Definition & Differences
What Are Micro‑Influencers?
Micro‑influencers are defined as creators with 10,000 to 100,000 followers. They often anchor their content in niche topics—be it sustainability, local travel, plant care, or tech reviews making them niche influencers who resonate deeply with specific communities.
What Are Nano‑Influencers?
Nano‑influencers have fewer than 10,000 followers, often ranging from a few hundred to just under 10K. Despite smaller follower counts, they boast exceptionally high engagement and deeply personal connections with audiences.
How They Differ from Macro/Mega‑Influencers
- Scale vs Trust: Macro/Mega‑influencers (100K+ to millions of followers) offer reach, but often lack genuine connection. Micro and nano creators, by contrast, foster authenticity and trust.
- Engagement Rates: As follower count grows, engagement typically drops. HypeAuditor data shows nano‑influencers (<5K followers) reaching 2.53% engagement, while mega‑influencers hover around 0.92%.
- Cost Efficiency: Smaller influencers often deliver higher ROI at lower costs—a trend growing stronger in 2024–2025 (see Brand Benefits).
