A digital footprint is a record of everything posted online about an individual, including what they post themselves, photos others post of them, and information posted by friends and family. This footprint can impact things like job applications, school admission, and what people think of an individual, both positively and negatively. To manage their footprint, people should be careful about what they post online, the websites they join, forms they fill out, who they give information to, and photos they post.
