I always have a hard time explaining what "Instances" is when talking Referring Domains - and why this numbers adds up to more than the Total Visits count. Please make "Visits" available as a metric for Referring Domains.
We requested visits to be available for all reports
and specifically as it relates to Referrers here
Excellent. I will promote your general suggestion on Visits as a metric.
By the time the visits metric is available for all the variables, you can consider using ' Unified Sources DB Vista Rule ' which - as its name suggests - combines the 4 traffic sources namely campaigns, natural search, referrers and Direct (none) to show them in a single eVar.
You can get in touch with your account manager to get the same.
