#3 reveals the most information.  Because 1 visit to 1 website, meh. But the patterns that emerge from watching someone’s traffic can reveal a lot.

Examples:

– multiple daily visits to the same Facebook page = the person is obsessed with someone

– repeat visits to Tumblrs featuring X type of content = the person has a fixation for X

– visits to websites detailing how to covertly do X = the person potentially has nefarious plans to execute X attack

* – that’s the cookie / tracking code that follows you around the internet, monitoring where you’re going
