Referring Root Domain in processing rule should work the same as Referring Domains Report in SiteCatalyst.
The former returns values as follows:
- co.jp
- ne.jp
- google.com
As you can see, 'co.jp' and 'ne.jp' seem to be Referring "Second Level" domain. Instead, I would like to have the values as follows:
- yahoo.co.jp
- google.co.jp
- biglobe.ne.jp
- google.com
