Free KDP keyword box tool

Paste the phrases a reader would type for your book, most important first. We pack them into KDP's seven keyword boxes, drop words your title already covers and leave out anything KDP forbids. The tool works only from what you type; it looks nothing up on Amazon.

What KDP forbids in keywords

From KDP's keyword guidelines — the tool flags these automatically:

• Other authors' names and other books' titles.
• Brands and trademarks you don't own (Harry Potter, Disney, For Dummies…).
• Amazon programme names: “Kindle Unlimited”, “KDP Select”.
• Time-sensitive words (“new”, “on sale”) and quality claims (“best”, “bestseller”, “#1”).
• Quotation marks, HTML, and words already in your title, subtitle or categories.

How to choose the phrases

1. Write down 10–20 ways a reader would search for a book like yours: genre, sub-genre, tropes, setting, audience. Typing a few of them into Amazon's search box yourself shows how readers phrase them.
2. Keep only phrases that honestly describe your book, and mix broad ones with specific ones.
3. Put the most important first: the tool gives each phrase its own box while boxes last.
