Pro Tips
- *Map your questions to data types first - stack detection, traffic models, backlinks, or field performance - then choose one core tool per data type.
- *Automate pulls with an API or scheduled exports so weekly competitor and performance reports are reproducible and diffable in Git.
- *Triangulate traffic estimates across two sources for small sites to reduce model bias before committing roadmap changes.
- *Wire CrUX or RUM data into your BI layer and annotate releases, so you can attribute performance shifts to specific commits.
- *Start with month-to-month plans and validate KPI lift within 2 sprints before scaling licenses or API credits.
