Grasping the conversion rate concept is essential before delving into CRO. This metric indicates the percentage of visitors who take specific actions, like making purchases. For instance, if your website has 1,000 visitors and 50 of them buy something, your conversion rate is 5%. A higher rate shows that your site effectively encourages user actions. CRO aims to enhance this metric by optimizing user experience and employing data-driven techniques to maximize traffic value, ultimately increasing revenue and lowering acquisition costs.
