FiIl in the blank: _______ are the most challenging group of people to work with if you don't know them personally, but in order to achieve success through social media marketing they are potentially the most rewarding.

Influencers are the correct answer because they are individuals with a dedicated following who can significantly impact purchasing decisions. Building relationships with influencers often requires careful negotiation and understanding their personal brand, making them challenging to work with without prior connection. However, their ability to reach a targeted and engaged audience makes them incredibly rewarding for social media marketing success. Your employees and brand advocates are typically easier to engage as they already have a vested interest in your brand. Followers are the general audience and while important, they are not typically the "most challenging" group to work with in the same way an external influencer is.
