Saw a great online seminar earlier this week featuring Jennifer Laycock of Search Engine Watch. You can see a recorded version of the seminar (including the PowerPoint slides) here. ...it installs webex on your computer ...but I still recommend it.
Also the free Clicktracks program is pretty sweet if your host provides log files. I haven't tried their paid stuff.
I'm loosing steam on the 30 day challenge....I'm going to try to suck up as much information as possible. But it is a time sucker!
