CRO, or Conversion Rate Optimization, is the process of improving a website or landing page to increase the percentage of visitors who take a desired action. This action could be making a purchase, signing up for a newsletter, or filling out a contact form. By analyzing user behavior and making data-driven changes, businesses aim to enhance user experience and boost conversions. Techniques used in CRO include A/B testing, where two versions of a page are compared to see which performs better, and user feedback collection to understand visitor preferences. Effective CRO can lead to higher revenue and improved customer satisfaction.
