This appliation has been tested with ASP.NET 3.5 and Sitefinity 3.6 or 3.7.
This is a custom control for adding Google Analytics to any Sitefinity page or template. This control allows for a content user to set the Google Analytics account information and to disable tracking for a page or template.
The source code is avalible as well as precompiled dll. The dll is fully can be uploaded to Sitefinity via the "Upload a Control" link within the "Add Controls" toolbox in the Sitefinity Admin.
The solution can be compiled for ASP.NET 2.0 but I have yet to test this application with older versions of Sitefinity. The control can also be used outside of Sitefinity as a standalone ASP.NET user control for Google Analytics integration.
