We currently started reviewing IndexTools for website statistics. After having used webalizer (yuck), webtrends and awstats I ran into Indextools.
Basically what I found useful about it was the ability to track all my marketing campaigns , see the bounce rates of visitors, track all visitor paths down to uniques and alot more.
We have partnered with Indextools to bring THF visitors a 30 day trial, not thier standard 15 day trial. PM me after you register for the trial and I will get you upgraded.
