Data Limitation
Data and reports provided by this website are the properties of Nielsen Koreanclick, an internet media research & consulting service provider. The data and reports include prospective views for various industries that may have influences on upcoming businesses of related companies or their financial status. One who uses the data and reports, however, should keep it in mind that there exists various unknown and/or uncontrollable variables that may affect the outcomes of the businesses not in the same way as the data and reports exhibit.

We, Nielsen Koreanclick, offer statistical estimation for usage and behavior patterns of domestic internet users in Korea. The estimation offered may differ from the actual data due to the existence of various factors causing statistical deviation, including sampling errors. In addition, the methodologies used for our studies may result in different conclusions compared to those of complete enumeration surveys such as ‘site-centric’ or ‘browser-centric’ researches because of the differences in measuring targets(we exclude usage data at public locations such as schools, PC café and outside of Korea) and measuring standards(we only measure completed pages as valid but not requested pages)

In addition, Nielsen KoreanClick's Mobile data targets only Android OS and iOS smartphone users. Other OS smartphones and tablet PCs are excluded from the collection list, and Android OS and iOS smartphone users account for more than 99.6 percent of all smartphone users (based on the 50th Enumeration Survey in March 2019). Mobile traffic is aggregated separately from web and app traffic due to differences in measurement criteria, and the in-app browsing content used through the application is currently not measured due to technical limitations. In-App Browsing will be included in Nielsen KoreanClick's Mobile measurement list through future technical supplementation.
