Reach Your Target Market
Since influencers already have massive followings, they know exactly how to speak to them and what types of content will keep them engaged.
Drive sales up, up, UP!
Influencers act as the non-sketchy middle man between you and your buyers. They authentically recommend your product to the people who need it and those people in turn, buy.
Increase Your Credibility
Every time your product is mentioned by a well-respected influencer, you rack up the brownie points (and the more-likely-to-buy points) with your target customers.
