Answer
Conversion rate optimization (CRO) is the systematic process of increasing the percentage of website visitors who complete a desired goal, such as making a purchase or submitting a form. It uses data analysis, user research, and A/B testing to identify and fix barriers in the user journey, which improves marketing ROI without increasing traffic.
CRO combines quantitative data from analytics tools with qualitative insights from user testing to prioritize changes. Common tactics include improving page load speed, simplifying forms, clarifying calls to action, and personalizing content. The process is iterative, with each test building on previous results to steadily improve performance over time.
