Network of City under the impact of globalization and information technology is an active direction for the last decade of Urban and Regional Studies. Based upon the search interest statistics provided by Google Trends, this article gets peoples online attention data among cities in 2012, maps the main linkage among world cities, and ranks cities according to their international connectedness. Main results confirm that 1) Europe has the largest number of higher-ranking cities in the new global urban network, the next is North America, and the least is South America as well as Africa; 2) Southeast Asian cities except Singapore and Hong Kong all perform poorly under the new criteria; 3) Two types of cities, info-flow-in and info-flow-out, nearly distribute evenly across the main continents; 4) Connection within and between Europe and North America is of the most density and frequency among other intercontinental links. Overall, significant differences exist between the new networks based upon inter-city concern on the Internet and the traditional urban system based on the producer service firms. Interconnectedness of cities to a large extent is influenced by the real geographic location and distance. The research does a beneficial attempt on mining information flow data and provides new insights into city network studies.
