Google Analytics identifies a referring site as a website that has directed one or more visitors to the site in question. These visits originate from external links provided by the referring site and pointing to the analyzed site. On the same referring site, different pages may contain external links leading to the analyzed site. In addition to generating traffic, referring sites contribute to SEO by boosting a site’s backlink popularity. For example, currently, sites like Wikipedia or Blogspot can be sources of traffic for the definitions-marketing website.
