Research show that social media are effective channels to use in branding, at the same time Swedish municipalities are increasingly starting to see the importance of branding and reports show that  they are using social media channels for branding purposes. Even though reports show that the municipalities are using social media channels in branding there is a lack of studies done on how they are using social media in branding. To examine this two research questions is developed; (1) What is branding for a municipality and (2) How are municipalities using social media in branding. To examine the research questions different theories are applied and a conceptual framework is developed based on theories from branding, social media and branding in social media. To collect data for the research a qualitative study with three case studies (three Swedish municipalities) is conducted. The primary data from the three cases is collected through face to face interviews with employees responsible for the social media channels. Secondary information is gathered through observations of the municipalities social media channels examined in this thesis, and documents found on internet concerning the municipalities’ use of social media. The analysis of the data is done based on the conceptual framework presented in the theoretical chapter and consists of both within case studies and cross case studies in order to identify similarities and differences among the cases. The findings from this study show that both corporate, employee, and place branding is applied in the municipalities overall branding goals and strategies. Even though the municipalities are examined as organizations in this study employee and place branding goals are identified in order for the municipalities to reach their overall wanted position and image. A further conclusion is that social media has been effective in branding. Social media has enabled the municipalities to reach their branding goals through being transparent, informing, engaging and creating dialogues with their inhabitants and other publics. Through social media the municipalities have managed to establish, influence and create perceptions that have positively influenced their position and image. Facebook, Twitter and Instagram have shown to be efficient social media channels to use in branding and has enabled the studied municipalities to change their perceived image from being unknown organizations to becoming more personal, transparent and increasing the public`s knowledge about the municipalities.
