Many cities have recently chosen to become a smart city. A number of smart city rankings have been created and rank the cities around the world according to smart cities criteria. However, from a reputation point of view, it is not clear which parts of the world shine the most regarding its smart cities initiatives. Higher reputation may attract more investors or startups in the field and contribute to the business development of the territory. It is the reason that in this study we have applied commercially available online reputation tools in order to know which countries in the world have the highest e-reputation with regards to smart cities and may therefore benefit the most from their smart city initiatives. We have found that India has quantitatively the highest online reputation regarding smart cities. More generally, our study has shown that current online reputation management tools can be applied to smart cities and can be used to continuously monitor a smart city e-reputation as well as its potential smart cities competitors aiming at becoming the most attractive smart city in the world.
