The 'Referrer' dimension reports which URLs visitors were on when clicking through to reach your site. This dimension is useful to understand which specific URLs drive the most traffic to your site. A link must exist on the external URL and a visitor must click it in order for the dimension item to show up.
You must configure your report suite's Internal URL filters to use this dimension. Failure to configure internal URL filters can either include internal URLs or prevent external URLs from appearing.
The same report can show different results between Analysis Workspace and Data Warehouse. Analysis Workspace reports the referrer for each individual page, excluding values that match internal URL filters. Data Warehouse reports only the first referrer of the visit, and ignores internal URL filters.

- Within the Analytics interface, you must configure your report suite's Internal URL filters . Failure to configure internal URL filters can either include internal URLs or prevent external URLs from appearing.
Dimension items include URLs that visitors click through to your site. If a hit does not have any referrer data, it groups under the dimension item "Typed/Bookmarked" . This dimension item 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. The "Typed/Bookmarked" dimension item also appears for redirects that don't accommodate Analytics. See Redirects and aliases in the Technotes user guide.

When a user clicks this link and views the content that Google cached, webcache.googleusercontent.com is a typical dimension item.
- Translated pages : Google offers a robust and convenient translation service. When viewing a site using this service, it originates from translate.googleusercontent.com . This dimension item appears if the user clicks a link to return to the original content.
