Is KDP really free to publish on?

Yes, 100% free upfront. No monthly fees, no annual fees, no submission charges. Amazon takes their cut (30% on the 70% royalty tier, 65% on the 35% tier) only when your book sells. The only optional costs are an ISBN (£91 from UK ISBN agency, though Amazon provides a free ASIN that works for Kindle), professional cover design (£100-£500), and promotional advertising (entirely optional).

Do I need an ISBN for KDP?

No. Amazon provides a free ASIN (Amazon Standard Identification Number) for every Kindle book that works as the eBook's identifier within their store. ISBN is only required if you want to publish print versions through KDP's paperback option, or if you want the book trackable in industry databases like Nielsen BookData.

Can I publish content I created on YouTube without copyright issues?

Yes, completely. Your YouTube videos are your copyrighted content. You can convert them, expand them, restructure them, and republish them on KDP without any issue. If your videos include licensed music, third-party clips, or interview guests, those rights are separate — the AI conversion typically removes music but you'd need explicit guest consent for republishing interviews.

How long does it take from KDP upload to book being live?

Most books go live within 24-72 hours after submission. Amazon's automated review catches obvious issues (copyright, formatting, metadata problems); manual review only happens if the automated check flags something. For new authors, expect the first book to take 48-72 hours; subsequent books often go live in under 24 hours.

What's the difference between KDP and Amazon KDP Select?

KDP is the basic free publishing program — upload your book, distribute via Amazon Kindle, keep 70% royalty in the £2.99-£9.99 range, and you can sell the same book on Gumroad, Google Play Books, Apple Books, and elsewhere. KDP Select is an optional add-on requiring 90-day Amazon exclusivity in exchange for Kindle Unlimited inclusion and promotional tools. For most creators KDP without Select is the right choice.

How to Self-Publish on Amazon KDP from YouTube Content

Amazon KDP (Kindle Direct Publishing) is the largest eBook marketplace in the world. For YouTube creators with monetisable content, getting a book live on KDP is one of the highest-leverage moves you can make. Here's the complete workflow.

How do you set up a KDP account?

Go to kdp.amazon.com and sign in with an existing Amazon account or create one. Setup takes 20-40 minutes including:

Author/publisher name (your real name, pen name, or brand)
Tax interview (US W-9 if you're a US person, W-8BEN if international — this prevents 30% US withholding on royalties)
Bank account details for royalty payments
Two-factor authentication setup

Once submitted, KDP approves most accounts within 24-48 hours. International creators outside the US, UK, EU, Australia, and a handful of other supported countries should check whether KDP supports their banking.

How do you convert YouTube content into a KDP-ready eBook?

The pragmatic workflow:

Pick the videos to convert — typically 5-12 of your strongest, evergreen videos on a coherent topic
Run them through an AI conversion tool (YouTube to eBook accepts playlist URLs and produces a complete multi-chapter book)
Edit the draft to remove video-specific references ("as I mentioned last week") and harmonise voice across chapters
Add a real introduction (200-500 words) and conclusion (200-400 words) — these aren't in the video content
Generate or commission a cover image (1600x2560 pixels, JPEG, under 50MB)
Export as EPUB

Total time from raw videos to KDP-ready files: 8-16 hours depending on editorial standards. Compare to writing the equivalent book from scratch (typically 80-150 hours).

What's the right file format for KDP upload?

EPUB is preferred. KDP also accepts DOCX, but EPUB gives you precise control over formatting. Most AI conversion tools (YouTube to eBook included) export EPUB directly. Avoid uploading PDF for KDP — Kindle readers handle reflowable EPUB much better than fixed-layout PDF.

For your cover, use JPEG at 1600x2560 pixels (the recommended Kindle aspect ratio). Test the cover at thumbnail size — it needs to read clearly when small in search results.

How do you set pricing on KDP?

KDP has two royalty tiers:

70% royalty — books priced £2.99-£9.99 keep 70% of the cover price after delivery fees
35% royalty — books outside £2.99-£9.99 keep only 35%

The math heavily favours staying inside the 70% band. A £14.99 book at 35% earns less per copy than a £9.99 book at 70%. Most creator eBooks are priced £4.99-£9.99 specifically to maximise the royalty tier.

For the absolute best earnings, set the price to £9.99 — the highest end of the 70% band — unless you're targeting impulse purchases (£2.99-£4.99 sweet spot for shorter content).

Should you join KDP Select?

Probably not, if you have a YouTube audience. KDP Select locks you into Amazon-exclusive distribution for 90-day enrolment periods in exchange for:

Kindle Unlimited access (readers pay subscription, you get paid per page read)
Countdown Deals and Free Promotion days
Higher 70% royalty in India, Brazil, Mexico, Japan (which otherwise get 35%)

The exclusivity cost is high — you lose Gumroad direct sales, Google Play Books, Apple Books, Kobo, and your own website. For creators with an existing audience, that cost almost always exceeds the KDP Select benefits.

KDP Select makes sense if you're starting from zero audience and need Amazon's algorithmic boost. It doesn't make sense for established creators.

How do you optimise the KDP listing?

Three highest-impact areas:

Title and subtitle — the title is what catches attention; the subtitle is where your keywords live. "Async Productivity: The Calm Tech Worker's Guide to Deep Work, Meetings That Don't Suck, and Shipping Without Stress" outperforms "Async Productivity" alone.
Description — first 200 characters are what shows in mobile search results. Lead with the specific problem you solve and the audience you solve it for. Use HTML formatting for paragraphs and bullet lists in the longer description below the fold.
Categories and keywords — pick 2 categories deep into the taxonomy (more specific = less competition), and use all 7 keyword slots with specific long-tail phrases your audience actually searches.

What's a realistic income expectation?

Honest numbers for KDP specifically:

First 90 days with no marketing: £30-£300 total per book
After 12 months with passive YouTube promotion: £100-£800/month per book
Active promotion + multiple books in the niche: £500-£4000/month total
Top-performing creator KDP businesses: £5000-£20,000/month across multiple titles

KDP's audience is enormous but discovery is competitive. The creators earning well combine KDP with active YouTube promotion, email list marketing, and (often) running 4-10 books rather than relying on one hit.
