A digital footprint refers to the trail of data you leave behind while using the internet. This includes everything from your social media posts to the websites you visit and the information you share online. Your digital footprint can be either active, such as when you post on social media, or passive, like when websites track your browsing habits without your explicit consent. Understanding your digital footprint is crucial for maintaining your online privacy. It can impact your reputation and the way companies target you with advertisements. Being aware of your digital footprint helps you manage your online presence and protect your personal information from potential misuse.
