You’re not going to find a better example of a viral type video built specifically to drive an action than this one.
Notice how smart this was done? A powerful, emotional story, told without voice, in music and images.
Also notice how smart the call to actions are at the end of the video? They don’t interrupt. They are relevant. They help you easily share it.
This video will go viral because it’s that good. And frankly, this is something you could make over at www.Animoto.com for free.
Use emotions and tell stories.
