Tool Evaluation Criteria
- Data accuracy: How close are volume estimates and ranking data to reality?
- Update frequency: How often is the index refreshed?
- Integration: Does it connect with your other tools and workflows?
- API access: Can you programmatically extract data for custom reporting?
- Value overlap: Does it duplicate capabilities you already have?
Start with free tools, add paid tools as specific needs arise, and regularly evaluate whether each tool in your stack is earning its cost through actionable insights you can’t get elsewhere.
