Understanding CRO ROI

Why Calculate CRO ROI?

Conversion rate optimization can have a massive impact on revenue. Even a small improvement in conversion rate can translate to significant revenue increases, especially for high-traffic sites.

Realistic Improvement Expectations

Most CRO improvements range from 10-30% increases. However, some tests can achieve 50%+ improvements. Use A/B testing to validate improvements before implementing site-wide.
