This is your reputation on the internet (it’s an abbreviation of “net reputation”). When someone enters your name in Google, what comes up on page 1 (the most read)? The profile you have used to register on social networking sites? Interesting professional achievements, conferences, publications… anything that gets you talked about. Do not confuse your digital identity (how you present yourself online), which you can control, with your digital reputation (how you are spoken of by others), which you can’t.
