Amazon KDP What Is It: Platform Introduction for New Authors

Okay so Amazon KDP is basically Amazon’s self-publishing platform and honestly it’s probably the easiest way to get a book in front of actual buyers without dealing with traditional publishers or agents or any of that gatekeeping stuff. KDP stands for Kindle Direct Publishing and yeah it started as just ebooks but now you can do print books and even audiobooks through ACX which is connected to the whole ecosystem.

Here’s the deal – you upload your manuscript, set your price, and Amazon handles literally everything else. The printing, the shipping, the customer service, all of it. You get paid royalties which range from 35% to 70% depending on how you price your book and which territories you’re selling in. I’ve been doing this for like seven years now and the platform has changed SO much but the core concept is still the same.

Let me back up because you’re probably wondering what you actually need to get started. First thing is you need an Amazon account, obviously. But you’ll create a separate KDP account at kdp.amazon.com and it’ll ask for tax information because the IRS needs to know about your royalties. If you’re in the US you’ll fill out a W-9, international authors do a W-8BEN. Takes like ten minutes and yeah it’s annoying but you only do it once.

The platform lets you publish two main types of books – ebooks and paperbacks. Ebooks go live on Kindle devices and the Kindle app which is on basically every phone and tablet now. Paperbacks are print-on-demand which means Amazon doesn’t print your book until someone actually orders it. No upfront costs, no inventory sitting in your garage, none of that. I remember when I published my first book I was so paranoid about the print quality but honestly Amazon’s POD is pretty solid for the price point.

Oh and another thing – there’s this program called KDP Select which is like an exclusivity thing. If you enroll your ebook in Select you can’t sell it anywhere else (no Apple Books, no Kobo, whatever) but you get access to KU which is Kindle Unlimited. KU is this subscription service where readers pay like $12 a month and can borrow unlimited books. You get paid based on pages read, currently it’s around $0.004 per page but that fluctuates monthly based on the global fund Amazon sets aside.

The Select decision is honestly one of the biggest debates in self-publishing. I do both – some books are in Select because they perform better there, others I keep wide so I can sell on multiple platforms. For your first book though? I’d probably go wide just to see where your readers actually are. You can always enroll in Select later, it’s a 90-day commitment and then it auto-renews unless you opt out.

Formatting is where people get stuck and honestly it’s not as scary as it seems. For ebooks Amazon accepts Word docs, PDFs, ePubs, and a few other formats. Most people just use Word which is fine for basic books. If you’ve got a novel with simple formatting you literally just upload your Word doc and KDP converts it. The previewer tool lets you see how it’ll look on different devices before you publish.

Paperback formatting is slightly more involved because you gotta think about trim size (like 6×9 is standard for most genres), margins, headers, page numbers, all that print stuff. I use Vellum for my books now because it does everything automatically but it’s Mac only and costs like $250. There’s also Atticus which is newer and works on PC, that’s around $150 one-time payment. If you’re on a budget you can use free tools like Reedsy’s book editor or even format in Word if you’re careful with the margins and bleed settings.

Wait I forgot to mention covers – you need a cover and please don’t use the KDP cover creator tool unless you’re doing this as like a school project or something. It screams amateur and readers judge books by covers more than anyone wants to admit. You can get decent pre-made covers on sites like Go On Write or Self Pub Book Covers for like $50-100. Custom covers from actual designers run $200-500 usually. I’ve used both and honestly for my low-content books the pre-mades work fine but for my fiction I always hire a designer.

The metadata part is super important and people skip over it. When you’re setting up your book you’ll enter the title, subtitle if you have one, description, categories, and keywords. Categories are limited to two on the KDP dashboard but you can email support and ask for up to ten total. Keywords are seven phrases you can use to help readers find your book. Don’t waste them on obvious stuff that’s already in your title – think about what readers would actually search for.

Pricing strategy is its own whole thing. For ebooks between $2.99 and $9.99 you get 70% royalty in most countries. Below $2.99 or above $9.99 drops you to 35%. There’s also delivery costs for the 70% tier based on file size but unless you’ve got a massive cookbook with tons of images it’s usually negligible. Paperbacks you set the price but you have to cover Amazon’s printing costs first – a 200-page 6×9 paperback costs them around $3-4 to print, you get 60% of the list price minus printing costs. So if you price at $10.99, minus $3.50 printing, you get 60% of $7.49 which is like $4.49 per sale.

This is gonna sound weird but I actually test different prices on the same book sometimes. You can change your price whenever you want on KDP and it updates within like 12 hours usually. I’ve found that some books sell better at $4.99 than $2.99 even though they’re more expensive because readers associate higher prices with higher quality. But that’s genre-dependent and audience-dependent so your mileage may vary.

