Ecommerce website development is the process of creating and designing an ecommerce website where customers can buy products online. Because ecommerce websites are so popular with customers, creating one can help you increase conversions and revenue for your company. An ecommerce web developer's primary responsibility is to bring a website's design prototype to life and make it function as a website. In other words, web development entails making a website's design function properly. A web developer, for example, would ensure that all navigational buttons, contact forms, calls to action (CTAs), and hyperlinks function properly.
