Compound the Catalog

Going Wide and Into International Markets, the Right Way

Apple, Kobo, Google, and Nook each have their own math — and German and Spanish are the highest-ROI translation gaps. How to expand without cycling.

Amazon's share of indie author top-revenue designations fell three points in two years — from 91 percent in 2023 to 87 percent in 2024 and 83 percent in 2025, per Written Word Media's annual survey of 1,346 indie authors. That is not a signal to abandon Amazon; it is a signal that the rest of the market is growing faster. Authors who distribute across multiple channels report 34 percent higher average monthly income than Amazon-exclusives — a gap that compounds across every backlist title already written. But wide is not the same as distributing files everywhere and hoping. Each non-Amazon store carries its own promotional infrastructure, its own royalty math, and its own patience requirement. Getting the mechanics right before you expand is the difference between a compounding wide catalog and an experiment abandoned at 60 days.

The rule that breaks most wide attempts: never evaluate non-Amazon platforms at 30 to 60 days against your old Kindle Unlimited page-read numbers. Apple, Kobo, and Google build their algorithms and editorial relationships on a 6-to-12-month clock. Pulling books back into KDP Select resets that clock to zero every time — and each reset is momentum you cannot recover on demand. The only correct cadence is a 90-day arithmetic review: actual page-read income against projected wide sales. Never emotion; never a slow first month.

Why Is Amazon's Market Share Declining — and What Does That Create for Wide Authors?

Subscription reading now accounts for 56.43 percent of global ebook revenue — a category that spans Kindle Unlimited but also Kobo Plus, which operates across 23-plus countries on a fully non-exclusive model, and Apple Books' growing bundle reach. The global ebook market sits at an estimated $14.6 to $14.9 billion in 2025 by most measures, with Asia-Pacific growing at 9.2 percent CAGR and Brazil's ebook market up 67 percent in 2024. Non-Amazon subscription platforms are specifically expanding into territories where Amazon has less presence: Kobo Plus now operates in Spain (launched July 2024), and Apple Books distributes to 51 country storefronts. The market outside the US Amazon storefront is not a rounding error; it is where the growth is concentrating.

For a backlist-heavy catalog, wide distribution is specifically a compounding play: every title already written becomes eligible for Kobo promotions, Apple editorial pitches, and international keyword indexing the moment it exits KDP Select. A single series with five books carries five times the promotional surface area of a standalone — and that surface expands with every store added.

How Does Each Wide Platform's Promotional Infrastructure Actually Work?

Distribution alone is not the tactic. Each platform has a promotional mechanism that rewards active management, and each requires a specific first action that most authors never take.

PlatformRoyalty rateKey promotional leverFirst required action
Kobo Writing Life70% at $2.99+, no upper cap; 45% belowPromotions Tab: Price Drops, Buy More Save More, Daily Deals (weekly refresh)Email writinglife@kobo.com to unlock — off by default on all accounts

Barnes & Noble Press70% flat at all price points; 30-day paymentLess-crowded US market; metadata and cover carry more relative weightDistribute via Draft2Digital unless B&N is a specific priority

Kobo: The Promotions Tab Loop

Kobo Writing Life pays 70 percent on titles priced at $2.99 and above, with no upper price cap — meaning a $19.99 box set earns 70 percent rather than Amazon's 35 percent above $9.99. Kobo Writing Life's official royalty documentation confirms the ceiling-free structure. Joanna Penn keeps her fiction box sets off Amazon and prices them on Kobo and Apple Books precisely to exploit this royalty arbitrage on high-value bundles.

The Promotions Tab is inactive by default and requires one email to writinglife@kobo.com to unlock. Once enabled, available promotions refresh weekly — check every seven days. Types include Price Drop Sales (geo-specific or seasonal), Buy More Save More bundles (Buy 2 Get 1 Free, three for $5, Buy 1 Get 1 Half-Price), Promo Code Sales (no price-matching risk), and Daily Deals that require a 50 percent discount but feature on the Kobo homepage and in email campaigns. The cost model is author-friendly: most promotions charge a 10 percent additional royalty reduction during the sale window only; if a title does not sell, the author pays nothing.

