The paper provides an overview of the state of activity of art museums in the regions of Siberia in different social networks. Also, the authors monitor the presence of the official website of the museum and its presence in social networks. In addition, an attempt to give a definition «informational image of the museum» is made, and a selected list of art museums in the regions of Siberia is provided. Within the framework of the study, the authors developed recommendations for improving the information image of an art museum such as: group design, museum information, a fixed record, museum collection materials and publications. Moreover, the authors give the best examples of using the site and social networks by the museums to increase users’ activity during a pandemic. So, the authors prove that the official website and work with social networks is an integral part of museum activities aimed at improving a modern museum.
