Which tool should I use for AEO?
Start with the Question Keyword Tool for ask-intent keywords. Pair it with comparison and preposition research when you need decision-stage language for AI answers and featured results.
Amazon Keyword Tool vs Product Keyword Tool?
Use Amazon for full marketplace/department seller workflows. Use Product when you want buyer-intent product phrasing focused research (also Amazon-powered).
