Implementing Google Ad Manager 1x1 Ad tracking tags

We are using Google Ad Manager (Small Business) and have successfully handled basic functions. A major advertiser wishes to implement tracking tags through GAM for some ads that we are currently not serving in the conventional online (or interstitial) format -- for our weekly eletters and magazine publication, and has provided us with the 1x1 ad tags.

If you understand this process and can help us set up the tagging/tracking process, you will have fulfilled the task. Will provide the GAM worksheet describing the tags to selected contractor. Can provide GAM Small Business account details and relevant eletter access to contractor capable of doing the job. Contractor may need to provide instructions for our in-house designer to do certain tasks that cannot be handled remotely.
