"Referrer" is a term commonly used in marketing and website analytics to describe someone who directs traffic to a website by clicking on a link or sharing it with others. There are several alternative terms that can be used to describe a referrer, including "referrer source," "traffic source," "referrer website," and "referral partner." In some cases, the term "referrer" is used specifically to describe organic traffic that comes from search engines, while the term "referral source" may be used to describe traffic that comes from social media or other sources. Regardless of which term is used, understanding the source of website traffic is an important component of digital marketing analysis and optimization.
