What is a custom event?
Custom events let you define the success type that you want to track.
Although similar to predefined events, custom events let you define your own success metric. For example, if you have a newsletter, your success event could be Registration . Clearly, Registration is not part of the predefined events. By using a custom event, you can track the number of visitors who register for your newsletter. Custom events follow the standard syntax shown below.
The code above shows how to assign an event to the events variable. If you do not modify the event name in the interface, event3 would display in the interface.
By default, success events are configured as counter events. Counter events count the number of times a success event is set. Some success event uses require an event be incremented by a custom amount. These events can be set either as numeric events or currency events. You can change the event type in Admin Console.
