Running an effective, creative and memorable Facebook marketing campaign is challenging, no doubt. The average Facebook user is connected to more than 80 community pages, groups and events, and breaking through the clutter isn’t easy. That’s why these campaigns by big brands like National Geographic, Alamo and Craftsman really impressed us as attention-grabbing and interactive. These are seriously cool and fun to play with, yet still achieve the core goals of obtaining more followers, creating customer loyalty, engaging and connecting with their target audience and ultimately selling products. Which one is your favorite?
