About the KDP Keyword Generator

On Amazon, readers find books by typing searches, and KDP lets you enter backend keywords alongside your title and categories to help match those searches. This free KDP keyword generator uses AI to brainstorm 50 search phrases for your book's niche so you have a long list to choose from.

Enter your book niche or topic and the book type (the box defaults to "ebook," but you can type paperback, low-content, journal and so on), then click Generate 50 keywords. The AI is asked for high-intent phrases that mix transactional searches, problem-aware searches (what a reader is struggling with) and phrases inspired by what tends to sell in that niche.

These are ideas, not data. The tool does not pull Amazon search volume, competition or sales figures. Every keyword is an AI suggestion, so validate the ones you like by typing them into Amazon's search bar, checking the autocomplete suggestions, and looking at how many books compete and how well they rank.

A worked example. Enter "ADHD productivity for adults" with book type "paperback." You get a list along the lines of focus planners, time management for ADHD adults, ADHD workbook, beating procrastination with ADHD and similar phrases. Click any keyword to copy it, or use Copy all to grab the full list (one per line) for a spreadsheet.

Turning 50 ideas into your seven boxes. At the time of writing, KDP gives you seven keyword boxes per book, and each can hold a short phrase (check KDP's current rules and character limits). Pick the most relevant, least-repeated phrases, avoid words already in your title, and never use other authors' names, brand names or misleading terms, which Amazon's guidelines prohibit.

Frequently asked questions

Does the KDP keyword generator show Amazon search volume?

No. The 50 keywords are AI-generated suggestions based on your niche and book type, with no search volume, competition or sales data attached. Check promising phrases in Amazon's search bar and autocomplete to see whether real readers search for them.

How many KDP keywords can I actually use from this list?

At the time of writing, KDP offers seven keyword boxes per book, each for a word or short phrase, so you will use only a handful of the 50 ideas. Check KDP's current help pages for the exact limits, and choose the most relevant phrases that don't repeat words already in your title.

Why does the KDP keyword generator ask for a book type?

The book type is sent to the AI along with your niche, so it can lean toward phrases that suit that format. For example, a low-content journal and a nonfiction ebook on the same topic attract different searches.

Which keywords should I avoid putting into Amazon KDP?

Amazon's guidelines prohibit things like other authors' names, trademarked brand names, misleading claims and time-limited promo phrases. Review the AI list and remove anything in those categories before you paste keywords into KDP.

Can I use the KDP keyword generator list for Amazon ads too?

Yes, the list works as a starting point for keyword ideas in Amazon advertising campaigns. Because it is AI-generated, test the keywords with a small budget and keep the ones that actually earn impressions and clicks.
