Gotcha and thank you for the diagram! Just to confirm I'm understanding correctly...
In most cases, the visit_ref_domain will always show you the domain of the "last touch" of the entire visit but the ref_domain will be the referring domain for each page.
Sorry, one more question. There are columns called va_closer_detail and va_finder_detail. I'm reading that they are variables used in the last touch dimension. How do these relate (if at all) to the visit_ref_domain and ref_domain?
Yes, I believe we are on the same page... I don't have a raw data feed in front of me to 100% confirm, but based on the names and descriptions (and what I see in the referrer data when testing an implementation) this should be what you are getting.
No worries about the questions... this is tricky stuff when you are starting out (and even when not starting out 😉 )
To be honest, I have not used those last 2 fields: va_closer_detail and va_finder_detail, but they actually seem to be tied to Marketing Channel info... I just didn't think that would come through since that is based on Classification Rules and can be changed... but maybe in this case they are sending the value through based on the current or default rule sets?
However, my best guess is that va_closer_detail would be the last touch 'Marketing Channel", and va_finder_detail would be the first touch "Marketing Channel"... both of these must be based on the "at the time of raw data export" rules set... but also, the default Attribution of Marketing Channels is 1 week
So you need to bear this in mind, that the first touch value in a 7 day span could be a completely different value than what you see in the visit data for this user... maybe 7 days ago they came via Social Media, and today they came via a Search Engine (or even directly - and directly would result in no ref_domain on the first page / visit_ref_domain for the visit)
