Internet marketing, also known as digital marketing, web marketing, online marketing, or e-marketing, is the marketing of products or services over the Internet.
Internet marketing ties together creative and technical aspects of the Internet, including design, development, advertising, and sales. Internet marketing also refers to the placement of media along many different stages of the customer engagement cycle through search engine marketing (SEM), search engine optimization (SEO), banner ads on specific websites, email marketing, and Web 2.0 strategies. In 2008, The New York Times—working with comScore—published an initial estimate to quantify the user data collected by large Internet-based companies. Counting four types of interactions with company websites in addition to the hits from advertisements served from advertising networks, the authors found the potential for collecting data upward of 2,500 times on average per user per month.
