Conversion Rate Optimization (CRO)
GLOSSARY
Definition
Conversion rate optimization is the practice of increasing the percentage of visitors who take a desired action — buying, signing up, requesting a demo. It combines A/B testing, user research, analytics, and UX design to remove friction from the conversion path.
Why it matters
CRO used to mean 'change the button color and measure.' The discipline matured into something closer to applied behavioral science. The AI angle is real but narrow: tools can generate test variants and analyze results faster, but they can't tell you why visitors aren't converting. That still requires watching session recordings and reading support tickets. The best CRO teams use AI for volume and humans for insight.
