Connected: The Surprising Power of Social Networks and How They Shape Our Lives is not a book about social media marketing, nor is it a business or marketing book at all. However, the insights and data uncovered by co-authors and noted social scientists Nicolas Christakis, M.D, Ph.D. and James Fowler, Ph.D. are a must-read for any marketer interested in igniting word of mouth and becoming the brand of choice amongst their target consumers.
The first thing to understand is that social networks have been around pretty much since human beings have. These complex systems affect us in ways we often aren’t fully aware of – from how we choose our mate to how much weight we gain to whether we vote to purchases we make to if and how much we donate to a cause.
At the heart of this effect is the Three Degrees of Influence Rule. The authors’ research has shown that the spread of influence in social networks ripples out three degrees. Essentially, we have great effect upon and are in turn affected by friends of friends of friends. So if, for example, you have 20 social contacts and those contacts each have 20 social contacts and each of those contacts has 20 contacts, you are indirectly connected to 8,000 individuals whose habits and lifestyle influence you and over whom your choices also have impact. How much impact?
According to the authors, our friend’s friend’s friend has more influence on whether we gain weight than our spouses do. Their research has shown that if a mutual friend becomes obese it nearly triples a person’s risk of becoming obese. Those closer to the center of a social network, with many friends and contacts that cross over, have even more influence.
The assumption might be that social media would explode this effect but Christakis and Fowler’s research shows that when it comes to influence, not all friends are equal. While the average Facebook user (at the time of the printing of this book in 2009) has 110 “friends,” only a subset of these are actually close friends. In their study of Facebook pages of students at a large university on average only 6%, tagged each other in photos, which, according to the authors, indicate true social closeness and intimacy.
At Grow we call this the Genuine Effect – tapping into those networks where “friend” has a meaning that lives outside of Facebook, Twitter and Linked In, applying to those individuals whom you cross paths with in the real world – from your best girlfriend to the office mate you lunch with weekly to more casual acquaintance you might bump into at a party or school fundraiser. These genuine or real world connections hold a different currency and, as outlined in Connected, are those that actually impact our choices and behavior. Noted word of mouth measurement experts The Keller Fay Group report that even in this digital age, 77% of brand conversations are still happening face to face. Having designed and implemented influencer and word of mouth campaigns for scores of brands across a range of categories and demogrpahics we have seen the Genuine Effect in action and its power to build communities of brand advocates.
A recent story in Ad Age further illustrates the difference between on and offline friends and influence. According to the Edelman Trust Barometer, the number of people who view their friends and peers as credible sources of information about a company dropped by almost half, from 45% to 25%, since 2008. With more “friends” online ever more removed, influence becomes diluted and brands should not place value on an influencer solely by his or her count of online followers and friends.
However, while social media has not expanded the Three Degrees of Influence rule it has increased the reach and speed by which this influence spreads. It is how we elected a president and raised millions for Haiti. At Grow, we bake social media into every campaign, viewing it as a publicity layer that can help amplify influencer programs vs. replace them.
So, how do marketers effectively infiltrate social networks? By identifying and authentically connecting with those everyday influencers who are deeply networked and are looked to by their peers as credible sources of information on your category and, most importantly, connect emotionally with your brand. It’s not an automated process that can be housed in a master database or built with a mass email or acquired through a Facebook ad campaign.
To truly tap the Genuine Effect you must forge a relationship with those influencers who can truly serve as an authentic mouthpiece for your brand. Some things are still best done by hand.
