Word of mouth marketing is far more effective than social media when it comes to selling products, said Ted Wright, author of 'Fizz'. Wright added that Twitter and Facebook ads are far less trustworthy than a story recounted by a friend or peer. He said Blue Moon beer by MillerCoors is a brand that is thriving due to word of mouth marketing. Furthermore, Wright said word of mouth marketing is more measurable than a digital marketing campaign because the results are seen on the top and bottom lines, not at the water cooler. Finally, Wright said celebrity endorsers only work if they truly love the product.
