Micro-Influencer

A micro-influencer is a creator with a smaller but highly engaged audience — typically 1,000–100,000 followers. In B2B, micro-influencers are often the best choice: a 15K-follower LinkedIn creator who's specifically a CRO consultant has more concentrated influence over your ICP than a 500K-follower broad business creator. Micro-influencers typically have higher engagement rates, more authentic audience relationships, and lower cost per post.

Real-World Example

For example, partnering with 10 micro-influencers who each have 20K LinkedIn followers in your exact ICP niche often outperforms one macro-influencer with 500K generalist followers — at comparable or lower total cost.
