How to tell if a creator reaches your target demographic
Quick answer
Stop judging the audience by the creator and check the audience data directly. The creator demographic is not the audience demographic, a young creator can have an older following, so what you verify is the audience breakdown itself: their age, location, gender and interests against your buyer persona. The signals that matter are real audience location matching your market, age and interest alignment with who buys from you and authenticity so you are matching against real people not bots. A creator who looks like your customer can still have an audience that is nothing like them, which is why you read the audience numbers, not the creator vibe.
I keep assuming the audience of a creator mirrors the creator but I get burned. How do I know if an influencer audience matches my target demographic for real?
