Google Analytics has a number of predefined segments, including:

  • Visitor type (new and returning)

  • Geolocation

  • Language

  • Browser type

  • Computer operating system

In addition to the default segments, you can configure Google Analytics to use a custom segment. This means traffic can be divided into various groups, using a characteristic defined by you, the site owner.

Creating a custom segment involves adding an additional Google Analytics tracking cookie to the user's computer. The cookie, named __utmv, is created using a JavaScript function named __utmSetVar().

__utmSetVar() can be added to a web page anywhere JavaScript can be added. This means that __utmSetVar() can be placed in many HTML attributes such as:

  • onLoad

  • onChange

  • onSubmit

The value passed into the function will be stored in the __utmv cookie. When Google Analytics processes your profile data, it creates a field named User Defined Value and populates it with the value in the __utmv cookie.
