Most Koreans today use Naver, which has 70 percent of the portal market, or Daum, which has 20 percent. Portal market share is based on the number of searches performed. Although Google and Yahoo are Internet search engines and portal sites that are globally competitive, they have failed to catch on in Korea. Google ranks a distant third, and Yahoo Korea closed up shop in December 2012.
When it began in 1997, Yahoo Korea established itself as a leading domestic portal site, at one time ranking first in visitor numbers. However, its market share declined drastically after 2000, until it was knocked out of the top 10 in September 2012 with a share of less than 1 percent. Korea is one of five countries, along with China, Japan, Russia and the Czech Republic, where Google has failed to dominate the Internet search market, according to a survey released by Democratic Party lawmaker Yoo Seung-hee. Google entered the domestic market in March 2001.
Google operates in 50 countries and has 82 percent of the world’s portal market. Yet it has only managed to gain a share of 3 percent in Korea, according to Nielsen KoreanClick, an Internet research and consulting firm. As of November, Google had 11.4 percent of the domestic mobile portal market compared to Naver’s 70 percent and Daum’s 13.4 percent.
