Use the following campaign parameters to populate custom reports that include information on campaigns:
wt.mc_ev identifies the ad event type, such as
click for an ad clickthrough event.
wt.mc_ev values include
view. You can also specify custom values.
wt.mc_id associates pages with a specific campaign.
Important: Multiple IDs are not supported and no errors are logged.
If you were to specify multiple campaigns (not recommended), the campaign ID strings are processed as a single string and attribution processes will consider it to be a single campaign. For example, if you were to specify the following parameter value, only a single campaign ID would be stored.
This campaign would appear incorrectly in reports as
Campaign01;Campaign02;Campaign03. All campaign attribution, such as revenue or engagement, is applied to the single string. If the same set of campaigns is specified in a different order, it is considered to be a new separate campaign.
