Usage share, in web browser statistics, is the percentage of visitors to a group of web sites that use a particular browser. For example, when it is said that Internet Explorer has 85% usage share, it means that Internet Explorer is used by 85% of visitors that visit a given set of sites. Typically, the user agent string is used to identify which browser a visitor is using.
