Referral traffic is a channel through which visitors come to your website from other sites, distinct from organic, paid, or direct traffic. In Google Analytics 4 (GA4), you can analyze this data to identify which specific referral sites are driving traffic to your site. Typically, referral traffic includes visitors who click on unpaid links from other websites, such as review platforms like G2 or Capterra, blogs, news articles, or partner websites. This type of traffic can be valuable as it often comes from sources that already have a level of credibility and relevance to your target audience. By monitoring and optimizing referral traffic, businesses can enhance their online presence and attract more qualified visitors who are likely to engage with their content and offerings.
