Methodology
Nielsen KoreanClick continuously measures the Internet usage of panels and processes the vast amount of data collected based on statistical theory.

In order to measure the behavior of digital audiences that is more accurate and reliable, the company collects the usage status of PCs and Android mobile devices through its own ODM (On Device Meter: software or application that collects the usage status of devices) by recursing sample panels that are representative of the Internet-enabled population in Korea. We also collect and measure iOS mobile devices by capturing network traffic data within limited technology under Apple policy. Web, applications, and other data collected in real time through a collection program or solution are sent through the collecting server, and the data collected is approximated to the population through a statistical process and published weekly and monthly.
