Conversion Rate Optimization (CRO)
Conversion rate optimization (CRO) is the practice of increasing the share of visitors who take a desired action, like buying or signing up, usually through experimentation.
What CRO means
Conversion rate optimization is the systematic process of improving how well a website turns visitors into customers, leads, or sign-ups. Instead of buying more traffic, it extracts more value from the traffic you already have.
How CRO works
A typical CRO loop is to analyze where visitors drop off, form a hypothesis about why, build a variant, and run an experiment to measure the impact. Winning changes are kept, losing ones are discarded, and the cycle repeats.
CRO vs SEO and ads
SEO and paid ads bring people to your site, while CRO determines how many of them act. Because it compounds on existing traffic, CRO is often the cheapest growth lever, which is why teams increasingly automate it with AI.
