Maes is Belgium’s second most popular beer and also Belgium’s 3rd most common surname. Since the market leader for beer in Belgium was outselling Maes 4 to 1, they decided to garner support from all the Maes families in Belgium by giving them a free barrel of beer.
The eligible families had to sign up for this special offer through a custom Facebook app that also allowed them to book a pub on a chosen date while inviting all their friends. The campaign was a huge success and pushed the Maes fanpage into 6% of the most active Facebook pages worldwide! 😎
