Original referring domain
The 'Original referring domain' dimension reports the first referring domain that a visitor clicked through to reach your site. Once it is set, it contains the same value for the entire lifetime of that visitor ID. This dimension is useful to understand which third-party sites originally drive traffic to your site.
Populate this dimension with data
This dimension requires configuration in both the Analytics interface and your implementation.
- Within the Analytics interface, you must configure your report suite's Internal URL filters . Failure to configure internal URL filters can either include internal domains or prevent external domains from appearing.
Adobe persists original referring domain for a visitor's lifetime. If a visitor leaves and clicks through a link on a different domain at any time, the new value is not recorded. If you want to see new values, see Referring domain .
Dimension values include domains that visitors click through to your site. If a hit does not have any referrer data (either set or persisted), it groups under the dimension value "None" . This dimension value means that there was no referrer value, such as if the visitor manually typed the browser address into the address bar, or clicked a bookmark.
