While most marketers struggle to generate reach through their social media marketing programs, a handful have unlocked the secret to finding large audiences: Mass Influencers. Our Peer Influence Analysis tool proves that there are two different types of online influencers in Europe: the Mass Mavens who will create more than a billion influence posts this year about marketers' products and services and the Mass Connectors who turn those influence posts into more than 120 billion influence impressions. Interactive marketers must leverage both of these influencer groups in order to get their social media marketing messages in front of the widest possible audience.
