Conversion Rate Optimization (CRO)

Definition

The practice of systematically improving the percentage of visitors who complete a desired action. It's where you obsess over pixels and sentences until your users finally comply.

Example Usage

We hired a CRO specialist, and after 47 A/B tests, we improved our conversion rate by 0.3%—small wins.

Origin

Web analytics and digital marketing, 2000s

Fun Fact

Most A/B tests show no statistically significant difference, but marketers run them anyway because 'we might get lucky.'
