Ecommerce websites can vary in size and complexity, from small online stores with a few products to large marketplaces with thousands of products and multiple vendors. They can also be built on different platforms, such as Shopify, WooCommerce, Magento, and BigCommerce.

Ecommerce websites are popular among businesses of all sizes because they offer a convenient and efficient way to sell products and services to customers worldwide, without the limitations of a physical store. Customers can browse products, compare prices, and make purchases at any time, from anywhere, using a computer or mobile device.
