Guide For Online Book Publishing Platforms in the USA: KDP, Wide, KU & Distribution

Choosing where to publish online is no longer as simple as “Amazon or not.” The real decision is about control, visibility, and scalability. Every author must decide between staying exclusive with KDP Select or distributing “wide” through multiple platforms. These choices directly affect revenue flow, series growth, and how easily readers can discover your books across digital and print formats.

Most first-time authors assume Amazon KDP is the only option, but that’s rarely true. Each platform has its own rules, promo tools, and data insights. KDP Select offers Kindle Unlimited (KU) exposure but locks your eBook for 90 days. Going wide builds long-term stability but takes more setup work. The right decision depends on your genre, release rhythm, and how much control you want over pricing and distribution.

At Estorytellers, we’ve guided over 200 authors across both exclusive and wide paths. We don’t just publish books; we map entire strategies around reader behavior, analytics, and growth. To make those decisions easier, we maintain ready-to-use tools like:

• Wide vs Exclusive Decision Tree
  
• KU Program Planner
  
• Promo Decision Grid
  
• KENP Read-Through Calculator
  
• Series Growth Playbook
  
• Distribution Path Map comparing KDP Expanded and IngramSpark

These frameworks help authors see the real levers behind their sales data rather than chasing trends. This guide walks through each of them, step by step, so you can make confident, data-backed choices for your book’s digital future.

Prepared by Estorytellers, a US-focused team that has launched 200+ titles both wide and exclusive, helping authors grow consistent sales with sustainable publishing systems.

KDP Only or Go Wide? Make a Decision, Not a Default

Many authors publish their books online without a clear plan. They pick Amazon KDP because it looks simple, but that choice can limit future options. Before you upload your book, you need to decide whether to go exclusive with KDP Select or publish wide across several online book publishing platforms.

What “Wide” Actually Means

Publishing wide means making your book available beyond Amazon. You can use platforms like Apple Books, Google Play Books, Kobo, and Barnes & Noble Press. You can also use digital book publishing aggregators such as Draft2Digital or PublishDrive to reach all these retailers from one dashboard.

Pros of Going Wide:

• Your book reaches more global readers.
  
• You have control over pricing and promotions.
  
• Your income isn’t tied to one platform’s algorithm.
  
• You protect yourself if Amazon changes its policies.

Cons:

• More setup and management.
  
• Sales may grow slower in the beginning since KU readers can’t access your book.

Exclusive to KDP

If you publish your eBook exclusively through KDP Select, Amazon rewards you with added tools like:

• Kindle Unlimited (KU) visibility
  
• Free Book Promotions and Countdown Deals
  
• Easier discoverability for new authors

The trade-off is that your eBook stays exclusive to Amazon for 90 days. You can still sell print copies anywhere, but the eBook cannot appear on other stores during that time.

Expert Insight

“Pick the ecosystem that matches your reader’s path, not your fear or FOMO.”
— Platform Strategy Lead, Estorytellers

At Estorytellers, we use real sales and reader data to decide whether exclusivity helps or hurts your long-term reach. We help authors switch smartly when their audience and revenue data indicate it’s time.

Wide vs Exclusive Decision Tree

Input Factor	If TRUE → Start Exclusive	If TRUE → Start Wide
Genre sells well in KU (Romance, Fantasy)	✅
Audience reads on Apple, Kobo, or Google Play		✅
You have a mailing list or strong social media		✅
You’re releasing a series fast (every 2–3 months)	✅
You plan to target libraries or schools		✅
You want to test KU benefits first	✅
You want full control of pricing		✅

Rule: Start where the data favors you. Reevaluate every 90 days.

This helps new authors see that online book publishing is a strategic decision, not a one-time upload. At Estorytellers, we guide authors through this entire process, building long-term publishing plans, not just listings.

Case Study

A romantasy trilogy author started with KDP Select to gain early traction. KU readers generated enough income to fund ads for Book 2 and Book 3. Once the trilogy was completed, the author shifted to wide distribution, running global promos on Apple and Kobo. Within six months, wide sales outpaced KU’s income and opened new international markets.

Understand KDP Select / Kindle Unlimited Rules Before You Click

Many authors join KDP Select without fully understanding the rules. Missteps can cost visibility, income, or even eligibility for promotions. Before committing, you need to know what exclusivity means, when KU is profitable, and when going wide across online book publishing platforms makes more sense.

