For a long time now, word-of-mouth has been one of the most efficient forms of advertising. Also, unlike analog word-of-mouth, influencer marketing takes place entirely online. However, since everything takes place online, metrics like the number of likes, shares, comments, etc. may be used to properly gauge the audience's reaction. By definition, influencers attract a sizable and devoted online following. These fans see them as authorities in their fields, so they trust anything they say. Even though the idea may seem simple, there are effective ways to use influencers to raise brand awareness.
