What is ranking?
gemiusRanking CZ is designed to serve as a source of accessible knowledge on the Czech internet for those interested in being up-to-date on its development and the prevailing trends. The web site features, among others, popularity ratings for:
- web browsers,
- operating systems,
- mobile devices,
- Flash Player versions,
- screen resolution,
- screen color settings,
- countries from which internet users visit Czech web sites,
- regions from which internet users visit Czech web sites,
- cookie files acceptance rate.
The data published on gemiusRanking CZ is obtained through the gemiusTraffic research project conducted by Gemius SA. The gemiusTraffic study provides information on internet users' web site behaviour and the technical characteristics of their computers. The data is gathered with the use of counting scripts, which are embedded in the code of sites included in the study.
The data comes partly from the NetMonitor project carried out in cooperation with Mediaresearch on behalf of SPIR.
In April 2003, gemiusTraffic was awarded the Internactive Advertising Bureau Polska (IAB Polska) certificate.
Apart from the Czech Republic, gemiusTraffic is conducted in many other Central and Eastern European countries (Estonia, Slovakia, Lithuania, Latvia, Poland, Ukraine, Croatia, Bulgaria, Slovenia, Bosnia-Herzegovina, Russia and Hungary), as well as Austria, Denmark and Israel.
