     Accounts with between fifty thousand and two hundred thousand followers are considered “microinfluencers,” and tend to have higher engagement rates—that is, a larger share of their followers like, favorite, or comment on their posts—than those with millions of followers.

     By now you have probably heard of influencers, that group of internet-famous people who have more than a million social media followers and can make big money by plugging various brands. And you may have even heard of microinfluencers, who do the same thing for a still sizable but somewhat smaller social media audience — from the tens to low hundreds of thousands.