The Non-Negotiables

• 90-day exclusivity for eBooks: During this period, your eBook cannot appear anywhere else, including Apple, Kobo, or Google Play.
  
• Print books are separate: You can still publish paperbacks or hardcovers through other channels.
  
• Website and newsletter excerpts allowed: Small samples or chapters can be shared, but not full copies.

When KU Makes Sense

KDP Select is most effective for:

• Genres with high serial consumption, like romance, fantasy, or mystery.
  
• Authors releasing a series quickly, where read-through analytics (page reads in KU) drive revenue.
  
• Shorter books where page-reads accumulate faster.

When Wide is Smarter

Publishing wide works best if:

• Your books are picture books or illustrated, which have fixed layouts.
  
• You target readers on Apple, Kobo, or Google Play.
  
• You want more control over pricing and promotions.
  
• You plan library or educational sales outside Amazon.

Expert Insight

“KU pays on pages read. The money comes from read-through, not just single-title spikes.”
— KU Program Manager, Estorytellers

At Estorytellers, we analyze each title’s genre, length, and audience to decide if KU exclusivity will increase income or if wide distribution will reach more readers. This strategy ensures authors don’t miss revenue opportunities or limit their brand growth.

KU Program Planner

Item	Details / Action
90-Day Term Start	Note the start and end date of KU exclusivity
Exclusivity Checklist	Confirm eBook isn’t uploaded elsewhere
Content Allowances	Note permissible excerpts for website/newsletters
Switch Decision	Evaluate at day 70 whether to remain exclusive or go wide
Marketing Windows	Plan Free Days or Countdown Deals during KU

Knowing this information ensures authors understand digital book publishing rules and can choose the right distribution strategy for their goals. Estorytellers helps authors map KU potential vs wide reach and optimize income without breaking rules.

Mini Case Study

An urban fantasy author enrolled in KU with a 5-book series. By tracking read-through across the series, KU income tripled compared to standalone releases. Meanwhile, a business nonfiction book performed better on wide distribution, using Apple and Google promotions to reach its target audience.

Promos: Select Tools vs Simple Price Edits

Promotions can make or break early traction for your eBook. Many authors underutilize KDP Select promotional tools or misapply price edits when publishing wide. Knowing when and how to use Free Days, Countdown Deals, or simple price edits can increase visibility, reviews, and sales without hurting your book’s perceived value.

Inside KDP Select

• Free Days: Temporarily make your book free to attract downloads and early reviews. Ideal for launching Book 1 in a series.
  
• Countdown Deals: Reduce price for a set period while keeping some revenue. Good for boosting rank and discovery.
  
• Scheduling Tips: Align promotions with newsletters, cross-promotions, or global time zones to maximize impact.

Outside Select or for Print

• Straight price edits for wide eBook distribution or print versions.
  
• Limited-time bundles for boxed sets or multiple books.
  
• Permafree for Book 1 in a series, but only if the math shows higher long-term revenue.

Decision Rules

• Use Free Days to seed reviews and early visibility.
  
• Use Countdown Deals to improve paid rank while preserving price perception.
  
• Use straight price edits when your book is not in Select or to coordinate cross-platform promotions.

Expert Insight

“Promos are levers, not holidays. Tie each to a measurable follow-on, like read-through or conversion.”
— Promo Strategist, Estorytellers

At Estorytellers, we help authors plan promotions that align with online book publishing platforms, maximizing visibility without diluting brand value. Our team sets schedules, KPIs, and ethical review practices to ensure every promo is strategic, not random.

Promo Decision Grid

Goal	Tool	Term	KPI to Watch
Reviews	Free Day	KDP Select only	Download count, early reviews
Rank Boost	Countdown Deal	KDP Select only	Paid rank, units sold
Read-Through	Free Day + Countdown	Series launch	Pages read, Book 2 conversions
Wide Distribution	Price Edit	Any platform	Sales per retailer, ranking

This section equips authors with clear guidance on promotional strategies for digital book publishing. Estorytellers ensure every promo leverages data, maximizes KU/page-read potential, and aligns with platform rules.

Mini Case Study

A romance series author used a Free Day on Book 1, followed by a Countdown Deal on Book 2. This combination lifted series revenue by 22% without changing perceived book value. Reviews and rankings improved across Amazon and other platforms.

[How It All Turned Out]

KU Page-Reads (KENP): Measure What Matters

For authors using KDP Select or Kindle Unlimited (KU), understanding KENP page-reads is critical. It is not just units sold that matter, but how many pages readers finish. Digital book publishing success relies on maximizing read-through and tracking series performance.

