The usage share of web browsers is the percentage of visitors to a group of websites A website is a collection of related web pages, images, videos or other digital assets that are addressed relative to a common Uniform Resource Locator (URL), often consisting of only the domain name, or the IP address, and the root path ('/') in an Internet Protocol-based network. A web site is hosted on at least one web server, accessible via a that use a particular web browser A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier and may be a web page, image, video, or other piece of content.

Accuracy

Measuring browser usage in the number of requests (page hits) made by each user agent A user agent is a client application implementing a network protocol used in communications within a client–server distributed computing system. The term most notably refers to applications that access the World Wide Web, but other systems, such as the Session Initiation Protocol , use the term user agent to refer to both end points of a can be misleading.

Overestimation

Not all requests are generated by a user, as a user agent can make requests at regular time intervals without user input. In this case the user's activity might be overestimated. Some examples:

Underestimation

It is also possible to underestimate the usage share by using the number of requests, for example:
