A digital footprint is the record of an individual's online activities, interactions, and contributions, creating a trail of data on the internet. It includes social media posts, online searches, website visits, email communication, online purchases, and more. Both intentional actions and passive data collection contribute to a digital footprint. Managing and being aware of one's digital footprint is important for privacy and online reputation. Individuals can take steps to control the information they share and be mindful of their online activities.
