Influencers are opinion leaders who gather a loyal audience around them. They are not necessarily bloggers making money from ads. They can be actors, athletes, musicians, scientists—professionals in their fields whose words are listened to and trusted.
For example, a publishing editor shares behind-the-scenes aspects of their work: how they select manuscripts, which writers have a chance of getting a contract, and which conferences are worth attending. A marketer predicts trends and shares successful
advertising campaigns from their clients.
It’s not necessary for an influencer to have a million followers. Often, experts don't aim to promote their social media, and they may have 2–5 thousand followers. For brands, this number is not as important. Due to their authority and knowledge, influencers can influence purchasing decisions—something that works in the long term.
Typically, opinion leaders collaborate with brands they use themselves. For instance, a publishing editor might announce a course for writers where they give a lecture. A marketer might test a new social media analytics service and share their review.
Such content appears organic and doesn’t resemble classic advertising posts written using formulas like AIDA (Attention, Interest, Desire, Action). The audience trusts the opinion of a specific person and buys the product, understanding that it’s an honest review.
