Legacy traffic refers to the traffic that has been generated over a long period of time and is usually associated with established websites or platforms. This type of traffic is often difficult to quantify and can be a combination of direct traffic, organic search traffic, and referral traffic. Other synonymous terms for legacy traffic include historical traffic, traditional traffic, established traffic, and heritage traffic. These terms refer to the same concept of traffic that has been accumulated over a period, and is generated through established sources rather than through aggressive marketing campaigns or promotions. Regardless of the term used, legacy traffic is a valuable asset for any business, as it represents a loyal and committed user base that can be tapped into for future growth.
