There is no single best ebook distribution platform. The right one depends on three things: how many books you’re publishing, whether your genre rewards exclusivity, and how much royalty you’re willing to trade for reach. Amazon KDP still sells the most copies for most authors, but almost every guide comparing platforms skips the number that actually decides the question: what a Kindle Unlimited page read is worth to you compared to a flat 60 percent royalty on a wide aggregator. This guide walks through that math, platform by platform, before you commit to one.
What Is an Ebook Distribution Platform?
An ebook distribution platform is the service that takes your finished manuscript and lists it for sale on retailers like Amazon, Apple Books, and Google Play, typically handling file conversion and metadata submission so you don’t upload to each store separately. The distinction most guides blur is between a distributor and a storefront. Amazon KDP is both at once, since it distributes to and sells directly on Amazon. Draft2Digital and Smashwords are distributors only. They have no storefront of their own; they push your file to other people’s stores and take a cut for the plumbing.
That difference matters more than it sounds. If you go with a pure distributor, your royalty terms are set by the retailer at the other end, not by the distributor you uploaded through. A pure storefront-distributor like KDP sets its own royalty split directly.
Ebook Distribution Platforms at a Glance
| Platform | Best For | Royalty Range | Format Preferred | Exclusivity Required |
|---|---|---|---|---|
| Amazon KDP | Maximum US reach, single-platform authors | 35% to 70% | Kindle format (auto-converted from EPUB or DOCX) | Only if enrolled in KDP Select |
| Apple Books | Apple-heavy readerships, higher royalties | Up to 70% | EPUB | No |
| Google Play Books | Android and emerging markets (Asia, South America) | Varies by region | EPUB | No |
| Kobo Writing Life | Canada, Japan, niche and genre-specific readers | Up to 70% | EPUB | No |
| Draft2Digital | Wide distribution without managing multiple dashboards | Retailer’s rate, minus a distribution cut | Converts automatically | No |
| Smashwords | Indie and niche genre discovery | Retailer’s rate, minus a distribution cut | EPUB, converts automatically | No |
| IngramSpark | Library and international/academic markets | Retailer’s rate, minus setup fees | EPUB | No |
Key Factors to Consider When Choosing a Distribution Platform
Four things decide which platform actually pays off for your book: where your readers already are, which file format each retailer demands, what marketing tools come built in, and how the royalty math changes at your specific price point. Get any one of these wrong and you either miss your audience or leave money on the table.
- Global Reach and Channels: Amazon Kindle Direct Publishing reaches over 300 million US customers on its own. Kobo Writing Life is the stronger pick if your readers are in Canada, Japan, or parts of Europe, especially for niche and genre-specific books.
- Format Compatibility: EPUB is the format nearly every platform accepts. Amazon converts EPUB and DOCX files into its own Kindle format automatically, so you rarely need to convert manually yourself; aggregators like Draft2Digital handle the conversion for every retailer from a single upload.
- Marketing and Promotional Tools: KDP Select gives you Kindle Countdown Deals and Kindle Unlimited page reads, while Apple Books can feature your title to its device-owning audience directly.
- Royalties and Pricing: Amazon KDP pays between 35% and 70%, depending on your book’s price and the country of sale. A $4.99 ebook priced within the 70% band nets you roughly $3.49 per sale before Amazon’s delivery fee; the same book priced outside that band, or sold in a territory Amazon treats differently, drops to 35%. Check your specific price and territory before assuming you’re getting the higher rate.
Brief Overview of Major Ebook Distribution Platforms
Amazon Kindle Direct Publishing (KDP)
Amazon KDP is where most authors should start, because it reaches close to 80% of all US ebook sales through a single dashboard. KDP Select adds Kindle Unlimited page reads and Kindle Countdown Deals, but enrolling means your ebook can’t be sold anywhere else during that term. That trade-off is the entire decision: KDP Select rewards a backlist author who already has readers inside Kindle Unlimited, and costs a debut author every reader who shops elsewhere. KDP also supports specialized formats like graphic novels through Kindle Comic Creator. Every KDP title gets its own ASIN instead of an ISBN, which is why Kindle-exclusive authors often skip buying an ISBN altogether.
Apple Books
Apple Books puts your book in front of more than 100 million Apple device users and pays competitive royalties without requiring exclusivity. The catch is real: publishing directly requires a Mac, so Windows-only authors typically go through an aggregator instead of Apple’s own dashboard.
Google Play Books
Google Play Books’ advantage is reach into Android-dominant markets, particularly across Asia and South America, where ebook consumption is growing faster than in the US or UK. If your genre or audience skews toward those regions, this platform earns you visibility that Amazon and Apple simply don’t have there.
Kobo Writing Life
Kobo is the platform indie authors lean on when they want a loyal, genre-specific reader base rather than the biggest possible audience. Its strongest markets are Canada, Japan, and parts of Europe, which makes it a smart complement to KDP rather than a replacement for it.
Nook Press (Barnes & Noble)
Nook Press still matters if your core readers are in the US and you want the option of in-store promotion through Barnes & Noble. It’s no longer the dominant retailer it once was, but it remains a low-effort addition once your book is already formatted for wide distribution.
Best Ebook Aggregators for Broad Distribution
Aggregators exist for authors who want their ebook everywhere without logging into five separate dashboards. Draft2Digital, Smashwords, and IngramSpark each take one upload and push it to multiple retailers, converting your file to whatever format each one requires along the way. Draft2Digital and Smashwords charge no upfront fee and instead take a percentage of what the retailer pays you; IngramSpark charges a one-time setup fee per format but reaches libraries and international print-adjacent markets the other two don’t touch. The trade-off for that convenience is that you don’t control the retailer relationship directly, which matters if a specific retailer ever needs a support ticket resolved fast.