Kobo's geographic profile matters for setting expectations. Canada accounts for 51 percent of all indie Kobo sales; France is the largest non-English market. Fifty percent of Kobo readers are 55 or older and 30 percent are retired — a quality-oriented demographic, not bargain-hunters. Mark Lefebvre's guide on Jane Friedman's site documents the demographic in detail, noting that Indian pricing must be set substantially below US equivalents. Meaningful traction takes 6 to 9 months. Enroll in Kobo Plus across all territories and leave it there.

Apple Books: The Preorder Stack and the 250 Codes

Apple Books pays 70 percent at every price point and does not price-match competitors — a meaningful structural advantage for premium-priced nonfiction or high-value box sets. Featured placement is entirely editorial; Apple accepts no advertising or co-op fees for storefront visibility, per Apple Books for Authors' launch planning guide.

Two Apple mechanics reward active use. First, preorders count on purchase day and again on launch day — a double sales spike that Amazon does not replicate. A community-observed benchmark (not officially documented by Apple): accumulating roughly 500 preorders triggers chart movement and attracts Apple's merchandising team's attention. Set preorders up to 12 months in advance; description and publication date can be updated anytime. Second, every publisher receives 250 free promo download codes per title at file approval. Distributing these immediately to ARC readers seeds ratings before launch day, feeding the Apple algorithm before the book competes for organic placement. Submit an editorial feature request at least two weeks before release with a detailed marketing plan.

Apple also permits affiliate links inside paid advertising — unlike Amazon's affiliate terms — and offers a 7 percent affiliate commission on top of the 70 percent royalty. Reedsy's 2026 Apple Books publishing guide documents the affiliate mechanism: submit an Apple affiliate URL to BookBub and the system auto-targets Apple buyers in your campaigns at no extra cost.

Google Play: Accept the 2019 TOS Before Anything Else

Google Play Books pays 70 percent of list price in more than 60 countries — but only for publisher accounts that accepted Google's 2019 updated terms of service. Legacy accounts that have not accepted are permanently locked at 52 percent, and past sales cannot be retroactively corrected, per Google Play Books' official Revenue Split FAQ. Accepting the TOS is a single checkbox on signup with no meaningful downside and an immediate 18-percentage-point royalty improvement across 60-plus eligible markets.

Google operates a wholesale model: the retailer sets the final consumer price and may discount without notice. Counter-strategy: set your Google Play list price $1.00 to $2.00 higher than on other stores. Google pays royalties on the list price even when the retail price is auto-discounted, so the buffer protects per-sale earnings. Write book descriptions with primary searchable keywords in the first 150 characters — Google Play descriptions are indexed by the broader Google web search engine, adding a discovery layer entirely outside the bookstore. Google Play reaches 3-plus billion active Android devices globally, with particular strength in India, Brazil, Indonesia, Southeast Asia, and Africa — markets where Amazon has substantially less reach.

Which Aggregator Should You Use for the Long Tail?

The practical architecture for most catalogs: direct accounts on Kobo, Apple Books, and Google Play; one aggregator for everything else. Never distribute to Amazon through any aggregator — go direct on KDP to access Countdown Deals, Free Days, and KDP Select. Never distribute to Google Play through an aggregator if a direct Publisher account is available; the aggregator layer costs you price-scheduling control and granular promotional access.

Draft2Digital charges 10 percent of net royalties with no upfront fee and distributes to 17-plus retailers including Tolino (Germany), Vivlio (France), OverDrive, Bibliotheca, and Hoopla (libraries), and the Smashwords storefront. Scribecount's D2D guide outlines the full distribution network. D2D's Promotions Team maintains direct relationships with merchandising managers at Apple Books, Kobo, Hoopla, and OverDrive — and in 2024 placed 5,835 books in partner promotional events from 13,462 author entries across 57 promotional invitations from retail and library partners. Fill out the D2D Promotions Form with bestseller history, rating averages above 4.5 stars, and award wins; resubmit after each new achievement. Enroll all eligible backlist in Smashwords' three annual sitewide sales: Read an Ebook Week (March), Summer/Winter Sale (July, roughly 100,000 participating ebooks in 2025), and the End of Year Sale (December through January, 228,000-plus ebooks in 2024).

