Why is the {widget_id} Macro for Traffic Source Tracking not Transferred?

Click on the "Sites" icon, which is next to your chosen campaign. 

Then, go to the "Publishers Efficiency" interface. 

When the site sub-source is not defined, the value “not set” is displayed. 

* not set * is a standard value in similar Google and Yandex reports. 

Possible reasons for this “not set” value:

1. The {widget_id} macro has been changed or removed from the ad link during the transfer itself.
2. The URL uses a redirect, where the {widget_id} macro is not transferred.
3. The required {widget_id} macro is missing in manually tagged URLs.

If you have any questions, please contact your personal manager.
