Internet marketing, also referred to as Online Marketing, is Marketing that uses the Internet. The Internet has brought many unique benefits to marketing that include very low costs in distributing information and media to a global audience.

Internet marketing is associated with several business models. The main models include business-to-business (B2B) and business-to-consumer (B2C). B2B consists of companies doing business with each other, whereas B2C involves selling directly to the end consumer.

Some of the benefits associated with Internet marketing include the availability of information. Consumers can log onto the Internet and learn about products, as well as purchase them, at any hour. Companies that use Internet marketing can also save money because of a reduced need for a sales force. Overall, Internet marketing can help expand from a local market to both national and international market places. And, in a way, it levels the playing field for big and small players. Unlike traditional marketing media (like print, radio and TV), entry into the realm of Internet marketing can be a lot less expensive.

Furthermore, since exposure, response and overall efficiency of digital media is much easier to track than that of traditional "offline" media, Internet marketing offers a greater sense of accountability for advertisers.
