What does 'Referral Tracking' mean?

Referral tracking entails gathering information throughout the entire referral process, from a customer registering to become a referrer to them sharing a referral link or code with a friend, to that friend following that link or code to become a customer, or taking any other action that is valuable to you, such as downloading an app — and everything in between. Monitoring cookies is one of the most prevalent (and accurate) methods of tracking referrals. In practice, this implies that these cookies are usually utilized in conjunction with a one-of-a-kind sharing link. In other words, when a referrer signs up for your referral program, a unique URL is established.
