Internet marketing, also known as digital marketing, web marketing, online marketing, search marketing or e-marketing, is the marketing (generally promotion) of products or services over the Internet.

Internet marketing is considered to be broad in scope[1] because it not only refers to marketing on the Internet, but also includes marketing done via e-mail and wireless media.[2] Digital customer data and electronic customer relationship management (ECRM) systems are also often grouped together under internet marketing.[3]