One thing nobody tells you is that your book doesn’t just magically get traffic when you publish it. Amazon has literally millions of books and yours is one of them. You need reviews to get traction, you need sales velocity to rank in categories, you need visibility somehow. I spent my first year thinking I just needed to write good books and they’d sell themselves – nope. Marketing is half the job, maybe more than half honestly.

The review system is tricky because Amazon has gotten super strict about it. You can’t pay for reviews, you can’t swap reviews with other authors, you can’t have your friends and family review unless they actually bought it with their own money. There’s a program called Kindle Unlimited All-Stars or Early Reviewer Program… actually wait that got discontinued. Now there’s Kindle Countdown Deals and Free Book Promotions if you’re in Select, those can help generate some initial reviews.

Oh and Kindle Vella is this serialized fiction platform Amazon launched a few years ago. It’s episodic content where readers buy tokens to unlock episodes. I tested it with a thriller series and it was… okay. Not amazing but not terrible. The audience is pretty small compared to regular Kindle but if you write romance or fantasy it might be worth experimenting with.

The dashboard shows you sales in real-time which is both awesome and dangerous because you’ll refresh it like forty times a day when you’re starting out. Trust me, I still do it and I’ve got 200+ books published. You can see units sold, pages read from KU, royalties earned, and it breaks down by marketplace since KDP distributes to Amazon US, UK, Germany, France, Spain, Italy, Japan, Canada, Australia, India, and a few others.

Author Central is separate from KDP but you should set it up – it’s where you create your author page, add your bio, link your social media, follow your sales rank. Sales rank is addictive to watch, it updates hourly and shows how your book ranks against every other book on Amazon. Lower is better, like #1 is the bestselling book on Amazon overall. Most books hang out in the six-figure range which sounds bad but there are millions of books so even ranking #500,000 means you’re selling a few copies here and there.

One more thing about the actual publishing process – when you hit publish it takes like 72 hours for your book to go live, sometimes faster. Ebooks are usually up within 24 hours, paperbacks take longer because they do a manual review. Once it’s live you can update files whenever you want which is great for fixing typos or updating covers. The changes take another review period but your book stays live during the update.

KDP also has this thing called Amazon Ads which is their advertising platform. You can run ads for your books directly on Amazon search results and product pages. I spend probably $500-1000 monthly on ads across my catalog and it’s been worth it for me but there’s definitely a learning curve. You can target keywords or other authors’ books or products, set your daily budget, and Amazon charges you per click. Some clicks convert to sales, most don’t, but the data helps you understand what readers are actually searching for.

The tax stuff gets complicated if you’re making decent money. Amazon sends out 1099s if you earn over $600 in a year and you’re responsible for quarterly estimated taxes if you’re in the US. I set aside about 30% of royalties for taxes which sounds like a lot but it’s better than getting hit with a massive bill in April. My cat just knocked over my coffee but anyway yeah taxes are annoying but necessary.

International rights are automatically handled – when you publish you select which territories you want to sell in and Amazon distributes accordingly. You can exclude specific countries if you want but there’s no real reason to unless you’ve sold rights to a traditional publisher in that region. I just check all the boxes and let it go worldwide.

Print quality complaints happen occasionally and Amazon’s customer service handles returns but it doesn’t affect you financially. If someone gets a damaged book Amazon eats the cost and ships them a new one. Your royalty already happened when the book sold so you don’t lose money on returns or damages. The system is honestly pretty author-friendly in that regard.

The community around KDP is huge – there are Facebook groups, Reddit threads, YouTube channels, podcasts, all dedicated to self-publishing on Amazon. I’ve learned more from other authors sharing what works than from any official Amazon documentation. Some people are super secretive about their strategies but most are pretty open about what’s working for them.

KDP isn’t perfect – the algorithms change, competition is fierce, Amazon makes decisions that don’t always make sense for authors. But as a zero-barrier-to-entry publishing platform that gives you access to millions of potential readers and handles all the logistics? It’s pretty incredible. I’ve made anywhere from $5k to $30k per year depending on how many books I publish and how much I focus on marketing, and that’s life-changing money for what started as a side hustle.

You’re gonna make mistakes with your first book, everyone does. Wrong categories, bad keywords, pricing too high or too low, cover that doesn’t quite fit the genre. That’s fine, you can fix all of it and you’ll learn what works for your specific niche and audience. Just get something published and start learning from real data instead of overthinking it forever.
