About Mettra Keywords
Mettra Keywords is an Amazon keyword research tool that works right on amazon.com. Open it on any Amazon page to find keywords worth ranking for, see which ones are worth paying for, and decide what to bid, without switching tabs.
SEARCH BY KEYWORD OR ASIN
• Enter a keyword or search term to get related keywords with their search volume and trends
• Enter one or more ASINs to see the keywords your competitors' listings get traffic from
• Every keyword gets a High, Medium or Low Opportunity label, based on demand and competition
• Spot high-buyer-intent keywords and fast-growing search terms early
• A relevance score shows how closely each keyword matches your product, so you skip the ones that bring the wrong traffic
• Filter, sort and pick keywords in one table
AGENT REPORT: SEMANTIC MARKET ANALYSIS
Mettra's AI agent reviews the keyword set and writes a short market report:
• Potential Targets: keywords worth putting effort into
• Potential Drains: keywords likely to spend budget without paying off
• Growth Hypotheses: ideas to test for growing sales
• Product Improvement Ideas: what shoppers are looking for that the products in the market don't offer

• Bookmark searches and come back to them in one click
• Add keywords to the tracker to follow how they change
