Klout is an application for measuring how influential a person on twitter. It gives a score in range of 1-100 to a twitter user. You can search for user specific klout scores by typing in a twitter id. Type in a topic to get a list of 14 people who are most influential on that topic. Type in a list name to get who is influencing that list the most. It also tells what most influencing people are talkign about right now in Hot Trends. Klout score for an individual is divided into four categories Causal, Climber, Connector and Persona in ascending order of priority. The klout graph is based upon two variables with audience as the x-axis and influence as the y-axis.

The Klout Score ranges from 1-100 and represents a person’s overall influence. Klout uses semantic analysis to determine what a person talks about and then measures how influential they are on that topic.

This Klout score is calculated by the formula:
