Attracting visitors to your website is only half the battle—getting them to take action is where the real challenge lies. Whether you want users to buy a product, sign up for a newsletter, or fill out a form, optimizing your conversion rate is essential for maximizing sales and revenue.
Conversion Rate Optimization (CRO) is the process of analyzing, testing, and improving elements on your website to increase the percentage of visitors who take a desired action. With the global eCommerce conversion rate averaging only 2.35%, businesses that don’t prioritize CRO are leaving money on the table.
