Conversion page
A sample conversion is logged whenever this page is viewed by a user. This is ensured through the settings specified on the Analytics -> Settings tab of the document.
In order for conversions to be logged, it is also necessary to have the Enable web analytics and Track conversions settings checked in Site Manager -> Settings -> On-line marketing -> Web analytics.
Typically, conversions will be used in more advanced scenarios to represent some type of important action, such as the downloading of a file, a product purchase etc.
