Which of the following best defines conversion rate optimization? (Select the best answer.)

Conversion Rate Optimization (CRO) is the process of improving your website or landing page to increase the percentage of visitors who complete a desired action, such as making a purchase, filling out a form, or signing up for a newsletter. The goal is to maximize the value from existing website traffic, rather than simply attracting more visitors. Increasing the average time a user spends on your website is a metric, but not the definition of CRO itself; time on site can be a factor in conversion but isn't the primary goal. Driving a higher number of website visitors to a particular page is related to traffic generation, not optimization of the conversion rate once they arrive.
