Amazon Search Suggestion Expander
This Amazon search suggestion expander turns one seed into the suggestions Amazon shows as shoppers type, then groups near-duplicates so the same niche is not listed twice — with how often and how high each one appeared.
What to do with the list
Each Amazon keyword suggestion here is a phrase shoppers were offered while typing — a sign of how people search, not a count of how many do. How Amazon search suggestions work explains what the list can and cannot tell you.
Keep the phrases that describe your book, then fit them into your title, subtitle and seven backend keyword boxes with the KDP Keyword Generator, or let Listing Studio draft the listing from the book itself.
Suggestions stop at wording. For category paths use the KDP Category Finder; to check whether a phrase is a niche, the KDP Niche Finder; and for the keywords a published book already ranks for, Reverse ASIN Lookup.
Frequently asked questions
Is this a Chrome extension?
No. This page is SmartKDP's free web tool: you type a seed here and the expansion runs here, so nothing changes inside Amazon's own search bar. (Several Chrome extensions use the same "suggestion expander" name for a widened dropdown on Amazon.com — a different product.) SmartKDP does have a browser extension, which runs deeper expansions from the Amazon page itself.
Where do these suggestions come from?
From Amazon's own search suggestions (autocomplete) — the same suggestions shoppers see as they type in the search bar. The expander explores the suggestions around your seed, then merges and deduplicates everything Amazon offered into one clustered tree.
Are these book keywords or all-of-Amazon keywords?
The expansion covers Amazon's store-wide search suggestions, so you see the full range of shopper phrasing around your seed. The Books question is answered separately: the paid analysis reports a Book Intent Ratio per keyword, so you can see which phrases are book-shaped and which are driven by other products.
What do “4 of 4 queries” and the percentile mean?
They are raw observations, not scores. “4 of 4 queries” means the suggestion appeared in all four of the searches in this run that could have shown it; “best #1” is its highest position in any suggestion list; the percentile is its standing against the other suggestions in this run — higher means it showed up more often and nearer the top. We show the facts Amazon returned rather than dressing them up as estimates.
Why cluster variants together?
“Coloring book adults” and “adult coloring book” are the same niche typed two ways. The expander groups close variants like these into one cluster, labeled with its most common phrasing, so your list reflects distinct opportunities instead of repeating the same one.
Does this show search volume?
Not on the free plan — and deliberately so. Amazon publishes no keyword volume, so any bare number here would be a guess dressed as a fact. The free tool shows exactly what Amazon returned. Estimated volumes, always shown as a range with a confidence level, are part of the paid research suite, and the methodology page explains how to read them.
How many free runs do I get?
A handful per day — the cap is what keeps the tool free. The counter above your results shows how many you have left. The browser extension runs deeper expansions.
Which marketplaces are supported?
Amazon.com, Amazon.co.uk, and Amazon.de, each expanded in its own language. More marketplaces will follow.
