Impression Pixel Tracking Question
We're looking at improving our impression tracking in AAM and the page Capturing Campaign Impression Data via Pixel Calls looks to be very helpful.
Unfortunately, it isn't clear what Signals would be passed to AAM by these pixels so that we can create our Traits appropriately.
At a guess, we'd set up rule-based traits looking at the variables like d_adgroup, but we may be wrong. We also don't have a simple way to test, so thought I'd ask here first. A search did not reveal anything obvious to me either, unfortunately.
Suggestions?
