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
