Definition
Conversion Rate Optimization (CRO) is the systematic practice of increasing the percentage of visitors who take a desired action — sign up, book a demo, buy — through research, testing, and improvements to UX, messaging, and flow. It's grounded in hypotheses and experiments, not guesswork.
Why it matters
CRO compounds the value of every visitor you already have. A higher conversion rate lowers effective CAC and makes every channel more efficient without spending a cent more on traffic.
