What is a digital footprint?
Every time you use the internet — searching, clicking, posting, commenting, liking, or playing — you leave behind a trail of information called a digital footprint. Just like footprints in sand show where you have been, your digital footprint shows what you have done online.
Your digital footprint is made up of all the information you have shared or that has been collected about you online. It can include posts you have made, accounts you have created, websites you have visited, and even searches you have typed into a search engine.
Unlike footprints in sand that wash away, digital footprints can last for a very long time — sometimes years or even decades. And they can be seen by many different people: websites, companies, schools, and sometimes other people.
Two types of digital footprints: An active footprint is information you choose to share — posts, comments, sign-ups, and messages. A
passive footprint is information collected without you realizing it — like websites tracking which pages you visit or apps recording how long you use them.

Why your digital footprint matters
Your digital footprint can affect your future in real ways. Schools, employers, and colleges sometimes look at what people have posted online when making decisions. Kind, thoughtful, and positive posts build a good digital reputation. Mean, inappropriate, or hurtful posts can cause serious problems — even years later.
The best habit is to think before you post: Would I be okay if my teacher, parent, or future self saw this ten years from now? If the answer is no, do not post it.
You can also take steps to keep your footprint small and positive: use privacy settings, think before you share, and regularly review what you have posted online.
