Can someone track the websites I visit and why would they do it?
With computer privacy, someone might be interested in tracking the websites that you visit for purposes of advertising and marketing. Essentially, they track to as they want to know what you're doing online, how long you're there, what kinds of things that you do. This is your information that they may use to sell or advertise to you, or it might be information that they sell to another party. Information about you, what you do, what you like to do, all has a lot of value because information is key. So, tracking information is either used to help a manufacturer or producer gear something specifically towards you, or its just information that's collected and then sold to another party. On the really dark side of tracking your private activity, people can actually count the keystrokes that you do. Some businesses use this to make sure that their employees aren't sending personal email, aren't surfing in places that they shouldn't be, or really gauging that activity. Or, from your home somebody could in theory monitor and track the private information you put in and pick up on sequences that are logins, passwords, financial information, and credit card numbers. There are patterns to all these different types of information, and that's what they could capture and use or sell.
