A micro-influencer is a creator with a following in the roughly 10,000–100,000 range who has built a concentrated, engaged audience around a specific niche - fitness, parenting, sustainable living, local food, and so on. Despite smaller reach than celebrity influencers, micro-influencers often deliver stronger engagement rates and more authentic connections with their audience.
For brands, the appeal is cost-effectiveness and relevance. A micro-influencer’s followers tend to be genuinely interested in the niche, making them a better fit for targeted campaigns than a broad celebrity partnership. Running campaigns across several micro-influencers can reach comparable total numbers while maintaining credibility.
