What Is Conversion Rate Optimization (CRO)? The 2025 Guide

CRO (Conversion Rate Optimization) is the systematic process of increasing the percentage of visitors who take a desired action—whether that's buying a product or booking a demo.

The CRO Loop

  1. Analyze: Use quantitative data (GA4) and qualitative data (Heatmaps) to find friction. (See: Guide to Heatmaps).
  2. Hypothesize: "If we remove the phone number field, conversions will increase by 5%."
  3. Test: Run an A/B test to validate your hypothesis.
  4. Repeat: CRO is never "done."

Why Traffic is Vanity

Doubling your traffic is hard. Doubling your conversion rate is often cheaper and yields the same revenue impact. (Read: Measuring SEO ROI).
