Going Wide vs KDP Select: Which Publishing Strategy Earns More?

A data-informed comparison of KDP Select exclusivity vs wide distribution for indie authors: what each strategy offers, who benefits from each, and how to decide which is right for your books.

The KDP Select vs. wide distribution decision is one of the most consequential choices an indie author makes for each book. KDP Select offers access to Kindle Unlimited, Amazon's subscription library, in exchange for 90-day exclusivity on Amazon. Going wide means distributing to Kobo, Apple Books, Barnes & Noble, and other platforms without any exclusivity restriction.

Neither is universally better. The right choice depends on your genre, your existing audience, your goals, and the current publishing landscape. This guide examines both strategies honestly, with the factors that tend to favor each.

What KDP Select is

KDP Select is Amazon's program for ebook exclusivity. When you enroll a book in KDP Select, you agree that the ebook version of that book will not be available on any other retail platform for 90 days (one enrollment period). You can renew at the end of each period.

Benefits of KDP Select enrollment:

Kindle Unlimited access: your book is available to KU subscribers to borrow without paying per book. You earn a per-page-read royalty from KDP's Global Fund, rather than a per-sale royalty.
Kindle Countdown Deals: you can run a time-limited price discount that still pays at the 70% royalty rate for the duration of the promotion.
Kindle Free promotions: you can make your book free for up to 5 days per 90-day enrollment period.
Amazon algorithm signals: some authors report that KDP Select enrollment improves a book's visibility within Amazon's recommendation engine, though Amazon doesn't confirm this officially.

What KDP Select requires:

Your ebook cannot be available on any platform other than Amazon during KDP Select enrollment. This means no Kobo, no Apple Books, no B&N, no Google Play Books, no Smashwords, no Draft2Digital distribution. Print books and audiobooks are not affected; only ebooks.

What going wide means

Going wide means distributing your ebook to all platforms where it can be sold. Typically:

Amazon KDP (for your Kindle ebook)
Kobo Writing Life or Draft2Digital to Kobo
Apple Books directly or through D2D
Barnes & Noble Press directly or through D2D
Draft2Digital for library distribution (OverDrive, Bibliotheca, Hoopla)
Google Play Books (through direct setup or aggregators)
Scribd (through aggregators)
Various international platforms

Going wide requires more account management but puts your book in front of readers who don't use Amazon.

Kindle Unlimited: the key KDP Select component

The primary benefit of KDP Select for most authors is Kindle Unlimited access. Understanding how KU pays is essential to evaluating whether KDP Select makes financial sense for your books.

How KU page reads work: when a KU subscriber reads your book, Amazon tracks each page read (KENP: Kindle Edition Normalized Pages). At the end of the month, Amazon calculates a per-page-read rate based on the total pages read across all KU books and the total size of the monthly Global Fund (which Amazon sets).

Recent per-page-read rates: the KENP rate has historically been in the range of $0.004 to $0.006 per page. A 350-KENP book (approximately 350 pages) read in full earns roughly $1.40 to $2.10 per complete read.

Comparing KU read to a sale: at $4.99 with 70% royalty, you earn $3.49 per sale. If the same reader in KU reads your 350-page book at $0.005/KENP, you earn $1.75. For KU to be more profitable than selling at $4.99, you need readers to read your book more than once (unlikely) or you need KU to dramatically increase the number of readers.

This math changes significantly when:

Your book is very long (a 700-KENP epic fantasy earns $3.50 from a full KU read at $0.005, comparable to a $4.99 sale)
KU readers read your book who would not have bought it at full price (KU expands your total readership)
Your books have high series read-through, where each book borrowed in KU generates page reads for multiple books

Which genres benefit most from KDP Select

KU penetration varies significantly by genre. In some categories, a large proportion of readers use KU; in others, KU readers are a small fraction of the audience.

KDP Select tends to perform better for:

Kindle Unlimited-heavy genres: fantasy (particularly epic and LitRPG), romance (certain romance subgenres like contemporary and dark romance), science fiction, thriller, and cozy mystery have very high KU readership. In these genres, KU exclusivity often maximizes income from the existing audience.
Series with rapid release: authors who write and release books quickly benefit from KU because each new book drives page reads for all previous books; the series read-through multiplier is amplified.
Books priced under $5.99: KU may earn more per reader than a per-sale royalty on lower-priced books.

