Your digital footprint is what mark you leave on the Internet or what other people will see of you on the Internet.
How will it effect my future?
You're digital footprint can have a big impact on you're future before you go to a job interview you're boss will look you're name up on the Internet to see what kind of person you are. So before you even walk in that room or say anything they already have a judgement of you if they want to hire you or not also collages are also tend to this to to see if they want you in.