PublishDrive runs a subscription model with zero royalty commission — you keep 100 percent of net retailer royalties minus a monthly fee ranging from $13.99 to $83.99 per year depending on catalog size. Its decisive advantage is China: PublishDrive distributes to DangDang, JD, and CNPeReading, reaching 670 million digital readers in a market that grew 16.6 percent year-over-year in 2025, per PublishDrive's China market guide — a channel no other major English-language aggregator provides. One critical risk: if a PublishDrive subscription lapses, all 400-plus storefronts simultaneously unpublish your titles. Best suited for high-volume authors where the subscription fee is a small fraction of retained royalties.

StreetLib is the European specialist. Its Pro plan retains 85 percent of net revenues and distributes to FNAC (France, Spain, Belgium), Casa del Libro (Spain and Latin America), La Feltrinelli and IBS (Italy), Tolino (Germany), and BorrowBox (UK, Ireland, Australia, and New Zealand — added as a 2025 partnership), per StreetLib's 2025 Year in Review. StreetLib is the complement to D2D for authors who want maximum European retail coverage. Note that the EU's European Accessibility Act (2025) now makes accessible EPUB a legal requirement for European distribution, not an optional enhancement.

Why Should German and Spanish Be Your First International Targets?

Amazon's Kindle Translate launched its first two language pairs as English to and from Spanish and German to English. That sequencing is a market signal: these are where the catalog gaps are widest and where English-language genre fiction demand is already established, per Amazon's Kindle Translate launch announcement. Fewer than 5 percent of Amazon's catalog exists in more than one language — meaning the competitive density in German and Spanish is still a fraction of what English-language authors face domestically.

Germany's ebook market is structurally distinct from any other. Thalia — the anchor chain for the Tolino platform — reported 18 percent ebook revenue growth and 21 percent audiobook revenue growth in fiscal year 2024/25, per Literary Queens' Tolino analysis. Tolino holds 40 to 44 percent of the German ebook market — a share entirely invisible to any KDP Select-enrolled title. Publishing on Amazon.de alone reaches roughly 60 percent of German ebook buyers. Access Tolino via Draft2Digital, PublishDrive, or StreetLib; it is non-exclusive, so there is no KU-style penalty. Germany also operates the Buchpreisbindungsgesetz — a fixed-price book law requiring uniform pricing across all retailers. You cannot run a sale on Kobo.de while holding full price on Amazon.de; the German price must move together across all channels simultaneously, per Jane Friedman's German market guide. For German marketing, XTME (described as the strongest platform for indie novel advertising in Germany) and LovelyBooks (Germany's Goodreads equivalent) are the two primary channels to establish before or at launch.

Spanish-language ebook revenue grew 10.4 percent in 2024, with Mexico leading at plus 12 percent, per Bookwire's Spanish Market Report. NielsenIQ data shows Spanish fiction ebook revenue up 12.0 percent in 2024, with fiction accounting for three-quarters of total Spanish ebook turnover. The Spanish audiobook market grew 45.7 percent in 2023 — a companion opportunity once the ebook edition is established. Spanish is the primary language of 21-plus countries with distinct market dynamics. Do not grant worldwide Spanish translation rights in a single license; license territory-by-territory and insist on reversion clauses tied to minimum annual sales thresholds.

How Do You Price Across International Markets Without Leaving Money Behind?

