Bravenet.com - Free Web Tools for Webmasters - besides all of the other tools and services they provide free, Bravenet offers one of the best free counters. Yes, you can find other free counters, but their sites go down often - leaving your site hanging instead of uploading quickly. And, Bravenet's counters come with free stats like where your visitors came from, what kind of browswers and monitor sizes are used most (so you can make sure your site can be viewed properly), hit counts for six months in one view, the busiest day of the week and hour of the day, view an entire week or month to see trends, and more.

StatCounter - You can ger a free yet reliable invisible web tracker, highly configurable hit counter, and real-time detailed web stats. The stats are nice, and the counter is the most accurate we've found ever!

RealTracker Free - gives you 30 real-time "news-you-can-use" statistical tools to analyze your traffic, including your visitors' browser types and platforms. More true features than any other free hit counter worldwide. RealTracker Free also offers an optional polling feature. Invite visitors to leave their opinions about your homepage site and its contents.

eXTReMe Tracking - One of the few counter/tracking systems we like. This one tracks unique visitors, hits, reloads, etc.

Add Free Stats - provides to Webmasters highly detailed free statistics on their site visitors.
