Referral traffic is Google's method of reporting visits that came to your site from sources outside of its search engine. When someone clicks on a hyperlink to go to a new page on a different website, Analytics tracks the click as a referral visit to the second site. The originating site is called a “referrer” because it refers traffic from one place to the next. Referral traffic is one of three statistics tracked by Google Analytics. The others are Search traffic -- visits from a search engine -- and Direct traffic to a domain.
