Online identity management (OIM) (also known as online image management, online personal branding or personal reputation management (PRM)) is a set of methods for generating a distinguished Web presence of a person on the Internet.
Online identity management also refers to identity exposure and identity disclosure, and has particularly developed in the management on online identity in social network services or online dating services.
One aspect of the online identity management process has to do with improving the quantity and quality of traffic to sites that have content related to a person. In that aspect, OIM is a part of another discipline called search engine optimization with the difference that the only keyword is the person's name, and the optimization object is not necessary a single web site; it can consider a set of completely different sites that contain positive online references. The objective in this case is to get high rankings for as many sites as possible when someone searches for a person's name.
Another aspect has to do with impression management, i.e. "the process through which people try to control the impressions other people form of them." One of the objective is in particular to increase the online reputation of the person.
Online identity management often involves participation in social media sites like Facebook, LinkedIn, Flickr, YouTube, Twitter, Myspace and other online communities and community websites, and is related to blogging and blog search engines like Technorati.
But it can also consist in more questionable practices. Hence in the case of social network services users have the possibility to buy "friends" so to increase their visibility.
