Which web analytics tool?

When analyzing a new website, it is useful to know what information is already being gathered (if any). For a quick read on which analytics package is in use on any particular site, try the Vendor Discovery and Profiling Tool at Eric Peterson’s web site Web Analytics Demystified.  Visit the link, then enter the URL for the website you want to check out. This tool does a pretty good job of detecting when multiple tracking ‘bugs’ are on a site.
