Mega influencers are the people with a vast number of followers on their social networks. Although there are no fixed rules on the boundaries between the different types of followers, a common view is that mega-influencers have more than 1 million followers on at least one social platform. Many mega-influencers are celebrities who have gained their fame offline – movie stars, sportspeople, musicians, and even reality television stars. Some mega-influencers have gained their vast followings through their online and social activities, however. Only major brands should approach mega-influencers for influencer marketing, however. Their services will be costly, up to $1 million per post, and they will most likely be extremely fussy about with whom they choose to partner. In virtually every case, mega-influencers will have agents working on their behalf to make any marketing deals.
