I thought "active" meant people visiting other sites? If you have a Facebook like button on your website and 100 users "visited" it, that would be counted as 100 active users as FB actively tracks anywhere you go with FB cookies.

If that is indeed true, then Google Analytics is the most visited site in the world, since every website out there has it installed.
