Keyword Tool Dominator vs MerchantWords (2026): which should you pick?

Pick Keyword Tool Dominator if

• Fits if you sell on Amazon, eBay or Walmart and want the words shoppers type there
• Works for anyone who would rather pay once than keep another subscription

Look elsewhere if

• Skip it if you need real monthly search volumes, as it only gives a popularity score
• Not for you if you browse in Safari or Firefox, as the dashboard needs the Chrome or Edge extension
• Tight if you buy Plus, which covers 1 of the 8 platforms with 50 searches a day; all 8 need Max
• Watch out: 30-day and 90-day access ends without renewing, and refunds stop after 7 to 30 days or heavy use
• Watch out: AI expansion and article drafts run on tokens, from 50 to 1,500 depending on plan

Pick MerchantWords if

• Fits if you write Amazon listings and want the phrases shoppers type there
• Works for checking which keywords put a rival's product on Amazon's first page

Look elsewhere if

• Not for you if you want to try before paying, as there's no free plan or trial
• Skip it if you sell on Walmart, eBay or Etsy too, as that data is only a custom report on request
• Tight if you sell in several countries, as Silver covers one; regional data needs Gold at $79
• Watch out: the whole database refreshes every 3 to 4 weeks, so figures can lag
• Pricey if you need every marketplace, at $149 a month for Platinum, or $749 for a team of up to 20
