How to Upload Your Book on Amazon KDP

KDP is the gateway to the world's largest ebook marketplace. The upload process itself takes about 20 minutes, but the decisions you make on the way through, categories, keywords, description, and pricing, determine whether your book gets discovered. Here is how to get each one right.

Everything you need to upload your book on KDP

The KDP dashboard: three pages you need to know

KDP's upload flow is split into three pages. The Book Details page covers title, subtitle, series information, author name, description, keywords, and categories. The Content page is where you upload your manuscript and cover files, set DRM preferences, and preview the ebook. The Pricing page controls royalty rate, list price per territory, and KDP Select enrollment. Complete all three pages in order. You cannot skip ahead, and saving your progress on one page does not publish the book.

Choosing your BISAC categories

KDP gives you two categories at upload. Choose one broad category for long-term visibility and one narrow subcategory where you can realistically hit the top 100. Ranking in a subcategory earns a bestseller orange banner on your listing, which lifts click-through rates. After publishing, email KDP support to request up to 10 total categories. Research the top 100 in your target subcategory to gauge the sales rank required to place there. A subcategory with fewer competitors gives you a faster path to a visible badge.

Writing your book description in HTML

Amazon renders basic HTML in book descriptions. Use bold tags for your hook sentence and key selling points, paragraph tags for spacing, and italic for titles or emphasis. The description displays as approximately 600 characters on the mobile app before the See More cutoff, so put your strongest line first. Keep your full description under 4,000 characters. Avoid exclamation points, superlatives, and lines like Perfect for fans of, which Amazon's algorithm now penalises in some categories.

The 7 keyword fields: how to use them for discovery

Each keyword field accepts up to 50 characters. Use the full space. Enter phrases, not single words: long-tail phrases like 'enemies to lovers fantasy romance' outperform generic terms like 'fantasy'. Think about how readers search: they search by trope, setting, mood, and comparison titles. Avoid terms already in your title, subtitle, or categories since Amazon indexes those separately. Rotate keywords based on performance data from your KDP reports. The 7 fields give you roughly 350 characters of additional search indexing.

Pricing strategy for new authors

The $2.99 to $4.99 range maximises unit sales for debut authors while qualifying for the 70% royalty rate. Below $2.99 you drop to 35% royalty. Above $9.99 you also drop to 35%. Price the first book in a series at $0.99 or free to drive series read-through. Mid-list authors with an established readership price at $4.99 to $7.99. Genre expectations matter: thriller and romance readers tolerate lower prices; self-help and business readers accept higher ones. Check your genre's top 20 for price benchmarks.

KDP Select enrollment and the 72-hour review window

KDP Select enrollment is optional and requires 90-day ebook exclusivity. It unlocks Kindle Unlimited, Countdown Deals, and Free Book Promotions. For debut authors without an existing retailer presence, the Kindle Unlimited income stream is worth the exclusivity trade-off. The review window after upload is typically 24 to 48 hours but can extend to 72. Do not plan your launch date less than 96 hours after submission. Check your KDP dashboard for status updates rather than waiting for an email that may not come.

Frequently Asked Questions

How do I choose the right categories on KDP?

KDP gives you two BISAC categories at upload time, but you can request up to 10 by emailing KDP support after publishing. Choose your two main categories strategically: one broad category where you want long-term visibility and one narrow subcategory where you can realistically rank in the top 100. Ranking in a subcategory earns you a bestseller badge, which increases click-through rates significantly. Research competitor books to see which subcategories are achievable at your expected sales volume.

Can I use HTML in my Amazon book description?

Yes. Amazon's book description field accepts a limited set of HTML tags: bold (b), italic (em), paragraph (p), line break (br), heading (h3, h4, h5, h6), and unordered list (ul/li). Use bold to highlight your hook sentence and key selling points. Use paragraph breaks to make the description scannable. Do not use h1 or h2 tags or any CSS styling. Test your description in KDP's preview before publishing to confirm the formatting renders correctly.

What is the best price for a new author's Kindle ebook?

The $2.99 to $4.99 range is the standard sweet spot for new authors in most fiction genres. At $2.99 you earn 70% royalty (vs. 35% below $2.99) and the price is low enough to reduce purchase hesitation. At $4.99 you signal mid-range value without the sticker shock of $7.99+. Debut novels from unknown authors rarely succeed at $6.99 or above. If you have a backlist or a series, consider pricing the first book at $0.99 or free to drive series read-through.

Should I enroll in KDP Select?

KDP Select gives you access to Kindle Unlimited (KENP page reads), Kindle Countdown Deals, and Free Book Promotions in exchange for 90-day exclusivity on the ebook. For debut authors with no existing retailer presence, KDP Select is usually worth it: Kindle Unlimited readers are voracious and KENP income can exceed sale royalties for books that gain traction. The trade-off is that you cannot sell the ebook on Kobo, Apple Books, or any other platform during the enrollment period.

How long does KDP review take?

KDP states a standard review window of 72 hours, but most books go live within 24 to 48 hours for new titles. Updates to existing books (content changes, cover updates, price changes) are often processed within a few hours. Do not schedule a launch immediately after uploading. Give yourself at least four days between upload and your planned launch date to account for delays. Amazon does not notify you by email when the review is complete, so check your KDP dashboard.