Automatic currency conversion on any platform produces irrational-looking prices — $5.06 CAD, €4.37 — and may accidentally drop below royalty-tier thresholds. Set every international price manually. Round to .99 in English-speaking markets; round to .49 or .99 in EUR and GBP markets. Per Book Launchers' international pricing guide, the correct structure is purchasing-power parity by tier:

  • Tier 1 — US, UK, Canada, Australia: full price or a slight premium over the US baseline. Australia typically runs 50 to 70 percent above US equivalents; Canada roughly 30 percent above. David Gaughran notes that Australian and Canadian readers are hungrier for deals than US audiences — meaning the same discount delivers higher click-through and conversion with less advertiser competition.
  • Tier 2 — Germany, France, and core EU: 10 to 20 percent below the US baseline. For Germany specifically, this price becomes the uniform legal price across all German retailers simultaneously under the Buchpreisbindungsgesetz — set it once and coordinate any future changes across every channel together.
  • Tier 3 — Brazil, India, Mexico: 50 to 70 percent below the US baseline. Localized pricing in Brazil and India increases user acquisition by more than 60 percent, per DataIntelo's ebook market research. These markets also require KDP Select enrollment to access Amazon's 70 percent royalty rate; wide authors accept the 35 percent KDP rate in those territories and compensate via Kobo's and Google Play's uncapped 70 percent on the same titles.

What Is the Most Cost-Efficient Path to a Translated Edition?

Professional human translation runs $7,000 to $17,500 per novel at 7 to 9 cents per word for German, per Writers & Artists' foreign rights guide. That capital requirement demands a proven readership to recover. The rule documented by the Alliance of Independent Authors is direct: do not invest in translation before domestic English traction exists. Translate your best-performing backlist title, not your newest release. Measure 90 days of page reads and unit sales; only then decide whether the data justifies additional investment.

Three pathways are available at different capital thresholds:

  1. AI-assisted hybrid (lowest capital): Use ScribeShadow ($49 per month for up to 50,000 words, 19-plus languages, approximately 70 percent first-pass accuracy per The Write Practice's independent German-speaker review), GlobeScribe ($100 per title per language, per Publishers Weekly's AI translation analysis), or Amazon's Kindle Translate (currently free beta, English to and from Spanish and German to English, completing translations within a few days and eligible for KDP Select enrollment — books carry a visible Kindle Translate label). Commission a native editor to fix idiom, tone, dialogue, and cultural references before publishing. This hybrid cuts cost 40 to 60 percent versus full human translation while preserving voice fidelity. AI output published without any native editorial review generates negative reviews that are effectively permanent in markets where you have no established author brand to offset them.
  2. Licensed rights deal (zero capital): Accept inbound offers from foreign publishers at the standard 10 percent royalty plus an advance — typically $5,000 or less, with competitive auction situations reaching $40,000-plus, per ALLi's ultimate translation guide. Foreign rights agent commission runs 20 percent. The zero-capital advantage is real: Clare Lydon accepted German and Brazilian publisher offers requiring no translation cost. Always retain ebook and audio rights separately — many foreign publishers propose contracts covering all formats, and signing away ebook and audio rights alongside print surrenders the highest-margin formats for years.
  3. Full human translation (highest quality ceiling): Source professional translators via Upwork or specialized agencies; vet past work before committing. David Penny (Thomas Berrington Historical Mysteries) used human translators for German, then ran Amazon Ads on Amazon.de and earned three times his advertising spend. Localize the entire product ecosystem — blurb, Amazon keywords, author page on the local storefront (Amazon.de, Amazon.es), and cover. A German-language manuscript with an English blurb converts at a fraction of a fully localized title's rate.

The sequence matters as much as the pathway. Do not attempt niche language markets — Finnish, Polish, Arabic — before German and Spanish. The tools, promotional infrastructure, and translator talent pool in those two markets are materially more mature. Start where the data is clearest, build a proof point, and expand from there on evidence rather than ambition.

Frequently asked

How long should I wait before deciding wide is not working?

The correct evaluation window is 90 days, not 30 to 60. Apple, Kobo, and Google build their algorithms and editorial relationships on a timeline of 6 to 12 months of consistent availability. Authors who go wide, judge results at 60 days against their old Kindle Unlimited page-read numbers, and pull books back into KDP Select restart that clock to zero every time. On Kobo specifically, consistent presence is required for 6 to 9 months before meaningful traction develops. Re-evaluate every 90 days by comparing actual page-read income against projected wide sales on the arithmetic — not the emotion of a slow month. Also note: the New York Times and USA Today bestseller lists require multi-retailer sales, meaning Amazon exclusivity makes those lists permanently unavailable.

