Micro-influencer
A micro-influencer is a creator with a modest but focused following, roughly 10,000 to 100,000, known for high engagement and audience trust within a specific niche, making them effective for targeted marketing despite limited overall reach.
Follower brackets are fuzzy and vary by source, but micro-influencers generally sit between nano-influencers, who have a few thousand followers, and macro or mega accounts with hundreds of thousands or millions. The defining trait isn't the number, it's the relationship. A tightly focused audience tends to engage more, trust recommendations more, and share more interest in a specific topic. That's why engagement rate often falls as follower count rises: bigger audiences are more diluted.
For brands, micro-influencers offer targeted reach at lower cost, often with better conversion per dollar than a celebrity partnership. A creator known for one clear subject can move a niche audience that a broad campaign never touches. The tradeoff is scale. You reach fewer people per post, so campaigns usually mean coordinating several creators rather than one big name.
The common misconception is that more followers always means more influence. In practice, a specialist with 20,000 engaged, on-topic followers can drive more action than a generalist with 500,000 passive ones. Match the creator's niche to the offer, and audience quality tends to beat audience size.
