I'm just now hearing about Influencer Marketing, a form of marketing where focus is concentrated on influential people rather than those people want to target.
I have never heard of that. Walk me through it please.
What it does is identifies the people who have influence over potential buyers, and directs the marketing toward them rather than the buyers themselves.
You mean like celebrities or Ivana trump?
Sort of. The influencer marketing may come in the shape of testemonial advertising where the, e.g., celebrity plays the role of a possible buyer.
i may have seen some commercials like this on TV, but no examples come to mind.  The idea is for me to relate to the influencer and want to be like them so i buy the product, is that correct?
Exactly. The influence is not so much about persuasion but more about interactions between various parties, in this case the celebrity and the person watching the commercial.
