They're making money -- lots of money -- with it. Companies can collect data on every interaction you have with a website. That includes anything you click on and any information you input when you fill out a form. They can even look for keywords in your online profile or email, and, in some cases, they can access the information of people in your network. Companies aren't supposed to use data to personally identify individual users, but the technology they use to tailor ads to your interests can feel awfully personal.

Companies aggregate data to build composite profiles of people's habits, preferences, and purchases, which is valuable information for marketers. Next time you or your kid wants to register for a free site, remember that the price you pay for admission is your data. — Common Sense Media
