E-commerce, short for electronic commerce, is the buying and selling of goods and services over the internet. It has transformed the way businesses and consumers interact, providing an accessible platform for transactions anytime and anywhere. E-commerce platforms enable users to browse products, compare prices, and make secure payments, all from the convenience of their own devices. These platforms offer a range of services, from retail shopping to online auctions, digital goods, and subscription services. The key to a successful e-commerce business is a seamless user experience, secure payment gateways, fast delivery options, and customer service that builds trust and loyalty. As mobile shopping and social commerce rise, e-commerce continues to expand, creating opportunities for businesses of all sizes to reach global markets.
