What does eCommerce primarily refer to?

eCommerce primarily refers to the buying and selling of goods and services over the internet. This concept encompasses a wide range of commercial transactions conducted online, including retail sales, auction sites, and business-to-business transactions. The internet provides a platform for businesses to reach a global audience, facilitating transactions that offer convenience and efficiency for consumers.

This definition specifically highlights the digital nature of modern commerce, distinguishing it from traditional methods that involve physical storefronts or direct face-to-face interactions. While other options mention aspects of commerce, they do not capture the essence of what eCommerce entails. For example, the use of physical stores relates to traditional retail models, trade agreements focus on economic relations between countries, and mobile transactions are just one aspect of the broader eCommerce landscape. Each of these alternatives either contrasts with or falls short of addressing the comprehensive framework that eCommerce encompasses.
