MerchantWords Review: 12+ Years of Real Amazon Shopper Search Data

Keyword tools that estimate search volume from generic web data can miss what actually matters for Amazon sellers: what people type into Amazon's own search bar. MerchantWords has built its entire platform around real Amazon shopper searches, aggregating billions of them across more than two decade's worth of data collection.

What Is MerchantWords?

MerchantWords is an Amazon keyword research platform that helps sellers discover high-performing search terms, analyze competitor products, and identify market opportunities, all built on data aggregated from billions of real shopper searches across Amazon marketplaces.

Key Features

Classic Search. Core keyword volume, search trends, and seasonality data for any given search term.

ASIN Plus. Reverse lookup functionality that reveals which keywords a competitor's specific ASIN ranks for — a direct way to reverse-engineer a competitor's keyword strategy rather than guessing at it.

Product Tracker. Daily monitoring of keyword ranking positions, so sellers can see movement day-to-day rather than checking manually or waiting for a weekly report.

Keyword Multiplier. Identifies related and complementary search terms to expand a keyword list beyond the obvious seed terms.

Page 1 Products. Shows the top-ranking products for any given keyword, useful for competitive analysis and understanding what a "winning" listing looks like for that term.

Emerging Trends. Highlights brand-new, underexploited search opportunities — valuable for sellers trying to get ahead of demand before competition increases.

Bulk search. Analyze multiple keywords or ASINs simultaneously rather than one at a time.

Who MerchantWords Is For

MerchantWords serves Amazon sellers, FBA businesses, and e-commerce entrepreneurs focused on optimizing product listings, improving PPC campaign targeting, and discovering new product niches through keyword-driven market signals.

Pricing

Tiered plans start at $35/month for Pro features, with free access available for basic tools without a subscription.

Strengths and Considerations

The 12+ years of Amazon data analysis and coverage across 21 Amazon marketplaces globally is a meaningful data-depth advantage, particularly for sellers who sell internationally and need consistent keyword research methodology across regions rather than switching tools per marketplace. The "Risk-Free Guarantee" with no contracts or hidden fees lowers the commitment barrier for sellers testing the platform. MerchantWords notes its platform was recently rebuilt for improved speed and performance — worth confirming current UI/UX firsthand, since a rebuilt platform can mean either meaningful improvement or a temporary adjustment period as users relearn a new interface.
