I have realized that from March 2 till present, there has been a spike in Visits from 'Unspecified' under the Tracking Code metric. Before this, Visits were attributed to their respective Tracking Codes with only a handful under 'Unspecified'. This jump from March 2 is tremendous and our Tracking Codes are not receiving the number of Visits that we ought to be. This is happening globally under Paid Search, does anyone have an explanation for this issue?
If unspecified in tracking code is increasing that mean s.campaign() variable is not firing. I will suggest to please check the implementation if s.campaign() variable is firing on the pages it is expected.
