Thanks for the comments, I have returned to GA-4 and I am plowing on trying to make some sense of it.
In the concrete documentation there is a section “How To Add Google Analytics To Your Website - The easy way” published on Oct 9, 2020. It gives the code snippet that is pasted into the backend
Dashboard → System & Settings → SEO & Statistics ->Tracking Codes
This code refers to the old type of Google analytics tag, where as GA-4 appears to have measurement IDs and stream IDs (I am still not sure which is which.)
It would very nice if this part of the documentation could be updated for new GA-4 setup.
Also I noticed another posting (posted yesterday) over in the Using Concrete category entitled ’ List of Default Cookies and their purpose for Concrete CMS
I did not know the cookies listed in this post existed so this is another ting I need to try and understand.
I know all this is part of a huge topic which probably needs very significant knowledge to even begin to understand, is there any more information / tutorials available on this topic ??
