An ebook’s success hinges on an effective distribution strategy that connects it with readers. The placement of the digital file determines the book’s visibility, profit margin, and the author’s control over the sales process. Self-published authors generally choose between leveraging established retail channels with built-in audiences or pursuing direct sales for higher returns and customer relationship management. Understanding the structure and requirements of each option is necessary to select the most suitable approach for a long-term publishing career.
The Dominant Channel: Selling on Amazon KDP
Kindle Direct Publishing (KDP) is the self-publishing platform for the world’s largest ebook retailer, making it an almost unavoidable component of any distribution plan. Authors must first decide whether to enroll their ebook in KDP Select, which requires 90 days of digital exclusivity on the Amazon platform in exchange for promotional advantages. The primary benefit of KDP Select is automatic inclusion in Kindle Unlimited (KU), a subscription service where authors earn royalties based on pages read. This can provide a substantial revenue stream in genres popular with binge-readers. KDP Select also grants access to exclusive promotional tools like Kindle Countdown Deals and Free Book Promotions, which help boost a book’s visibility within the Amazon ecosystem.
The exclusivity requirement means the digital version cannot be sold or offered for free anywhere else during the 90-day enrollment period. Authors who choose not to enroll in KDP Select are free to distribute their ebook on all other platforms, a strategy known as “going wide.” KDP offers two royalty rate options: 70% and 35%.
To qualify for the 70% rate, the ebook’s list price must fall between \$2.99 and \$9.99, and the file size must be below a certain limit, as a delivery fee is deducted. The 35% royalty option applies to books priced outside that window or for sales in ineligible territories. Choosing KDP Select leverages Amazon’s massive market share, but confines the author to a single platform. Opting out trades immediate promotional access for the freedom to build a diverse revenue portfolio across multiple retailers.
Going Wide: Reaching All Major Global Retailers
Distributing an ebook widely involves making it available on major retail platforms outside of Amazon, reaching readers who use devices like Apple iPads, Kobo e-readers, and Barnes & Noble Nook devices. Key global retailers include Apple Books, Kobo Writing Life, Barnes & Noble Press, and Google Play Books. This strategy is effective for reaching international markets where Amazon’s market share is not dominant.
Authors pursuing a wide strategy use two primary methods: direct upload or an aggregator service. Uploading directly to each retailer’s platform provides the highest possible royalty rate, often 70% of the list price, since no middleman takes a cut. The trade-off for this higher royalty and greater control is increased administrative complexity, requiring the author to manage separate accounts, upload files individually, and track sales data across numerous dashboards.
Alternatively, authors can use distribution aggregators like Draft2Digital or Smashwords to streamline the process. The author uploads files and metadata once, and the service distributes the ebook to a large network of global retailers and libraries. Aggregators typically take around 10% of the final royalty for this convenience. They consolidate sales reports and payments into a single dashboard, significantly reducing the administrative burden.
Selling Ebooks Directly to Your Audience
Selling an ebook directly from an author’s own website or owned channels offers the maximum control and profit margin. This approach eliminates the retailer’s commission, allowing the author to retain up to 90% or more of the sale price after accounting for payment processing fees. The most significant advantage is the acquisition of direct customer data, including the buyer’s email address, which retailers generally withhold. This data is invaluable for building a proprietary email list, the most effective tool for long-term marketing and announcing new releases.
Direct sales require the author to provide both an e-commerce solution for payment and a secure delivery mechanism for the digital file. Platforms like Gumroad, SendOwl, and Payhip are specialized tools that handle payment processing and automatic, secure delivery of the ebook file to the customer. These platforms can be integrated into an existing website built on a service like WordPress with WooCommerce or a Shopify store. This model shifts the responsibility for sales and delivery onto the author, but the trade-off is a stronger, more profitable relationship with the reader.
Leveraging Niche and Subscription Platforms
Authors can explore alternative platforms that cater to specialized audiences or offer subscription-based revenue models. Niche-specific distribution is relevant for non-fiction or technical works, which can be placed on specialized industry platforms focused on academic or professional subjects. These sites target a pre-qualified audience seeking specific information, often leading to higher perceived value and premium pricing potential.
Another model involves distributing content through subscription or patronage platforms like Patreon or Substack. Authors use these services to serialize their work, releasing new chapters or sections regularly to paid subscribers. Patreon allows authors to create tiered membership levels, offering exclusive content or early access to the ebook as a member benefit. Substack is used by authors to build an audience and then sell the compiled ebook as a one-time purchase or a bonus for a paid subscription. This approach leverages direct audience engagement, turning a loyal reader base into a consistent monthly revenue source.
Essential Preparation Before Uploading
Successful ebook publishing relies on meticulous preparation of the digital file and its associated data, regardless of the chosen distribution channel. The most significant technical hurdle is ensuring the ebook is formatted correctly, primarily in the EPUB 3 format, the industry standard for reflowable text across most retailers. Amazon KDP primarily uses the MOBI or KF8 format, though it accepts EPUB and DOCX files for conversion. Authors should avoid uploading PDF files, as they do not reflow properly on different screen sizes, leading to a poor reader experience.
A professional-quality, high-resolution cover design is mandatory, as it is the primary marketing tool on digital storefronts. Beyond the file itself, optimizing metadata is crucial for discoverability, as this information tells retailers and search engines what the book is about. Metadata includes the title, author name, keywords, and categories. Authors should research and select specific categories and embed relevant keywords into the descriptive copy, especially in the first 50 to 100 words, to maximize the book’s search ranking on retailer sites. Finally, the initial pricing strategy must align with the chosen distribution path, such as ensuring the price falls within the \$2.99–\$9.99 range to secure the 70% royalty on Amazon.
