While there is no one criteria that indicates whether or not a person qualifies as an influencer, people with as little as 20,000 followers may begin to exert influence in their respective fields. According to the Advertising Standards Agency in the United Kingdom, someone who has 30,000 or more followers qualifies as a celebrity. From nation to country and sector to industry, the number of followers necessary to be positioned as an influencer might vary significantly. Lastly, it's important to note that influencers for consumer products often have a far higher number of followers than influencers for B2B firms.
