The KDP Select vs wide publishing decision is one that every author publishing on Amazon has to make for every book — and it is one that many get wrong, often because they follow advice that applies to someone else’s genre or audience rather than their own. This article gives you the framework to make the right call for your specific situation.
For context on how this decision fits into the broader publishing picture, see our complete beginner’s guide to self-publishing on Amazon KDP.
What KDP Select Actually Is
KDP Select is an enrolment programme — it is entirely optional and you choose it on a book-by-book basis. Enrolling means agreeing that your eBook will be available exclusively on Amazon for rolling 90-day periods. You cannot sell or distribute the eBook on any other platform during enrolment — not Apple Books, not Kobo, not your own website, not anywhere.
Physical formats (paperback and hardcover) are not affected by KDP Select enrolment. The exclusivity applies only to the digital version. You can have a paperback available through any channel you like while your eBook is in Select.
Enrolment renews automatically every 90 days unless you opt out. You need to remember to cancel before the renewal date if you want to leave — there is no grace period and no refund if you miss it.
What You Get with KDP Select
Kindle Unlimited inclusion. Your book becomes available to Kindle Unlimited subscribers, who can read it as part of their monthly subscription. You earn a royalty based on pages read — historically around $0.004–$0.005 per page — drawn from the monthly KDP Select Global Fund. In genres with strong KU readership, this can generate significant income alongside direct sales.
Kindle Countdown Deals. A time-limited price promotion with a live countdown timer on your Amazon product page. Readers see that the price will increase and the urgency often drives conversions. Importantly, you retain your 70% royalty rate during a Countdown Deal even if your promotional price is below $2.99 — a rare exception to the standard tier rules.
Free Book Promotions. Up to five days per 90-day enrolment period during which your book is available for free. Downloads of free books improve your book’s ranking and can drive significant visibility. Combining a free promotion with listing services like Freebooksy or BookSends amplifies the impact considerably.
What Exclusivity Costs You
The cost of KDP Select enrolment is the revenue from every non-Amazon platform. Apple Books and Kobo are the most significant: Apple Books has a large readership particularly in the US, UK, and Australia; Kobo has dominant market share in Canada and a strong presence in the UK.
For authors whose readership is heavily Amazon-centric — which is typical in some genres and less so in others — this cost can be genuinely small. For authors with an established wide readership, or for those building a long-term multi-platform business, losing non-Amazon revenue is a genuine strategic cost.
What Wide Publishing Means
Publishing wide means your eBook is available on multiple platforms simultaneously. There is no Amazon-equivalent programme requiring exclusivity on other platforms — you simply upload to each one and collect royalties from all of them independently.
Wide publishing requires more administrative work: separate accounts, separate dashboards, separate metadata management. This is where aggregators become valuable.
The Major Non-Amazon Platforms
- Apple Books: Large readership in English-speaking markets. Strong in romance, literary fiction, and non-fiction. Pays 70% royalty at most price points.
- Kobo: Dominant in Canada, strong in the UK and Australia. Popular with serious readers. Has its own subscription service (Kobo Plus) similar to KU.
- Google Play Books: Global reach, strong in emerging markets and Android-heavy regions. Pays 52% of list price.
- Barnes & Noble Press: Primarily a US platform. Declining market share but still meaningful for US-focused non-fiction.
- Smashwords/Draft2Digital: Both distribute to multiple smaller retailers including libraries via OverDrive and Bibliotheca.
Aggregators vs Direct Upload
You can upload directly to each platform or use an aggregator like Draft2Digital to distribute to multiple platforms from a single upload. Draft2Digital takes a percentage of sales (typically 10–15%) in exchange for handling distribution, formatting conversion, and reporting across all connected platforms.
For most authors going wide for the first time, an aggregator is the right starting point — the administrative simplification is worth the percentage. Authors with significant sales on specific platforms sometimes switch to direct uploads on those platforms to capture the full royalty rate.
Which Works Better by Genre
Genre matters more than almost any other factor in this decision.
Genres that tend to perform better in Select (high KU readership): romance, erotica, paranormal romance, fantasy, science fiction, thriller, cosy mystery. Readers in these genres subscribe to KU specifically to consume high volumes of content. Prolific authors in these categories often earn more from page reads than from direct sales.
Genres that tend to perform better wide (lower KU readership): literary fiction, narrative non-fiction, self-help, business, children’s books, cookbooks. Readers in these categories are more likely to buy outright than subscribe. Apple Books and Kobo often generate meaningful revenue for these authors.
How to Decide
Start with KDP Select for your first book if you are publishing in a KU-heavy genre, or if you simply want to simplify your launch and focus on one platform while you learn the system. Review after each 90-day period based on actual data, not assumption.
Consider going wide when: you have a back catalogue that could benefit from additional platform exposure; your genre has meaningful non-Amazon readership; or you are building toward a diversified income model that does not depend entirely on Amazon’s algorithm and policies.
Use a KDP research tool like KDP Rank Fuel to analyse your keyword and category options on Amazon first — understanding your Amazon positioning clearly helps you judge how much incremental value wide publishing would add.
Whichever route you choose, your manuscript needs to meet the quality standard that readers on every platform expect. A manuscript editing and proofreading service ensures your book is ready for any platform you choose to publish on.
