Conversion Rate Optimization (CRO)
The systematic process of increasing the percentage of visitors who take a desired action on your website.
Why It Matters
CRO extracts more revenue from existing traffic, delivering higher ROI than acquiring new visitors.
How It Works
You analyze user behavior through heatmaps, session recordings, and funnel analytics to identify conversion barriers. Then you form hypotheses, design test variants, run A/B tests, and implement winners. Continuous testing compounds gains over time.
Real-World Example
An e-commerce site increases checkout conversions from 2.1% to 3.4% through a series of CRO tests, adding $500K in annual revenue.
Common Mistakes
Making changes based on opinion instead of data and testing
Ending tests too early without reaching statistical significance
