Answer
Conversion rate optimization (CRO) success is measured beyond conversion rate using metrics like average order value, customer lifetime value, retention rate, and cost per acquisition. These show whether improvements lead to more valuable customers, not just more conversions.
Teams also track secondary metrics such as time on site, pages per session, and support ticket volume to detect unintended consequences. For example, a higher signup rate with lower activation suggests onboarding issues. Revenue per visitor and return on ad spend reflect overall business impact. Qualitative feedback helps assess user satisfaction and brand perception.
