Can anyone suggest how I would I go about exporting visitor level activity by visitor, page and device?
Ex (something like...):
visitorid 1 | url | desktop | date&time
visitorid 1 | url | mobile | date&time
visitorid 2 | url | desktop | date&time
visitorid 2 | url | tablet | date&time
visitorid 3 | url | mobile | date&time
You can use Data Warehouse to export Visitor ID, URL or Page Name and Device Type with hour granularity by minimum.
If you need exact Time Stamp, you need to use Data Feed but note that it is pre-processed data and you need to calculate the metrics by yourself . Link : Calculating Metrics
Hope this helps.
Thank you, Arun!
