Data are gathered by means of tracking scripts embedded in the source code of websites measured by Gemius. Thanks to the information collected by the tracking scripts, every page view can be assigned to the appropriate category, e.g. web browser – Chrome 61, or operating system – Android. Aggregated and sorted data form a ranking within one category.
Every ranking is calculated based on traffic on websites for which at least 100 page views of a particular category is registered every week.
Rankings are calculated as percentage share of views (page views and stream views).
In the rankings statistics are presented which in a current week attained the percentage value equal to or exceeding 1%.
