Research has shown the potential of social media to disseminate important information as well as transforming citizen engagement with government. However, implementation remains difficult, especially in public sector organizations. The success, impact, and performance of these new forms of networked interactions are yet to be fully explored, especially at the local level. Many municipalities are still experimenting with the use of social media, and few actively measure their performance on these platforms, as well as their digital interactions with the users. Different models or frameworks have been proposed to describe the types of government communication and activity on social media. They are addressed in this conference paper through three different phases, which refer to forms of government-citizen communication on social media. The original assessment method developed here contributes to the existing literature and provides guidance to practitioners. Empirically, our research relies on a database of cities that have between 100,000 and 500,000 inhabitants in European Union member states located in Central and Eastern Europe. It provides social media metrics for all cities included in our sample (N=82) and compares various indicators on Facebook, Twitter and Instagram, thereby contributing to better assess how social media platforms are used by local governments in the region
