AI tools excel at categorizing keywords by intent:
- Informational: "how to," "what is," "guide"
- Commercial: "best," "review," "comparison"
- Transactional: "buy," "discount," "free trial"

Focus on keywords that match your content goals and business objectives.

Maximizing Your Keyword Research Results

Track Performance Over Time
Monitor how your chosen keywords perform:
