Analytics nightmare: 82 percent of mobile sharing is done through dark social

Globally, 82 percent of content shared on mobile is shared through messaging, email or text, according to a report released today from ad platform RadiumOne, called the “The dark side of mobile sharing.” In 2014, it was below 50 percent. Just 13 percent is shared via Facebook, and the remaining 10 percent through the other public social networks.
RadiumOne based the numbers on the actions of the 940 million people globally on the platform.
