Reputation management, is the process of tracking an entity’s actions and other entities’ opinions about those actions; reporting on those actions and opinions; and reacting to that report creating a feedback loop. All entities involved are generally people, but that need not always be the case. Other examples of entities include animals, businesses, or even locations or materials. The tracking and reporting may range from word-of-mouth to statistical analysis of thousands of data points
Reputation management has come into wide use with the advent of widespread computing. This is evidenced by a front page story in the Washington Post.  featuring several online reputation management firms. Reputation management systems use various predefined criteria for processing complex data to report reputation. However, these systems only facilitate and automate the process of determining trustworthiness.
This process is central to all kinds of human interaction, including interpersonal relationships, international diplomacy, stock markets, communication through marketing and public relations and sports. Reputation management is also a professional communications practice – a specialization within the public relations industry. Reputation management ensures that the information about an individual, business or organization is accessible to the public online as well as through traditional outlets and is accurate, up-to-date and authentic
The classic example of reputation management is the small town. Population is small and interactions between members frequent; most interactions are face-to-face and positively identified — that is, there is no question who said or did what. Reputation accrues not only throughout one’s lifetime, but is passed down to one’s offspring; one’s individual reputation depends both on one’s own actions and one’s inherited reputation
The large metropolitan area is at the other end of the spectrum from the small rural town. Community members come and go daily, and most members are only personally acquainted with a small fraction of the whole. Implicit reputation management continues to work within subcommunities, but for the city as a whole, it cannot.
Big cities have developed a large array of formal reputation management methods. Some apply only to subcommunities, such as, say, an association of local dentists. There are four methods (among others) which apply quite generally to the entire population: elections, appointments, the criminal justice system, and racial or ethnic prejudice.
eBay is an online marketplace, a forum for the exchange of goods. The feedback system on eBay asks each user to post his opinion (positive or negative) on the person with whom he transacted. Every place a user’s system handle is displayed, his feedback is displayed with it. Since having primarily positive feedback will improve a user’s reputation and therefore make other users more comfortable in dealing with him, users are encouraged to behave in acceptable ways—that is, by dealing squarely with other users, both as buyers and as sellers
Everything2 is a general knowledge base. E2 manages both user and article reputation strongly; one might say it is central to the project’s paradigm. Users submit articles, called writeups that are published immediately. For each article, each user may cast one vote, positive or negative. Voting is anonymous and each vote cast is final.
The article keeps track of its total of positive and negative votes (and the resulting score), all of which can be seen by the submitting user and any user who has already cast their vote on that particular article. Articles with strong positive scores may also be featured on the site’s main page, propelling them to even higher scores. Articles with low or negative scores are deleted, hopefully to make way for better articles
