China is home to the world’s most socially active online population, says L2 in its Digital IQ Index report on China luxury brands. Ninety-five percent of online users in China’s tier one, two, and three cities are registered on at least one social media site, while 80% use social media to learn about brands, and 40% have either read or posted a product review. “With such an engaged audience to work with, prestige brands have largely adopted social media in China,” L2 says.