Going wide tends to perform better for:

Literary fiction and upmarket: Kobo and Apple Books readers read more literary titles; the KU audience skews toward specific commercial genres.
Nonfiction: nonfiction readers are more likely to own books (vs. borrowing in KU), and many professional nonfiction readers use non-Amazon platforms.
International markets: Kobo is dominant in Canada and Australia; Apple Books has global reach. Authors with significant non-US readership often find going wide essential.
Authors building long-term platform independence: relying entirely on Amazon creates business concentration risk; wide distribution diversifies income across platforms.
Books over $7.99: at higher price points, per-sale royalties are more attractive than KU page reads.

The hybrid approach

Many authors don't choose one strategy permanently; they adjust by book, series, and over time.

Series strategy: launch a new series in KDP Select to maximize KU launch velocity, then go wide after the series is complete (or after the KDP Select period for each book expires). This captures KU momentum at launch while eventually expanding the audience.

New release in KDP Select, backlist wide: some authors keep their newest books in KDP Select for the first 6-12 months to capture launch velocity, then move the book wide once initial KU sales taper.

Different books on different strategies: a standalone thriller in KDP Select, a wide-distributing nonfiction series, and a backlist fantasy series wide. Different books have different optimal strategies.

Making the switch: from exclusive to wide

If you're currently in KDP Select and want to go wide:

When your current 90-day enrollment period ends, do not renew. (You can opt out of auto-renewal in your KDP dashboard.)
Once the enrollment expires, upload your ebook to other platforms.
Allow time for the book to be indexed on each new platform.
Update your backlist's "also by" links and newsletter to mention the new availability.

Caution: don't upload to other platforms while still enrolled in KDP Select. This violates the exclusivity agreement. KDP can remove your book from their platform and potentially suspend your account for policy violations.

The financial reality: what matters most

The KDP Select vs. wide debate is often framed as a binary choice between two strategies with clear financial winners. In practice, the financials depend most on:

Your reader base: if your readers buy on Amazon, KDP Select maximizes income. If your readers use Kobo, Apple Books, or other platforms, wide distribution captures that income. Build data over time by testing both.

Your production pace: faster-writing authors benefit more from KDP Select's KU dynamics; the series flywheel spins faster with quick releases. Slower authors may benefit more from wide distribution's platform diversification.

Your genre's KU penetration: check your genre's communities and data; some genres run 50-80%+ of reads through KU, while others see KU readers as a tiny fraction.

Your long-term goals: if building platform independence matters, going wide eventually makes sense even if short-term income favors Select. Wide distribution is harder to build momentum on initially but creates less single-platform dependency.

Tracking your results to make data-driven decisions

The best way to evaluate KDP Select vs. wide for your specific situation is to collect data. A few approaches:

Run KDP Select for one series, wide for another: if you write in different genres or have two separate series, run them on different strategies for 6-12 months and compare total income, audience growth, and sustainability.

Track by month: after going wide, compare total monthly income (across all platforms) to your previous KDP Select income. Wide distribution typically takes 6-18 months to fully ramp up on non-Amazon platforms as each platform indexes and recommends your books. Early months of going wide often show lower income; income tends to grow as platform presence builds.

Normalize for book count: if you published more books during one strategy period, income comparisons need to account for the additional titles. Track average income per title to isolate the strategy effect.

Monitor KU page reads vs. sales: if you're in KDP Select, track the ratio of KU borrows to outright sales over time. If KU borrows are declining as a proportion of total earnings, the market may be shifting in ways that affect KDP Select's advantage for your genre.

Income diversification argument

The going wide vs. KDP Select decision isn't purely about which earns more. It's also about business risk.

Amazon holds significant market power in the ebook industry. Changes to Amazon's policies, KU's payment rate, or their recommendation algorithms directly affect KDP Select authors in ways they can't control. A sharp cut to the KU Global Fund (which Amazon sets at its discretion) directly reduces KDP Select income.

Wide authors who've built a meaningful presence on Kobo, Apple Books, and B&N have income that doesn't depend on any single company's decisions. In a year when Amazon cuts the KU rate significantly, a wide author's Kobo income continues unchanged.

