Influencers: Several types of influencers contribute to the decisions customers make. They may be everyday people who influence the consumer as he makes a purchasing decision. Depending on the decision, the social influencers may be a wife (or husband), friends, peers at work, or even someone the consumer has never even met in real life. Simply put, the people who influence a brand affinity and purchasing decision are the social influencers. They may do this directly by rating products and commenting or by publishing opinions and participating in conversations across the web. Anyone can be a social influencer, influencing someone else’s brand affinity and purchasing decisions, and you, the reader, are probably one, too, without realizing it.
