CRO (Conversion Rate Optimization)

CRO (Conversion Rate Optimization) is the systematic practice of increasing the share of visitors who take a desired action — buying, signing up, booking — through testing and refining the experience. It works through hypotheses, experiments like A/B tests, and analysis of how users actually behave, not guesswork. Because CRO lifts results from traffic you already have, it compounds the return on every other channel. A small conversion gain often beats a large spend increase on economics alone.
