Social Media and Business

Businesses use social media to engage their customers and market their products but they don’t always get it right. An example of a social media disaster was when, in 2012, McDonald’s launched a Twitter campaign where they paid a large sum of money to promote the hashtag #McDStories They hoped customers would share positive stories of their visits to their restaurants. However, people started sharing negative reviews, the company realised that their reputation was at risk and they quickly pulled the campaign.

What lessons can be learned from this failed social media campaign and how can companies design campaigns to be effective and engaging for customers?
