Amazon Keyword Tool
Helps sellers discover the search terms shoppers use on Amazon to optimise listings, PPC campaigns, and product research.
If you have ever picked a keyword on a low competition score and still failed to rank, you already know the number is not the whole story.
Key points
- Cross-check free tool data from multiple keyword research tools with Amazon autocomplete and competitor listings.
- Treat search volume and difficulty scores as directional estimates, not facts.
- Place amazon search keywords naturally in titles, bullets, and descriptions — stuffing hurts conversion.
- Refresh your keyword list regularly as marketplace behaviour and Amazon’s signals change.
- Use reverse ASIN lookup to uncover terms competitor products already rank for.
A seller discovers a keyword gap through reverse ASIN lookup
A seller of reusable water bottles uses a free Amazon keyword tool to generate terms from the seed 'insulated bottle'. The tool returns 'stainless steel water bottle' with an estimated monthly search volume of 8,000 and a competition score of 6 out of 10. The seller runs a reverse ASIN lookup on a competitor’s top-selling listing and finds 'double wall vacuum flask' — a long-tail keyword with 1,200 monthly searches and a competition score of 3. By targeting the lower-competition term in their title and PPC campaign, they achieve a top-10 ranking within three weeks.
Three ways it goes wrong
- Irrelevant keywords Targeting popular terms that do not match your product hurts conversion and listing quality. Amazon’s algorithm penalises mismatched traffic.
- Single-tool reliance Using only one free tool misses cross-validation. Autocomplete, competitor data, and Amazon-native analytics together give a fuller picture.
- Static keyword lists Search volume, competition, and ranking signals shift over time. A list from six months ago may no longer reflect current shopper behaviour.
Four things it is not
- Not a ranking guarantee A low competition score estimates effort, not outcome. Your listing still needs good content, images, and reviews to convert.
- Not a replacement for PPC data Free tools give directional volume, not the conversion data you get from Amazon Advertising reports. Use both for budget decisions.
- Not a one-time task Amazon changes autocomplete behaviour and search signals over time. Keyword research should be refreshed every few months to account for shifting shopper intent, new competitors, and seasonal trends.
- Not a substitute for marketplace awareness Keyword behaviour differs by country and language. A tool set to US Amazon will not reflect UK or German shopper intent.
What to check before acting
- Cross-check with autocomplete Amazon’s own autocomplete shows real shopper queries as they type. Compare your tool’s suggestions against these live queries to validate relevance and catch terms the tool missed.
- Review competitor listings Check which keywords top-ranking products use in their titles and bullets. Reverse ASIN lookup tools can automate this.
- Verify marketplace selection Ensure your tool is set to the correct marketplace. Volume and competition vary significantly between Amazon.com and Amazon.co.uk.
