Influencer marketing has a person with an audience and authority (a blogger, industry expert, public figure) recommend a product. Its strength differs from plain advertising: the recommendation comes not from a strange brand but from someone the audience trusts.
The key is choosing the right influencer: not follower count but the audience's fit to your ICP and the level of trust decide. A small but precisely niched (micro) influencer is often more useful than a large one.
