The distribution decision every self-publisher faces comes down to a fundamental question: do you give Amazon exclusivity in exchange for access to Kindle Unlimited, or do you go "wide" and sell through every retailer that will carry your book?

Neither answer is universally correct. The right choice depends on your genre, your reader demographics, how many books you have in your catalog, and your long-term publishing strategy. Here's how to think through it clearly.

KDP Select: The Exclusivity Deal

KDP Select is Amazon's exclusivity program for ebooks. When you enroll a title in KDP Select, you agree not to sell or distribute that ebook anywhere else for 90-day periods. In exchange, Amazon gives you:

  • Kindle Unlimited availability: Your book appears in the KU subscription catalog, and you earn per page read from the KU royalty pool
  • Kindle Countdown Deals: Time-limited price promotions that maintain your 70% royalty rate
  • Free Book Promotions: Up to 5 days per 90-day period where your book is offered free on Amazon
  • Potential for improved Amazon algorithmic visibility (not guaranteed, but observed by many authors in KU-heavy genres)

The KU income question

Kindle Unlimited income can be substantial — or negligible — depending entirely on your genre. The KU subscriber base skews heavily toward certain reading habits and genres. Categories where KU income regularly equals or exceeds direct purchase income:

  • Romance (especially contemporary, dark romance, and steamy subgenres)
  • Fantasy and science fiction with rapid-release schedules
  • Thrillers and crime fiction
  • Cozy mysteries

For authors in these genres with multiple books in a series, KU page reads can represent 50–80% of total income. Giving up KU to go wide can mean a significant income drop, at least initially.

KU per-page-read math: Amazon pays from a monthly pool, divided by total pages read across all KU titles. The rate fluctuates but has generally run around $0.004–$0.005 per page. A 300-page book fully read earns approximately $1.20–$1.50 per read — roughly the same as a $2.99 ebook sale at 70% royalty. If KU readers read your book more often than they'd buy it outright, KU is a net positive.

The cost of exclusivity

Exclusivity means giving up every non-Amazon channel. For most KDP Select authors, this means no Apple Books, no Kobo, no Barnes & Noble Nook, no library ebook programs through OverDrive or Libby, no direct sales from your website. In genres where the audience heavily uses these platforms, exclusivity is genuinely costly. In genres where 90%+ of readers buy on Amazon anyway, the cost is smaller.

The enrollment is also 90 days, auto-renewing. Each period can be opted out of, but you must actively do so — the default is to stay enrolled. When you decide to go wide, you'll need to wait until your current 90-day period expires before publishing elsewhere.

Going Wide: The Case for Every Retailer

Going wide means making your ebook available on every major platform. The main channels:

Direct retailer accounts

  • Amazon KDP (for Amazon, obviously — available to non-Select authors too)
  • Apple Books for Authors (direct upload, 70% royalty, strong in Apple ecosystem countries)
  • Kobo Writing Life (direct upload, important in Canada, UK, and international markets)
  • Barnes & Noble Press (direct upload, B&N Nook readership)

Aggregators

Managing uploads across six or more retail platforms individually is tedious. Most wide authors use an aggregator — a service that distributes to multiple platforms from one upload:

  • Draft2Digital: The most popular aggregator for indie authors. Distributes to Apple Books, Kobo, Barnes & Noble, Scribd, OverDrive, Bibliotheca, and others. Clean interface, good reporting, pays 90% of what retailers pay them. Many authors upload directly to Amazon and Apple while using D2D for everything else.
  • PublishDrive: Broader global distribution including Google Play Books and some international retailers that D2D doesn't reach. Subscription pricing model rather than per-sale percentage. Useful for authors with large catalogs where a flat fee makes more financial sense than a percentage.
  • IngramSpark: Also distributes ebooks wide, alongside print distribution. The Ingram connection means library access through OverDrive is particularly strong. Worth considering if you're already using IngramSpark for print.

Which genres benefit from going wide?

Wide distribution outperforms or matches KDP Select in specific contexts:

  • Cozy mystery backlist: Cozy readers are often older, Apple-loyal, and library-active — markets where wide performs well
  • Non-fiction: Non-fiction readers buy across platforms; KU is less dominant here
  • Romance backlist (not frontlist): Older titles that have exhausted their KU visibility can earn consistently on wide platforms indefinitely
  • International audiences: Kobo is dominant in Canada; Apple Books has strong penetration in Germany, Australia, and Japan; Google Play is important in emerging markets
  • Authors building a reader-owned business: Wide distribution means you're not dependent on Amazon policy changes

Direct Sales: The Highest-Margin Channel

Selling directly from your own website means you keep approximately 90–97% of the sale price (depending on the payment processor and delivery platform). This is categorically better royalty economics than any retailer. The platforms that make this possible:

  • Payhip: Free to start (5% transaction fee), reduces to 2% on a paid plan. Handles ebook delivery, discount codes, and affiliate programs. Simple setup, good for authors just starting direct sales.
  • Gumroad: Similar to Payhip — simple storefront with digital file delivery. Widely used by indie creators. Transaction fee of 10% on the free plan, dropping on paid plans.
  • Your own website with Shopify or WooCommerce: Full control, no transaction fees beyond payment processing (2–3%). Requires more setup and maintenance but gives you the cleanest customer relationship and data ownership.
  • BookFunnel: Primarily used for delivering ebooks to readers (via a reader-friendly app), often combined with a Shopify or Payhip storefront for the purchase itself.

The limitation of direct sales: discovery. Retailers bring customers to your book. Your website only reaches people who already know about you. Direct sales work best for authors with an email list, strong social media, or who do events — channels that drive people to their site intentionally.

The Hybrid Approach: Ebook Exclusive, Print Wide

Many experienced authors run a hybrid approach that separates the ebook and print decisions:

  • Ebook in KDP Select for KU income and Amazon visibility tools
  • Print book through both KDP Print and IngramSpark for combined Amazon fulfillment and wide bookstore/library distribution

This works because KDP Select's exclusivity clause applies only to ebooks. Print books can be distributed anywhere regardless of your ebook's enrollment status. The hybrid approach captures KU income on ebooks while maintaining the wide print distribution that opens bookstores and libraries.

How Long to Test Each Strategy

One of the most common mistakes in distribution strategy is making a decision based on insufficient data. Here's a reasonable testing framework:

  • New to KDP Select: Commit to three 90-day periods (nine months) before evaluating. One period isn't enough to build KU readership and momentum.
  • Moving from KDP Select to wide: Expect a dip in income during the first 3–6 months as you build visibility on new platforms. Non-Amazon readers don't know you yet — it takes time. Give wide at least six months before concluding it doesn't work.
  • Starting wide from the beginning: The most patient approach. You won't have KU income, but you'll build a diversified reader base from the start. Particularly appropriate for non-fiction and authors building a long-term brand.

The distribution question is ultimately a business strategy question. The best strategy for your book depends on understanding your readers, your genre, and how your income model works. What doesn't vary: the quality of your manuscript matters more than any of these choices. A great book finds readers across every distribution channel; an under-edited book underperforms on all of them.
