Conversion Rate Optimization (CRO) is the process of improving a website or landing page to increase the percentage of visitors who take a desired action, such as making a purchase or signing up for a newsletter. By analyzing user behavior and making data-driven changes, businesses can enhance their online performance and achieve better results. CRO involves various techniques, including A/B testing, user feedback, and optimizing design elements like buttons and forms. Tools like Google Analytics and Hotjar help track user interactions, allowing marketers to identify areas for improvement. Ultimately, effective CRO leads to higher sales and better customer engagement.
