Leading Influencer Marketing Agencies You Have to Know in 2021 [Updated]

Many businesses prefer to outsource their marketing to an advertising agency. They might be too small to warrant investing in an in-house marketing team. Alternatively, they may be large and have a sufficient budget to leave their marketing to the experts. Influencer marketing, however, is entirely different from most forms of traditional marketing, and many general-purpose advertising agencies have yet to take the leap into this new territory. This has left space for specialist influencer marketing agencies to set up and fill the void.
