Which term best describes the business activity that occurs when website visitors buy products or services from you online?

E-commerce (electronic commerce) specifically refers to the buying and selling of goods or services using the internet, and the transfer of money and data to execute these transactions. This accurately describes website visitors purchasing products or services online. Display advertising involves placing visual ads on websites, which is a marketing method, not the transaction itself. Search engine marketing (SEM) focuses on increasing website visibility in search engine results pages, primarily through paid advertising, which is also a marketing activity, not the online sales transaction.
