I have a few sites on *nix/Apache (hosted). The webstats are handled by the free AWStats, Webalizer and Analog Stats. They're all great apps.
But I'm seeking something that will also (in addtion to the usual info) track individual visitor's movements at the site, which files they've downloaded, how long they stayed, their history, etc. Preferrably presented in a nice, easily understood way.
Of course, I'm prepared to pay a reasonable amount for this, whether I need to purchase the software or subscribe to a service hosted elsewhere.
Can someone give a suggestion? Or warn?
