What is conversion rate optimization (CRO)?
Quick answer
Conversion rate optimization is the practice of increasing the percentage of visitors who take a desired action — buying, signing up, or enquiring — without needing more traffic. It uses analytics, user testing, and experiments like A/B tests to find what's stopping people and fix it, so your existing traffic earns more.
CRO starts with understanding where visitors drop off — using analytics, heatmaps, and session recordings — then testing specific changes to pages, forms, or the checkout. Because it improves results from traffic you already have, it's often more cost-effective than simply buying more visitors.
Typical wins come from clearer messaging, faster pages, simpler forms, stronger calls to action, and removing friction at checkout. The discipline is to change one thing at a time and measure the effect, rather than redesign on a hunch.