Reading Economics

• KU pays per page read, not per sale.
  
• A high number of downloads with low page completion may not generate meaningful revenue.
  
• Track page-reads alongside units sold and ad spend weekly to spot trends.

Series Diagnostics

• Monitor the funnel: % of readers finishing Book 1, then pages read in Book 2, and so on.
  
• Identify drop-offs caused by cover design, blurb mismatch, pacing, or pricing.
  
• Adjust content, metadata, and promo strategies based on insights.

Expert Insight

“A good KU week is measured by pages and units moving together. Spikes without finishers are noise.”
— Data Analyst, Estorytellers

At Estorytellers, we help authors track KU page-reads, calculate read-through rates, and make strategic changes to improve series engagement. We integrate analytics into the online book publishing process so authors can act on data instead of guesswork.

KENP Read-Through Calculator

Input	Value
Pages per Book	250
Readers per Week	1200
Conversion to Next Title	35%

Output	Value
Read-Through %	42%
Revenue per Series Starter	$1,540

Now you understand how page-reads impact revenue and help them optimize series performance on Amazon. Estorytellers guides authors to maximize digital book publishing ROI with precise tracking and actionable insights.

Case Study

A fantasy author reworked Book 1’s blurb and added a clear call-to-action at the end. Book 2 read-through increased from 41% to 55%, resulting in higher KU revenue and better engagement across the series.

Series Setup & Read-Through 

In online book publishing, series performance is a major revenue driver. Readers rarely buy a single book in isolation. How you structure metadata, pricing, and cadence directly affects digital book publishing success and reader retention.

Metadata Plumbing for Series

• Ensure the series title and numbering match exactly across Kindle, print, and wide distribution.
  
• Verify the series page on Amazon and other online book publishing platforms.
  
• Include back-matter CTAs that direct readers to the next title or the series page.
  
• Check that series metadata reflects the genre and reader intent, which improves discoverability.

Pricing Cadence and Anchoring

• Anchor prices for later books to maintain perceived value.
  
• Book 1 can be discounted or permafree strategically to seed reviews and encourage series read-through.
  
• Avoid aggressive underpricing of subsequent books to prevent eroding revenue.
  
• Consider using Estorytellers’ pricing frameworks to align KU/Kindle pricing with series strategy.

Launch Rhythm and Branding

• Release books on a regular cadence instead of waiting for perfection. Regular releases improve engagement.
  
• Maintain consistent cover branding to reinforce recognition across all digital and print editions.
  
• Use pre-orders for upcoming titles to build momentum and anticipation.
  
• Monitor reader behavior and series progression using analytics to optimize the next release.

FAQs

What is the best choice: KDP exclusive or wide online book publishing?

Choosing between KDP exclusive and wide depends on your goals. Exclusive gives access to KDP Select tools and Kindle Unlimited page-reads but locks your ebook for 90 days. Wide lets you reach Apple, Google Play, Kobo, and more. At Estorytellers, we help authors map the Wide vs Exclusive Decision Tree, ensuring your digital book publishing strategy matches your audience and maximizes revenue.

How do KDP Select and Kindle Unlimited work for authors?

KDP Select requires 90-day ebook exclusivity with Amazon. You earn via Kindle Unlimited (KENP) page-reads and can run Free Days or Countdown Deals. It’s ideal for serial fiction or high-read-through books. Estorytellers helps authors plan KU campaigns, track page-reads, and make sure online book publishing decisions support series growth and consistent revenue.

How should I run promotions for my ebook?

Promotions differ if you are in KDP Select or wide. Use Free Days or Countdown Deals within Select, and straight price edits or permafree first books outside Select. At Estorytellers, we use a Promo Decision Grid to align goals like reviews, ranking, and series read-through with the right tools for maximum impact in digital book publishing.

How can I track Kindle Unlimited page-reads effectively?

Track KENP page-reads weekly alongside unit sales to see series read-through. This identifies where readers drop off. Estorytellers provides a KENP Read-Through Calculator so authors can measure engagement, optimize metadata, and plan online book publishing strategies that improve conversions and overall series performance.

What is the best approach for print distribution beyond Amazon?

You can use KDP Print with Expanded Distribution for basic reach or IngramSpark for bookstore and library access. Many authors combine both for maximum visibility. Estorytellers helps plan ISBN, metadata, and distribution strategy to make your digital and print book publishing work seamlessly across platforms.
