In short, it is your digital identity. Just like a tattoo, your digital reputation is an expression of yourself. It is formed and added to by you and others over time. Your digital tattoo includes things like websites or blogs you’ve created, tweets, blog comments, your account or screen names and everything else you’ve left on the Internet from your online activities.
Just like a real tattoo, a digital tattoo is easy to create but extremely difficult to remove. But it’s also unlike a tattoo in that it’s not always in your control, since other people have the ability to post information about you online.
There is nothing wrong with having a digital tattoo – digital tattoos are not bad or dangerous, and positive posts can actually work to enhance your reputation. Plus if there is anything negative about you, it helps to have some positive information to counterbalance it.
Being on the Internet is like being in public – anyone and everyone are watching you, and you don’t know who they are. You don’t know who is looking for you on the Internet or why. Ask yourself for a minute why someone might search for you online? It’s also incredibly difficult to erase information on the Internet simply because of the ease in which it can be transmitted – messages and pictures can be easily passed around through cutting and pasting, email, re-tweeting, embedding etc. In this way, the Internet can work as a permanent memory bank.
People also judge you by how you behave online, which can affect you later in life with things like employment (finding a job), college acceptance and your real life relationships.
