The term "digital footprint" refers to the trail of data that individuals leave behind while interacting online, through activities such as visiting websites, posting on social media, or making online purchases. It encompasses both passive footprints (automatically collected data) and active footprints (intentionally shared information). Understanding one’s digital footprint is crucial, as it can impact personal privacy, reputation, and even job prospects. Organizations increasingly monitor digital footprints for marketing insights, emphasizing the importance of maintaining a positive online presence.
