Conversion Rate Optimization (CRO) refers to the systematic process of increasing the percentage of website visitors who take a desired action, such as making a purchase, signing up for a newsletter, or filling out a contact form. In the context of entrepreneurship, CRO is crucial because it directly impacts the efficiency and profitability of a business. By optimizing the conversion rate, entrepreneurs can maximize the return on investment (ROI) from their marketing efforts without necessarily increasing traffic.
