The subject of the research is to determine the number of online (e-municipality) applications, which is a basic sub-component of smart governance, of the metropolitan municipality, which is the most effective local government unit in Turkey, by grouping them within itself, and to determine the number of applications compared to other municipalities. The main purpose of the study is to identify local online applications in Turkey, to group them, to determine how many are applied specifically to metropolitan municipalities and to create score tables among metropolitan municipalities. Thus, it will be possible to compare the success scores of metropolitan municipalities by determining which online services they provide and which ones are insufficient. With the comparisons made, the supply and demand ratios of online services and applications will also be revealed. The scope of the research is 30 metropolitan municipalities in Turkey. In the research, the corporate web pages of the metropolitan municipalities were analyzed by the scanning (content analysis) method. In this context, the corporate web pages of all metropolitan municipalities were examined in detail between 15.03.2022 and 15.04.2022 and online service types were determined by using the data obtained, grouped within themselves and score measurements were made. The existing online services of metropolitan municipalities were evaluated in general and by comparing them with each other. The data obtained through the research were grouped within themselves, and the types of services in each group were listed separately in 11 separate tables for all municipalities. Finally, an evaluation and comparison was made over the grand total of 11 score tables. At the end of the study, it has been determined that the average success rate of 30 metropolitan municipalities in Turkey is 71.99%. In addition, it was seen that the most successful metropolitan municipalities were Ankara BB (91.39%), Istanbul BB (90.57%) and İzmir BB (89.34%).
