Types of Influencers

Academics and marketers have been talking about influencers for more than five decades, going back at least to 1955 when Paul Lazarsfeld and Elihu Katz wrote about a “two-step” communication process in their landmark work, Personal Influence (Free Press). Their concept, which has stood the test of time, is that some people have a disproportionate degree of influence on others and can be effective communications channels.

Like word of mouth marketing itself, influencer targeting can come in many forms -- differences in who they are, how they are reached, and what they are called. While it would probably be impossible to inventory every conceivable type or name, what follows is a framework that demonstrates the diversity of targeting options for influencer marketing. Whether aiming at the highest ranking, formal, or institutional leaders, prominent talking heads in the media, grassroots influencers on the internet, or influencers in your neighborhood, all types of influencers can provide the basis for an influencer marketing strategy.

In the table below, we identify five broad categories of influencers based on varying degrees of formal/institutional roles to less formal influencers whose value stems from more personal characteristics -- social networking, personality, and inclination to share opinions. Numerous researchers and marketers have developed names -- some trademarked -- for the various influencer types.
