legitimate, terms-of-service-compliant review strategies, read our honest guide to getting reviews as a new author and our article on how to use ARC advance review copies on Amazon.
Start your Amazon advertising
Amazon Advertising — accessible through the Amazon Ads console — is the most direct way to drive targeted traffic to your book page. Even a small daily budget generates data about which search terms are converting, which you can use to refine your organic keyword strategy. Our beginner’s guide to Amazon Ads for authors covers setup, targeting, and bidding strategy from scratch.
If Your Book Isn’t Selling: What to Check
A book that isn’t selling is not necessarily a bad book. More often it’s a discoverability or conversion problem — something in the metadata, cover, description, or pricing is creating friction. Our dedicated guide on why your book isn’t selling on Amazon and how to fix it walks through a full diagnostic. Start with this checklist:
- Cover: Does it look competitive against the top 20 books in your specific category? Get honest feedback from readers in your genre — not friends and family.
- Keywords: Have you used all seven keyword fields? Are you targeting search phrases readers actually use, or generic single words with no specificity?
- Categories: Are you in appropriate categories with realistic competition levels? Have you requested your full allocation of three categories from KDP support? Read our guide on how to request additional categories from Amazon.
- Description: Does your opening sentence compel a reader to continue? Does the description close with a call to action? Is it using HTML formatting for readability?
- Price: Are you priced competitively for your category, format, and page count? Read our article on how your book’s price affects sales on Amazon.
- Reviews: Do you have enough reviews for a reader to feel confident buying from an author they don’t yet know?
- Amazon Best Seller Rank: Understanding your BSR and what it means is covered in our guide to what the Amazon Best Seller Rank is and how to improve it.
