What type of website is primarily designed to sell goods and services?

Commerce websites are specifically designed to facilitate the buying and selling of goods and services over the internet. These sites provide a platform for businesses to showcase their products, manage inventory, process transactions, and handle customer relationships. They often include features such as shopping carts, payment gateways, and user account management to enhance the shopping experience.

In contrast, social media websites focus on connecting users and enabling social interactions. Information websites aim to provide knowledge and resources on various topics but do not engage in direct sales. Entertainment websites primarily offer content for leisure, such as videos, games, and music, rather than focusing on commerce. Therefore, commerce websites stand out as the correct answer since their main purpose revolves around commercial activities.
