The Referrer Dimension
The Referrer dimension allows analysis on multiple levels. Information obtained from the domain name of the referrer can be used in high-level country/domain type reports. If the referrer URL is recognized as belonging to a search engine, then the URL can be parsed to obtain the keywords used in the search. (The Search Dimension holds these search keywords, which can give insight into what users are looking for when they come to the site.)
This chapter contains the following topics:
