Why Amazon Keyword Research Tools Matter
Amazon’s algorithm determines which products appear for a given search query. The algorithm weighs relevance, sales velocity, and conversion rate — but relevance starts with keywords. A dedicated tool solves three problems: Discovery — finding every relevant search term including long-tail phrases. Prioritization — sorting by volume, competition, and relevance. Competitor intelligence — revealing which keywords competitors rank for.
