Keyword ideas, not search-volume data — see what this tool does not do.
Keyword ideas
None selected
These are keyword ideas. This tool has no Amazon search-volume, competition, CPC or sales data, so none is shown. Check the ideas against Amazon's own search bar and your Search Query Performance report before you rewrite a listing.
What this tool does and does not do
It does: expand a product phrase into grouped keyword ideas — core variations, the way shoppers phrase a buying search, and longer-tail combinations built from the features and audiences you enter. Everything runs in your browser, so the same input always gives the same ideas.
It does not: provide Amazon search volume, search-frequency rank, competition scores, keyword difficulty, CPC estimates or sales estimates. It does not read Amazon autocomplete and it makes no network requests. If a tool shows you those numbers for free, check where they come from before you trust them.
It never invents product attributes. Type "water bottle" and you will not get "stainless steel water bottle" back — material, size and feature words only appear if you enter them yourself. That matters because a keyword describing something your product is not will cost you clicks and returns.
Turning ideas into a better listing
Keyword ideas are a starting list, not a plan. The useful next step is narrowing them to terms that genuinely describe your product, then deciding where each one belongs.
Check demand before you commit
Type the promising ideas into Amazon's own search bar and watch what it suggests — that tells you the phrasing shoppers actually use. If you have Brand Registry, the Search Query Performance report shows impression, click and purchase share for the queries already reaching your ASIN, which is real first-party data rather than an estimate.
Put each keyword where it earns its place
The title carries the terms that matter most and still has to read like a sentence a person would say. Bullets carry secondary terms alongside the benefit they support. Backend search terms take the variants, misspellings and synonyms that would clutter the visible copy. A keyword only needs to appear once to be indexed — repeating it does not rank you higher, it just makes the listing worse to read.
Relevance beats reach
Ranking for a term you do not deserve produces clicks that do not convert, and conversion rate is part of how Amazon decides what to show. A smaller set of accurate keywords generally outperforms a long list of loosely related ones.
