Micro-influencers

Micro-influencers are creators with 10,000 to 100,000 followers and an often closely connected, topic-focused community.

They reach fewer people than large channels but often have a higher engagement rate and lower prices. That makes them a good choice for niche products and local campaigns. Channels with fewer than 10,000 followers are called nano-influencers. The thresholds are a convention and vary by source.
