# Campaign Event Parameter

#### WT.mc_ev

`WT.mc_ev=EventType` This parameter identifies an ad event type.

Webtrends Analytics and Visitor Data Mart recognize the following value: `WT.mc_ev=click` identifies an ad clickthrough event.

          Webtrends Analytics Considerations

          

Webtrends Analytics does not currently provide preconfigured custom reports that use the click value. However, you can also specify a custom value to identify a custom event type, create a custom report filter based on this value, and apply it to a custom report.
