What is Web Analytics and why is it important?

I cannot find an answer online for this, so any of them could be correct. I would suggest doing some more in-depth research, as the research I did was preliminary. However, the two answers given here sound right.
Viewing in Internet Explorer on the same computer would be my best guess, since Firefox has actually come out with ways to block Google Analytics from gaining any information about sites visited via Firefox.

This is all I could find information on when I searched to see what Google Analytics would count as a new visit from Firefox. Given how good they claim it is (I don’t use Firefox so I can’t say how good it is), I don’t think anything on Firefox that has the blocker, or without the blocker completely installed, would be counted.
