What the Hell is...Contextual Marketing?

Google AdSense is the most popular form of contextual marketing. A search engine bot, known as Mediabot, indexes the material on a website and determines which advertisements submitted to Google are a match. Search engines, including Yahoo! and Microsoft, display advertisements on search results pages. Those advertisements are selected based on the key words that a person enters into the search engine.

The idea of contextual marketing has been controversial because critics claim it represents an invasion of privacy. In 1999, when the search marketing company DoubleClick (now owned by Google) attempted to use the information it had collected online about consumers to create targeted promotions offline, the corporation was taken to court over its privacy policies. Public reaction led online marketers to focus on delivering marketing messages that drive responses without being intrusive.

Origin: Contextual marketing is based on the idea of personal profiling, where information about web surfers is collected via cookies. In 1995, permanent cookie technology was invented, which allowed servers to send packets of information to web browsers, and vice versa, in order to track the websites visited by the person at the computer.
