This article attempts to draw a map of user flows and behaviours in the multi-layered CLARIN’s web structure by cross-examining the dynamic movements of different types of users within (and outside of) CLARIN domain. In particular, we analysed the user traffic of several websites including the main website, various CLARIN web applications, and partner websites, as well as the use of single sign-on. Consequently, we are able to have a better understanding of user interactions in the context of a large web ecosystem rather than those of an each individual website. The evolution of web traffic over a year reveals a comprehensive overview of the characteristics of end-users and provides a clue for the next strategic decisions over CLARIN’s user oriented services and business sustainability. This preliminary research also proves the potential of business intelligence of web analytics to measure the impact of aggregation services and complex research infrastructures in cultural heritage and digital humanities alike
