How to Format a KDP Book Description With HTML

Amazon KDP supports a limited set of HTML tags in book descriptions. Using them correctly can dramatically increase the visual impact and readability of your description — which directly affects conversion rates.

Steps

1

Know the supported tags

KDP supports: or (bold), or (italic),
(line break),

(paragraph),

–
(headings),
    and
      (lists),
    1. (list items). Tags not on this list are stripped from your description.

2

Write your description in a text editor

Write your description with HTML tags included. Example: A gripping thriller for fans of Gillian Flynn.

When detective Sarah Mills receives a package addressed to a dead woman, she doesn't know the investigation will consume the next three years of her life...

3

Paste into the KDP description field

Log into your KDP dashboard, navigate to your book's content page, and paste your HTML-formatted description directly into the "Book Description" field. Do not use a rich text editor — paste as plain text with HTML tags included.

4

Preview the result

After saving, go to your Amazon product page (or use KDP Preview) to verify the formatting rendered correctly. Allow 24–48 hours for description updates to appear on your live Amazon page.

5

Test with Amazon's Book Description Tool

Amazon provides a free Book Description Formatter at author.amazon.com — it lets you apply formatting and generate the correct HTML. This is the official and safest way to generate formatted descriptions.

Tips

  • Open with a bold hook sentence. Readers scan — the first bold line is what they read first. If it doesn't hook them, they won't read the rest.
  • Use
    • bullet lists in non-fiction descriptions to show "what's inside" — readers scan for benefits and bullet lists make them visible immediately.
    • Keep paragraphs short (2–4 sentences). Wall-of-text descriptions have dramatically lower conversion rates than well-formatted ones.
    • End with a CTA: "Download now and start reading tonight" or "Get your copy and join 10,000 readers who..." — a direct action prompt in the last line increases conversions.

FAQ

Does KDP description HTML affect Amazon SEO?

Amazon's search algorithm does index your description for keywords, but the weighting is lower than your title, subtitle, and backend keywords. Formatting primarily impacts human conversion rate, not algorithmic ranking.

How long should a KDP book description be?

Amazon shows approximately 600 characters before the "Read more" fold. Put your most compelling content in the first 600 characters. Total description can be up to 4,000 characters — use them all for non-fiction; fiction can often be effective at 1,500–2,500 characters.
