Keyword research for Amazon.com
Find the best Amazon.com keywords for your book. Our tool searches real Amazon autocomplete data and search volume databases to surface the keywords US readers actually use when looking for books in your genre.
Use this route when you want keyword ideas that are anchored to the actual marketplace you are targeting, not generic Amazon advice that ignores local language and search behaviour.
How it works
The flow should be simple enough to use quickly and structured enough to produce a useful publishing decision.
Anchor the research to one marketplace
Search language, competition, and seasonal demand differ enough by market that the first decision should be where the listing needs to win.
Build a tighter keyword set
Use the tool to surface stronger long-tail phrases, then keep the final list specific enough to rank and commercial enough to convert.
Carry the winners into launch
The best keywords should inform the title, description, and ad plan so the listing and traffic strategy pull in the same direction.
Research tool
Build the metadata around the market you actually want to rank in.
A keyword that looks fine in one Amazon store can be weak, over-competitive, or linguistically wrong in another. This route keeps that market context visible while you build the seven KDP keyword slots.
Market notes
Amazon.com Keyword Research for US Authors
These notes focus on how readers in this market search, how competitive the store is, and what language patterns are worth reflecting in the final keyword set.
Amazon.com is the world's largest book marketplace, and keyword optimization is the single most impactful action you can take to improve your book's discoverability. KDP allows 7 keyword fields of up to 50 characters each — that's 350 characters of prime real estate that directly influences whether readers find your book when they search.
The US market has the highest keyword competition of any Amazon marketplace. Generic keywords like "romance novel" or "thriller book" are dominated by established authors with thousands of reviews. The key is finding long-tail keywords — 3-5 word phrases that are specific enough to rank for but still have meaningful search volume. "Enemies to lovers fantasy romance" will convert better than "romance" alone.
Amazon's A9 search algorithm indexes your title, subtitle, and all 7 keyword fields. Keywords in your title carry the most weight, followed by subtitle, then keyword fields. Don't repeat words that already appear in your title — use your keyword slots for additional terms that readers search for but wouldn't fit naturally in a title.
Seasonal keyword trends matter in the US market. "Beach read romance" surges in May-August, "cozy mystery" peaks in October-December, and "self-help books" spikes every January. Updating your keywords seasonally can capture these traffic waves. Our tool shows current search volumes to help you identify what's trending now.
Competitor keyword analysis is one of the most effective strategies. Look at the top 10 books in your target category on Amazon.com — what words appear in their titles and subtitles? These are likely high-performing keywords. Enter those terms into the tool above to discover related keywords and their search volumes.

Once the keywords are right, tighten the description and category choices.
Keyword research is only valuable if the rest of the product page reflects the same search promise. Keep the positioning aligned before the listing goes live.
