I would love the source for this. It seems too ridiculous to be true unless they're using a non-standard definition of 'influencer'.
"Nano" influencers, according to this particular company, are people with 1000-3000 followers, Micro are 1,000-100,000, Macro are 100,000+, etc. Here's another example with slightly different values: https://www.cmswire.com/digital-marketing/social-media-influ...
Because this is now big business, I'd expect convergence on a common definition some time relatively soon.
This is not including the important and elusive count of true influence. The basic ways are usually like/bookmark, repost, replies/comments. An overlap can also be if your posts get referenced outside the social media network a lot too.
Counting a couple thousand followers as categorization is meaningless since they could be barely interacting to really interacting. And at such a small follower count, low interaction could mean someone with a couple hundred followers is more of an influencer in terms of literal influence than someone with 10x followers.
Different social media apps and then non social media like blogs or podcasts all have different thresholds for what is considered “big”.
With smaller counts, usually if someone is following 4K and is followed by 3K, they aren’t any more “influential” than an active liked person with a couple hundred followers.
Still not perfect but looking at basic interaction metrics will help a lot more as well: likes/favs/bookmarks, reposts, replies/comments. There are overlapping metrics like embedded or referenced count outside the social media app itself. Add in trajectory, history especially to verify this isn’t a BS blip of bought interactions and followers.
Further than that, getting a general view of the cohort of followers like how many are active, how many have profile pics, how many are bots or only on to market their own stuff, etc
The standard definition is more or less "someone who posts glamorous shots of themselves on social media to build an audience they can influence and then monetize". A non-standard definition would be one which most people would find misleading or not fitting for the term.
I also wonder what the poll looked like, I find it hard to believe people over 30 would want to become influencers unless it was worded something like "Would you like to make millions of dollars if it meant becoming an influencer?"
