Influencer marketing has become very popular among advertisers. With high reach on social media channels, they appear to be the perfect mouthpiece to reach the increasingly important employee target group consisting of millennials. Traditional advertising does not motivate members of this target group to buy, but arouses scepticism. Companies are therefore looking for strategies to integrate influencers into their marketing. This is particularly true in the B2C sector, but success can also be achieved by using influencers in B2B marketing. However, other rules apply here.
