First you need to register
your site, get the counter code, and place it on the site pages. If the counter has been installed correctly, the counter image should be fully visible when you view pages. If you have chosen a counter that displays certain data, this data should be visible as well.
Once the counter has been installed, the Summary Statistics report should contain hits and hosts data other than zero if your site has had visitors. To test how the counter works, you can view your site as a visitor.
The "Online Visitors" counter does not store statistics, meaning that its reports will not contain visitor data.
If you cannot see the counter image after correctly performing installation, this may be caused by applications filtering ad banners.
