A micro-influencer strategy is a type of influencer marketing that involves partnering with individuals who have a smaller but highly engaged following to promote a brand’s message, product or expertise within a targeted niche. Micro-influencers typically have between 10,000 and 100,000 followers, though in B2B, influence is more often defined by audience quality and subject matter credibility than follower count alone.

In B2B influencer marketing, micro-influencers are often consultants, practitioners or industry creators with strong domain authority and trusted voices in their fields. Unlike macro-influencers, who offer broader reach, micro-influencers bring authenticity, trust and more meaningful engagement with highly focused audiences.

A B2B micro-influencer strategy may include sponsored posts, guest content, podcast interviews, webinar participation or co-marketing initiatives across channels like LinkedIn, newsletters or industry blogs. Marketers often track metrics such as engagement rate, click-throughs, qualified leads and audience sentiment to assess performance.

When thoughtfully executed, a micro-influencer strategy can boost brand credibility, expand reach within key buyer segments and generate high-quality engagement — often with greater cost efficiency than large-scale influencer campaigns.
