While the concept of steering marketing communications towards a small number of influential networkers was suggested as far back as the 1950s, it has been in the age of Web 2.0 that it has truly taken flight. As social networks continued to grow rapidly, so has interest in influence. Global companies are realising the importance of targeting high profile bloggers, journalists and celebrities, and have increasingly sought to reach out to these influencers for endorsement and to drive word-of-mouth about the brand. But FMCG brands like Snickers can easily identify popular celebrity bloggers, businesses in other fields can have a harder task to find relevant influencers. To cater for this, a new wave of influencer scoring, based on social media analytics, has emerged, most notably Klout, Kred and PeerIndex.
