One of the most effective content marketing campaigns to ever exist was Coca-Cola’s, “Share a Coke Campaign.” Many people recognize this campaign immediately. The idea behind it was to personalize Coke bottles with common first names. The campaign was so successful because of the personalization. It influenced people to buy their product because it felt like it was specially made just for them. When you customize a product, it creates an urge for people to buy it. This kind of content marketing worked wonders for the brand.
