Design and development of a Facebook application for HTC Bulgaria. The HTC Here’s To Change Facebook application is part of the HTC’s marketing campaign – Here’s To Change, aiming to renovate the urban environment to make a better place for everyone. During the game Facebook users can choose the next place that the artists from Destructive Creation are going to improve. Users have to vote for one of 7 locations in Bulgaria that they want to be renovated. One voter will win the HTC One smartphone. Additionally, users have to like HTC Bulgaria Facebook page in order to participate in the game. We have activated automated postings on users’ Facebook walls, too. The app is supported with Facebook ads which increased users engagement with 150% in the first week of the campaign.
