What is referral traffic?
Referral traffic is defined as website hits that you get through other sites, in other words, users who come to your page through other websites without a google search. When visitors arrive on your site in this way, Google tracks the website traffic as referral data. This information can be collected in the form of UTM codes which tell website managers exactly how visitors reached your website, revealing the referral sources.
The foundation of all referral traffic is based on backlinks that are hosted on other sites and drive web traffic to your site without necessarily having anything to do with search traffic, which is more relevant to organic traffic; bookmarks and direct hits which are considered direct traffic; or algorithm performance to do with highly effective search engine optimization strategies. Referral traffic is important because it sends high-quality visitors to your site, bringing the potential to increase conversion rates. While referral traffic is not inherently based in SEO, it will help to boost your optimization and algorithm performance.
