Understanding tracking issues
The campaign was sent but the tracking does not work normally or is classified as an unknown source: "referral / s3s-main.net".
Before starting a deep investigation, you have to check the first basic configuration related to:
UTM tags configuration at the campaign design level
UTM tags, especially during redirects
Installing the Google Analytics tracking code on the landing page
When conducting the investigation, there are two possible scenarios:
The campaign generating the tracking problem is not identified: in this case, go to Chapter 1.
The campaign generating the problem is identified: the problem is isolated in the campaign settings and in this case, go to Chapter 2.