Many successful long-term indie authors treat the going-wide question not just as "what earns more now" but "what creates a sustainable business I control." The answer frequently involves building wide distribution even if KDP Select is more profitable short-term.

Tools for managing wide distribution

Going wide adds account management complexity. Several tools help:

Draft2Digital: consolidates distribution to most non-Amazon platforms through one account and dashboard. Handles Kobo, Apple Books, B&N, library platforms, and others through one upload.

BookFunnel: helps with reader magnet delivery across platforms, ARC distribution, and direct sales (selling ebooks directly to readers through your own site).

Books2Read (D2D's Universal Book Link): creates universal links to your books that route readers to their preferred retailer. One link for social media works across all markets.

IFTTT/Zapier automations: authors who want to automatically notify their email list or post social content when a new book goes live on multiple platforms can set up automated workflows through tools like IFTTT.

Frequently asked questions

Can I test KDP Select for one book and go wide for another?

Yes. KDP Select is applied at the book level, not the account level. You can have some books in KDP Select and others wide simultaneously. Different books in a series can even be on different strategies, though this creates inconsistency in where readers can find the series.

If I go wide, will I earn less?

Not necessarily. Wide authors who've built audiences on multiple platforms can earn significantly more than their Amazon-only equivalent. The early phases of going wide often show lower total income as non-Amazon platforms build; over time, multiple revenue streams tend to produce more stable total earnings.

Can I be in KDP Select and publish a paperback or audiobook elsewhere?

Yes. KDP Select only covers ebooks. Your paperback can be on IngramSpark, your audiobook on ACX/Findaway, and your ebook exclusively on Amazon KDP, all simultaneously.

What's the right price for a KU book?

Pricing for KU doesn't directly affect page-read income (you earn per KENP regardless of list price). But your list price affects how many readers buy rather than borrow and your income from those who do buy. Many KU-enrolled authors price somewhat higher than they might otherwise, since KU readers don't see the list price as a purchase cost.

How does going wide affect my visibility on Amazon?

Amazon's algorithm primarily promotes books that perform well within Amazon's own ecosystem. Going wide doesn't directly harm your Amazon visibility, but if wide distribution reduces your Amazon-specific sales velocity (because some readers are now buying on Kobo or Apple Books instead), your Amazon algorithm signals may be slightly weaker. For most wide authors, the total income gain from other platforms outweighs any Amazon algorithmic effect, but this is the genuine tradeoff that wide authors accept.

Common mistakes with each strategy

Common KDP Select mistakes:

Automatically renewing KDP Select for years without re-evaluating whether it's still optimal for your genre and sales profile
Uploading to other platforms while still enrolled in Select (policy violation with significant consequences)
Assuming KDP Select is permanent and not building any non-Amazon reader relationships, leaving you with no alternative distribution options if Amazon's terms change

Common wide distribution mistakes:

Going wide without doing any marketing on the non-Amazon platforms; simply having a book on Kobo doesn't generate Kobo sales, any more than having a KDP listing generates Amazon sales without any marketing support
Setting prices on non-Amazon platforms and never updating them (prices drift out of alignment with your Amazon price over time as you run promotions on Amazon)
Ignoring platforms that account for most of your non-Amazon sales while spending time on platforms that generate almost no revenue

The bottom line

KDP Select is a legitimate strategy with real advantages, particularly for certain genres, fast-producing authors, and series fiction. Going wide is also a legitimate long-term strategy that builds platform independence and reaches readers on non-Amazon platforms. Both can be financially successful.

The most common path for first-time indie authors: start with KDP Select for the first book or series to capture KU momentum, then evaluate going wide once you have a reader base and understand your audience's platform preferences.

Summary: when to consider each strategy

Your situation	Consider this strategy
First book, genre with high KU readership	KDP Select initially
Series fiction in romance, fantasy, thriller	KDP Select for launch, evaluate after
Strong international reader base (Canada, Australia, UK)	Wide distribution
Nonfiction with professional audience	Wide distribution
Risk management and platform diversification	Wide distribution
Rapid release, books per year producing multiple titles	KDP Select for volume velocity
Desire for editorial control and independence	Wide distribution

No single row in this table is decisive on its own; the right decision combines your genre, your speed, your current earnings, and your long-term priorities. Revisit the question at least once a year as your publishing situation evolves.
