CRO (Conversion Rate Optimization) Skill
Purpose
Provides patterns for understanding user behavior and optimizing conversion funnels beyond basic A/B testing. Combines quantitative analytics with qualitative user insights to systematically improve conversion rates across the entire customer journey.
Core Rules
- Measure before optimizing — Understand current behavior first
- Qualitative + Quantitative — Numbers + user feedback
- Funnel thinking — Optimize the whole journey, not just CTAs
- Privacy first — Anonymize data, respect consent
- Continuous process — CRO is ongoing, not one-time
- Track user intent — Tag sessions by user type and behavior
- Mobile matters — Test on real devices, not just desktop
- Context over clicks — Understand why users behave, not just what they do
- Form friction kills — Monitor field-level analytics
- Iterate systematically — Weekly review cycles, documented insights
