Before diving into Conversion Rate Optimization (CRO), it's important to understand the concept of conversion rate. This rate reflects the percentage of website visitors who take a specific action, such as making a purchase or subscribing to a newsletter. For example, if your site receives 1,000 visitors and 50 make a purchase, your conversion rate is 5%. A higher conversion rate indicates that your site effectively encourages users to take desired actions. CRO focuses on improving this rate by optimizing the user experience and using data-driven strategies to maximize the value of your existing traffic, leading to higher revenue and reduced acquisition costs.