What is the Kobo Promotions Tab and how do I unlock it?

The Kobo Writing Life Promotions Tab gives enrolled authors access to Kobo's curated promotional events — Price Drop Sales, Buy More Save More bundles (Buy 2 Get 1 Free, three for $5, Buy 1 Get 1 Half-Price), Promo Code Sales, and Daily Deals that appear on Kobo's homepage and in email campaigns. It is inactive by default on every new account; you must email writinglife@kobo.com once to request activation. Once unlocked, available promotions refresh weekly. Most charge an additional 10 percent royalty reduction during the active sale window only, with no cost to the author if the title does not sell. A Daily Deal requires a 50 percent or larger discount and is among the highest-visibility slots available to indie authors outside a BookBub Featured Deal.

Does Google Play pay the same 70% royalty as Kobo and Apple Books?

Not automatically. Google Play pays 70 percent of list price in more than 60 eligible countries — but only for publisher accounts that accepted Google's 2019 updated terms of service. Accounts that have not accepted are locked at 52 percent, and past sales cannot be retroactively corrected. Accepting the TOS is a single action on signup with no meaningful downside; it unlocks an immediate 18-percentage-point royalty improvement in eligible markets. A second complication: Google operates a wholesale pricing model and can discount the final consumer price without notice while still paying the author based on list price. The standard counter-strategy is to set your Google Play list price $1.00 to $2.00 higher than on other stores to offset Google's auto-discounting behavior.

Should I use Draft2Digital or PublishDrive as my wide aggregator?

The two serve different catalog profiles. Draft2Digital charges 10 percent of net royalties with no upfront fee, distributes to 17-plus retailers including Tolino and Vivlio, and provides access to three annual Smashwords sitewide sales — making it the lower-risk choice for authors with smaller catalogs or early in their wide transition. PublishDrive runs a subscription model from $13.99 to $83.99 per month, keeps 100 percent of net royalties after the fee, and is the only major English-language aggregator with Chinese storefront distribution via DangDang, JD, and CNPeReading. PublishDrive economics favor authors consistently earning hundreds of dollars monthly from wide sales. One PublishDrive risk with no D2D equivalent: if your subscription lapses, all 400-plus storefronts simultaneously unpublish your titles.

Is AI translation good enough to publish professionally?

AI translation tools — ScribeShadow, GlobeScribe, Amazon's Kindle Translate — produce usable first drafts, not publishable manuscripts. Independent reviewer testing of ScribeShadow found approximately 70 percent first-pass accuracy in German, meaning roughly 30 percent of the output needs substantive editing before it is ready for publication. The correct workflow is the AI-assisted hybrid: use an AI tool for the first draft, then commission a native-speaking editor or proofreader to fix idiom, tone, dialogue, and cultural subtext before uploading. This hybrid approach cuts total cost 40 to 60 percent versus full human translation while preserving voice fidelity. Publishing pure AI output without native editorial review accumulates negative reviews that are effectively permanent in markets where you have no established author brand.

Can I enroll in Kobo Plus and still sell on Apple Books and Google Play?

Yes. Kobo Plus is explicitly non-exclusive. Enrolling your titles in Kobo's subscription service does not require removing them from Apple Books, Google Play, Barnes and Noble, or any other retailer. You can enroll in Kobo Plus and maintain a fully wide distribution stack simultaneously. Kobo Plus pays per minute read — roughly 60 percent of the monthly subscriber revenue pool divided by total minutes read across all enrolled titles. A three-hour read yields approximately $0.29 at current sample rates; a six-hour read approximately $0.94. The payment threshold is $50 USD, paid 45 days after month-end. Enroll in all Kobo Plus territories rather than selecting specific countries — this automatically includes future expansion markets without additional action on your part.
