What this dot point is asking

This outcome is about the lasting trail you leave online and how to behave well toward others. You should be able to explain what a digital footprint is and why it is hard to remove, manage your online reputation, and apply good netiquette (polite, sensible online behaviour) when communicating. This rounds off digital citizenship by focusing on your reputation and your treatment of others. In the written paper you explain the footprint, why it lasts, and netiquette rules.

The answer

What a digital footprint is

A digital footprint is the trail of information you leave online. It is made up of your posts, comments, photos, likes, the accounts you use and the sites you visit. Over time this builds into a record of what you have said and done online. Some of it you create on purpose (a post), and some is collected about you (sites you use).

Why it is hard to remove

Once something is online, it is hard to take back, because:

  • Other people can copy, screenshot, share or save it.
  • Deleting your own copy does not remove the copies others hold.
  • Old posts can resurface long after you forgot them.

So your footprint can last far longer than you expect, which is why you should think before you post.

Managing your online reputation

Your footprint shapes how others see you. Schools, universities and employers may look people up online, and old or careless posts can give a bad impression and affect a place or a job. To manage your reputation:

  • Think before posting: would you be happy for a teacher or future employer to see it?
  • Keep private accounts private and review your privacy settings.
  • Build a positive footprint by sharing helpful, respectful content; a good footprint can help you.

Good netiquette

Netiquette means polite, sensible behaviour when communicating online. Good rules include:

  • Be polite and respectful. Do not write anything you would not say to someone's face.
  • Do not type in all capitals, which reads as shouting.
  • Think before you post. Do not spread rumours or share others' private information.
  • Stay on topic and be patient and forgiving of small mistakes.

Netiquette matters because online you cannot see a person's tone, face or body language, so messages are easily misread. Being clear and respectful keeps communication friendly and protects your relationships and reputation.

Examples in context

Example 1. A job application years later. An employer searches for a candidate and finds old public posts. A student who built a thoughtful, respectful footprint makes a good impression, while careless posts from years earlier could have cost someone the job, showing how long a footprint lasts.

Example 2. A misunderstood message. A short, blunt message is read as rude because there is no tone of voice online. A student who uses good netiquette adds a friendly word and avoids capitals, so the meaning is clear and the conversation stays positive.

Try this

  • Cue. Explain what a digital footprint is and why it is hard to remove. (It is the trail of your posts, comments, photos and online activity; it is hard to remove because others can copy and share it, so deleting your copy does not erase the rest, and old posts can resurface.)

  • Cue. State four rules of good netiquette. (Be polite and respectful, do not type in all capitals, think before you post and do not share others' private information, and stay on topic while being patient with small mistakes.)

  • Cue. Explain why netiquette matters online. (Online you cannot see a person's tone, face or body language, so messages are easily misread; respectful, clear communication keeps things friendly and protects your reputation and relationships.)

A digital footprint is the trail of information you leave online through your posts, comments, photos, likes and the sites you use. It builds up over time and shows what you have said and done online.

It is hard to remove because once something is posted, others can copy, screenshot, share or save it, so deleting your own copy does not remove all the copies, and old posts can resurface.

One future effect: a school, university or employer might look you up online, and old or careless posts could give a bad impression and affect a place or a job; a positive footprint can help instead.

What markers reward: a digital footprint as the lasting trail of your online activity, the reason it is hard to remove (copies and sharing), and a realistic future effect such as schools or employers checking it.

Original4 marksState four rules of good netiquette for communicating online, and explain why netiquette matters.
Show worked answer →

Four netiquette rules, for example:

  1. Be polite and respectful, and do not write anything you would not say to someone's face.
  2. Do not type in all capitals, because it reads as shouting.
  3. Think before you post, and do not spread rumours or share others' private information.
  4. Stay on topic, and be patient and forgiving of small mistakes.

Why it matters: online you cannot see tone, face or body language, so messages are easily misread; good netiquette keeps communication clear, respectful and friendly, and protects your reputation and relationships.

What markers reward: four genuine netiquette rules and a clear reason such as the lack of tone online making respect and care important.