E-Reading Subscription Services
E-reading subscription services put your book in front of readers who browse a library instead of buying titles one at a time, the way Netflix works for streaming instead of DVD purchases. KoboPlus, Scribd, Storytel, Bookmate, Dreame, 24symbols, and Perlego all pay authors through a share of reading minutes or a per-borrow fee rather than a flat sale price. For a backlist title that has already earned out on retail, subscription inclusion is close to pure incremental income, since it’s reaching readers who wouldn’t have bought the book outright.
Choosing Platforms Based on Your Goals
Match the platform to what you’re actually optimizing for, not to what other authors are using:
- Broad reach across every retailer: An aggregator like Draft2Digital or IngramSpark gets your book into the most stores with the least manual work.
- A loyal reader base on one platform: Amazon KDP or Apple Books, since both let repeat readers find your next release without you doing anything extra.
- A specific niche market: Kobo Writing Life, particularly for genre fiction with a dedicated readership outside the US.
Exclusive vs. Wide Distribution: Which Actually Pays More
Catalog size and genre decide whether exclusivity or wide distribution earns more, far more than personal preference does. A single debut novel usually earns more going wide, because it needs every possible reader to find it and can’t yet rely on repeat traffic from one platform’s recommendation engine. A backlist of five or more books in the same genre often earns more inside KDP Select, because Kindle Unlimited page reads compound across a catalog in a way a single title can’t replicate. Run the math on your specific catalog before assuming either answer is universal. Many authors land on a hybrid model instead, keeping one series exclusive in KDP Select while distributing another wide.
Ebook Formatting and Conversion
Ebook formatting prepares your file’s layout for the device it will be read on, and getting it wrong is the most common reason self-published ebooks get returned. EPUB is the format nearly every retailer accepts except Amazon, which converts EPUB or DOCX files into its own Kindle format automatically on upload. Most formatting problems (broken internal links, inconsistent fonts, images that don’t scale on smaller screens) come from formatting a manuscript in Word and uploading it as-is instead of running it through a proper EPUB converter first. Aggregators like Draft2Digital handle this conversion for you across every retailer from one file.
Other Tips for Selecting the Right Platform
- Know where your specific readers already are. Genre, age group, and region change which platform performs best, more than any platform’s overall market share does.
- Weigh the platform-specific perks against the lock-in. Kindle Countdown Deals and Apple’s in-app promotion only help if you’re comfortable with the exclusivity or platform-lock each one requires.
- Prioritize ease of use if this is your first ebook. A platform like Spines pairs an intuitive dashboard with support through the entire process, which matters more on book one than it will on book five.

FAQ: Best eBook Distribution
Q: What is the best platform to sell ebooks on?
Amazon KDP is the best overall platform to sell ebooks on for most authors, since it reaches roughly four out of five US ebook sales through one dashboard. That said, the best ebook distribution platform depends on your genre and catalog size. A niche fiction backlist often earns more through Kobo Writing Life or a wide aggregator than through KDP alone.
Q: Which ebook platform has the best reader base?
Amazon KDP has the largest overall reader base in the US, reaching close to 80% of ebook sales, but “best” depends on genre. Kobo Writing Life has a more loyal, engaged reader base for niche genre fiction outside the US, and that engagement often converts to more reviews and repeat readers than KDP’s larger but more diffuse audience.
Q: Is selling ebooks still profitable?
Yes, selling ebooks is still profitable, though margins are thinner than they were during the early Kindle boom. Debut authors typically break even within their first year if they price competitively and distribute wide, while backlist authors in genre fiction often earn steady monthly income through Kindle Unlimited page reads. Profitability now depends more on catalog size and consistent output than on any single platform.
Q: How much does an author make on a $20 book?
On a $20 ebook, Amazon KDP actually pays a 35% royalty, not 70%, because the higher rate only applies to books priced between $2.99 and $9.99. That means a $20 ebook nets about $7 per sale on KDP, less than a $9.99 book earning 70% would pay. Apple Books and Kobo do not cap their higher royalty by price, which makes them worth comparing directly for higher priced nonfiction or box sets.
Q: Should I distribute my ebook exclusively or go wide?
Go wide if this is your first book or you write across genres. Go exclusive with KDP Select if you have a backlist in one genre, since Kindle Unlimited page reads compound across multiple titles in a way a single book cannot replicate. There is no universal right answer, only a right answer for your specific catalog.
Q: What’s the difference between an ebook distributor and an ebook aggregator?
They are the same thing in practice. An aggregator such as Draft2Digital, Smashwords, or IngramSpark distributes your file to multiple retailers from one upload, while a platform like Amazon KDP is both the distributor and the retailer at once. The distinction matters because aggregators do not set your royalty rate; the retailer at the other end does.
Q: What’s the best platform for reaching readers outside the US?
Kobo Writing Life leads for Canada, Japan, and parts of Europe, while Google Play Books reaches Android heavy markets across Asia and South America better than Amazon or Apple do. Choose based on where your specific genre already has readers, not overall platform size.
Q: Which type of ebook sells most?
Genre fiction, especially romance, fantasy, and mystery, consistently outsells other ebook categories because those readers buy and finish books faster, then read through an author’s backlist once they find someone they like. That reading pattern is exactly why Kindle Unlimited and Kobo Plus reward genre fiction authors specifically: those platforms pay per page read, and fast, repeat readers generate more page reads than slower nonfiction readers do.
