TinyCount is a free, safe, and anonymous counter. Use it on your web page or blog, and it will show you how many people have visited your site. Use it on an ad (works with Craigslist™), and see how many people have viewed your ad. No personal information is gathered about either the person who posts the ad or the people who look at it.
Just paste the following one line of code into your web page or ad:
