Can anyone point me to a good Web site statistics tool? I've used the various free options out there, but they're not terribly impressive. Here's what I need it to do:
1. It should be able to filter out referrer spam from a hostname list that I specify.
2. It should do a reasonably solid job at Web analytics -- e.g., it should be able to tell a robot from a recurring user.
3. It should be free.
Any thoughts?
