What MerchantWords is
MerchantWords is an Amazon keyword research service for sellers and e-commerce teams. Classic Search provides estimated monthly search volume, 12-month seasonality trends, related keywords, and keyword depth and strength across Amazon marketplaces. ASIN Plus finds keywords a product ranks for from its ASIN, while Product Tracker follows Amazon keyword rankings daily. Other tools include Collections, Emerging Trends, Keyword Explorer, Keyword Multiplier, Page 1 Products, and Bulk Search. Collections can be exported as CSV files for listings and ad campaigns. MerchantWords says its keyword data comes from Amazon’s autocomplete search bar; its volume and keyword figures are estimates, not guaranteed to be absolutely accurate. The service offers REST and MCP data access, with its MCP page listing Claude Desktop, Claude Code, Cursor, VS Code Copilot, and compatible agent frameworks. It is available on the web and through an API. A free API demo provides real data for fixed demo terms without an account. Paid plans start at $35/mo; Silver lists 500 searches and Gold 1,000, while Platinum and Enterprise list unlimited searches.
