Help me out with quick pop quiz. What percent of word of mouth do you think happens online? In other words, what percent of chatter happens over social media, blogs, e-mail, and chat rooms?
If you're like most people you probably guessed something around 50 or 60 percent. Some people guess upward of 70 percent, and some guess much lower, but after having asked this question of hundreds of students and executive, I find that the average is about 50 percent.
And that number makes sense. After all, social media have certainly exploded of late.
Millions of people use these sites every day, and billions of pieces of content get shared every month. These technologies have made it faster and easier to share things quickly with a broad group of people.
But 50 percent is wrong.
Not even close.
The actual number is 7 percent. Not 47 percent, not 27 percent, but 7 percent. Research by the Keller Fay Group finds that only 7 percent of word of mouth happens online.
Most people are extremely surprised when they hear that number. "But that's way too low," they protest. "People spend a huge amount of time online!" And that's true.
People do spend a good bit of time online. Close to two hours a day by some estimates. But we forget that people also spend a lot of time offline. Most than eight times as much, in fact. And that creates a lot more time for offline conversations.
We also tend to overestimate online word of mouth because it's easier to see .... But we don't think as much about all the office conversations we had over the same time period because we can't easily see them.
