Amazon Keyword Suggestion Expander

From Amazon's own search-suggestion (autocomplete) service — the same suggestions shoppers see as they type in the search bar. We ask it systematically: your seed, the seed with a trailing space, a curated set of modifier probes, and every a–z continuation, then merge and deduplicate everything it returned.

The expansion queries Amazon's All Departments suggestions — the index with real breadth; Amazon's Books-scoped suggestion index is nearly empty for most niches, which is why Books-only tools miss most of a niche. The Books question is answered separately: the paid analysis re-runs the same queries against the Books-scoped index and reports a Book Intent Ratio per keyword, so you can see which phrases are book-shaped and which are driven by other products.

They are raw observations, not scores. “4 of 4 queries” means the suggestion appeared in all four of the queries it could have appeared in; “best #1” is its highest position in any suggestion list; the percentile is its standing within this run, ordered by how broadly and how high it appeared. We show the facts Amazon returned rather than dressing them up as estimates.

“Coloring book adults” and “adult coloring book” are the same niche typed two ways. We fold word order and simple plurals into one cluster with the most-seen form as its label, so your list reflects distinct opportunities instead of repeating the same one.

Not on the free tier — 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 with honest confidence bands (built from how often and how high a term appears across the whole expansion) are coming to the paid research suite, with the methodology published.

A handful per day — each run fans out into dozens of requests on our side, so 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 (including a–z prefixes and word-prefix probes) straight from your own browser.

Amazon.com, Amazon.co.uk, and Amazon.de at launch, each with its own locale alphabet — the German expansion includes ä, ö, ü, and ß continuations. More marketplaces are configuration, not new code, and will follow.
