Target Marketing is about relevancy. People want information on what is relevant to them therefore, in order to get only relevant information, they will divulge information about themselves. Social media profile pages; tagging and bookmarking enable them to indicate their likes, dislikes and areas of interest. This in turn makes it easier to target people who will be interested in your product or service.

Target Marketing is not about reaching millions of people, some of whom might be interested; it is about reaching fewer people, all of whom will be interested.
