Short answer

A micro-influencer is a creator with a modest but engaged following, commonly cited as roughly 10,000 to 100,000 followers. They often have strong credibility within a niche and closer relationships with their audience. Brands frequently work with many micro-influencers at once for authentic content and engagement at a lower cost per creator.
