A digital footprint is the trail you leave online. This happens when you post, comment, text, etc. the things you post online are saved even if you delete the info, the info can be shared, copied, and searched. It is important to have a positive digital footprint because friends, parents, college admission officers, and future employers can see this information, and this can impact what they think of you. To make sure you have a good digital footprint you should always think twice before you post.
