In recent years, cities are expected to develop in line with the smart city (S.C.) idea. Cities, perceived as attractive places for people to live, must now meet many conditions. A city’s duty is, among others, to meet the needs and expectations of both, its residents and newcomers, offering a wide range of opportunities for entrepreneurs, caring for the natural environment, constantly taking on new challenges, and meeting them for its further development. Thus, the management of a city involves undertaking activities in line with the smart city idea. However, to implement them, they use widely available means, defined as intelligent solutions, e.g., modern ICT technologies. In line with the smart city idea, a city is a center inhabited by people who create a civic and participatory society, having the ability to use the latest ICT solutions and having access to a range of services and solutions offered by the city. Since the smart city idea is considered at many levels, it is still unknown what dimensions or areas related to this concept are the most valuable and stimulating for its implementation. Therefore, the purpose of this article is to study what dimensions or areas related to this idea are the most valuable and stimulating for its implementation. The applied methodology is based on a critical analysis of the available literature in the form of bibliometric and citation analysis and analysis of the keyword characteristics of S.C. co-occurrences. The result of the research is a set of keywords that enable identifying the key dimensions and main areas of the implementation of S.C.
