Posadi derevo is the social campaign, which was aimed at drawing attention to the new service of Promodo,
social media marketing. We dicided to use SMM tools to make Kharkiv greener.
But how? By a competition between districts of the city. 
To vote site's visitor right on the main page had to drag an icon of the tree to the necessary district.
Then he had to connect his account of one of the social networks.
Each district had his own page where all the visitors could see the statistics and comment the campaign process.
