Keyword research remains the foundation of SEO. In 2025, free GenAI keyword tools go beyond volume data—they analyze user intent, context, and trends to suggest keywords that can bring real traffic. Marketers use these tools to uncover long-tail keywords, understand questions people ask, and optimize content that matches search intent perfectly.
