The Conversion Rate is the percentage of visitors who take an action (e.g., purchase, register) on a website. Conversion Rate (CR) is calculated by dividing the number of people who took action by the number of people who were asked to take it. Improving Conversion Rate involves A/B Testing to optimize both the website and the sales funnel. This is done by analyzing data (e.g., using Google Analytics) to determine how people are moving through a website and where they typically exit. Based on these insights, improvements can be made.
