Statcounter.com: A User's Review.
After having experienced almost all of the traffic analysis
services available on the internet, Statcounter.com is
undeniably the best traffic analysis service. One of the best
things about Statcounter.com is that they offer a free service
package. No strings, it really is free. Another great thing is
the amount of detail that the counter produces about a website
visitor. The only possible down side of the free service is the
log size. All in all, Statcounter.com is a must have for any
website.
