How KeywordQuarry works

Amazon ranks every search term by how often shoppers search it — that's the Search Frequency Rank. Rank 1 is the most-searched term on Amazon; rank 100,000 is searched far less. Lower rank = more demand. KeywordQuarry tracks SFR weekly, so you can see demand rising or falling in days instead of months.

The Explorer is the core tool: search and filter roughly a million keywords by rank, estimated monthly volume, week-over-week movement, category, and competition. Set a demand floor, sort by the top-3 review average, and the least-competitive keywords with real volume rise to the top. Click any keyword for its full history.

For every keyword, Amazon reports the three products shoppers actually clicked most. KeywordQuarry averages the reviews of those three products — not every listing on the page — so the number reflects what you'd really compete against. Other tools average the whole results page, where irrelevant products with tens of thousands of reviews make winnable keywords look impossible.

The Explorer also flags keywords where none of the top 3 products use the term in their title — open lanes that are much easier to rank for.

SFR is a rank, not a count. KeywordQuarry calibrates rank against real search-volume data to estimate monthly searches for every keyword, so you can think in units and revenue instead of abstract ranks. Treat estimates as directional (±~30%).

Some keywords are artificially inflated by search and click bots. KeywordQuarry analyzes click and conversion patterns and flags suspicious keywords as warning or critical, and filters them out of your results by default — so you never build a launch on demand that isn't real.

Every keyword is mapped to its exact leaf category — not just “Health & Household” but “Magnesium Supplements.” The Category Builder lets you combine any leaf categories into custom buckets, so the Explorer returns only keywords from the niches you care about.

Star any keyword to your watchlist. Every week, after fresh data lands, you get one email digest showing how your keywords moved — so a spike never slips past you.
