Google Analytics is a widely used tool to compile anonymous visitor statistics; such as how many people have visited a website, what type of technology they are using (e.g Mac or Windows), how long they spend on the site, what pages they look at etc. This information helps website owners to continuously improve site content and visitor experience.
"Like many services, Google Analytics uses first-party cookies to report on visitor interactions. These cookies are used to store non-personally identifiable information, such as what time the current visit occurred, whether the visitor has been to the site before, and what site referred the visitor to the web page. Browsers do not share first-party cookies across domains."

To provide website visitors more choice on how data is collected by Google Analytics, Google have developed the Google Analytics Opt Out Browser Add-on. This add-on communicates with Google Analytics to indicate that information about your website visits should not be sent to Google Analytics.
