MerchantWords review
A focused Amazon research suite with reverse ASIN, competitor gaps, SERP analysis, and API access.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MerchantWords is a paid keyword research and marketplace intelligence platform for Amazon sellers, brands, agencies, and developers. It combines estimated search volume with seasonality, trend, history, and depth metrics, then extends research into reverse ASIN lookup, related and complementary terms, competitor comparisons, digital-shelf keyword gaps, and Page 1 product and SERP analysis. The platform is available on the web and through an API, with data across 11 Amazon marketplaces.
Pricing is organized into four monthly plans. Silver costs $35 per month and includes 500 searches, one user, 10 collections, and single-country data. Gold costs $79 per month and raises the allowance to 1,000 searches, two users, 100 collections, and regional data. Platinum costs $149 per month with unlimited searches, three to five users, 1,000 collections, and global data. Enterprise costs $749 per month and adds unlimited searches, 20 concurrent users, 10,000 collections, and all features. The plans make usage, collaboration, collection capacity, and geographic coverage the main upgrade factors.
For research workflows, Keyword Explorer supports word-count buckets, filtering, selection, and export, while collections help organize keyword lists. Developers can access keyword, ASIN, SERP, and bulk data through REST API and MCP access, with integrations for Claude Desktop, Claude Code, Cursor, VS Code Copilot, LangChain, CrewAI, and OpenAI Actions. MerchantWords is a strong fit for Amazon-focused teams that need marketplace signals and repeatable research workflows. Teams seeking general web SEO, search-intent classification, or a free starting tier should consider a broader or more accessible alternative.
