MOBILE: How do you track mobile devices?We track over 10 billion page views per month across the StatCounter network of over 2 million websites. We analyze every page view in order to gather as much information as possible. With each page view a useragent string is sent which allows us to determine the the browser and operating system used and also to establish if the page view came from a mobile device. In this way we determine the usage of mobile devices, browsers and operating systems.
