TransformerA micro-influencer is a creator with a mid-sized, focused audience, most commonly defined as 10,000–100,000 followers (nano is under 10,000; macro starts around 100,000). For a first campaign, most brands should start with micro and nano creators: they cost far less per post, their posts reach a larger share of their followers, and you can test several of them for the price of one macro creator. Judge them on cost per signup with a tracked link, not just CPM, because CPM benchmarks vary wildly between sources.
What is a micro-influencer?
There's no official definition. The most common split:
| Tier | Followers |
|---|---|
| Nano | 1,000–10,000 |
| Micro | 10,000–100,000 |
| Macro | 100,000–1,000,000 |
| Mega | 1,000,000+ |
Influencer Marketing Hub defines nano as under 10,000 followers and micro as 10,000–100,000. Some datasets draw tighter lines: OpenSponsorship's data uses 10,000–50,000 for micro, and impact.com uses 15,000–75,000. When you compare benchmarks, check which definition they use.
What is a nano-influencer?
A nano-influencer is a creator with a small, close-knit audience, usually 1,000 to 10,000 followers. Definitions differ by source: Influencer Marketing Hub counts nano as under 10,000 followers, OpenSponsorship's data uses under 10,000, and impact.com draws the line at under 15,000. What they share is a following small enough that the creator often knows their audience, and an audience that trusts them like a peer.
What's the difference between nano and micro influencers?
Size, reach and price. From inBeat's October 2026 analysis of 1,527 completed paid deliverables (OpenSponsorship data, medians):
| Nano (under 10K) | Micro (10K–50K) | |
|---|---|---|
| Median fee per deliverable | $134 | $150 |
| Views per follower | 19.9% | 4.6% |
| Engagement per view | 4.6% | 4.3% |
| Median cost per view | $0.13 | $0.14 |
Nano creators' posts reached a far larger share of their followers, at a similar cost per view; micro creators reach more people in absolute terms per post.
When should a brand pick nano creators on X?
- Your buyers are a small, specific group, such as developers using one framework, and the right voices are small accounts.
- You want to test angles cheaply: several nano posts for the price of one bigger creator. On Transformer, the default price for an X post from a creator under 5,000 followers is $50 ($40 to the creator).
- Trust matters more than reach, for example a technical product people buy on a peer's recommendation.
Mix in micro creators when you need more reach per post.
Should brands start with micro or macro influencers?
For a first campaign, usually micro (and nano). The data on paid deliverables, from inBeat's October 2026 analysis of 1,527 completed OpenSponsorship deals (medians, January 2025–June 2026):
| Tier | Median fee per deliverable | Views per follower | Engagement per view |
|---|---|---|---|
| Nano (under 10K) | $134 | 19.9% | 4.6% |
| Micro (10K–50K) | $150 | 4.6% | 4.3% |
| Mid (50K–250K) | $417 | 2.0% | 2.9% |
| Macro (250K–1M) | $517 | 1.5% | 2.6% |
| Mega (1M+) | $2,727 | 1.1% | 3.5% |
What that means for a first campaign:
- Cost: a micro creator's median fee was less than a third of a macro creator's, so the same budget tests three or more creators instead of one.
- Reach relative to size: smaller creators' posts reached a much larger share of their followers.
- Engagement: viewers engaged more with nano and micro posts than with mid and macro ones.
- Trust and fit: a creator with a focused audience in your niche reads as a peer recommendation; see Why smaller creators often outperform.
Macro creators still win on raw reach per post and can make sense for a launch once you know your message works. Brands are moving toward smaller creators: in Influencer Marketing Hub's 2026 benchmark survey, 52.83% planned to expand work with micro creators and 51.43% with nano creators, against 20.59% for macro.
The dataset leans toward sports, wellness, food and lifestyle, so treat it as a direction, not a price list for X.
What is a good CPM for a sponsorship?
CPM is the cost per 1,000 views (or impressions):
CPM = fee ÷ views × 1,000
A $150 post that gets 10,000 views has a CPM of $15.
Benchmarks disagree by more than 10×, because they measure different things: OpenSponsorship's median cost per view of about $0.13 works out to roughly $130 per 1,000 views, while Aspire reported an all-platform average CPM of $2.68 for 2025 (both via inBeat, which warns they can't be compared). On X specifically, Collabstr's 2025 data showed an average asking price of $179 and an average payout of $76 per deal.
A practical rule: compare a creator's CPM with what you pay for the same audience in ads, and remember a creator's post carries a recommendation that an ad doesn't.
What matters more than CPM?
Cost per result. Give each creator their own tracked link and compute:
Cost per signup = fee ÷ signups from that creator's link
A $250 post with 12,000 views and 25 signups costs $10 per signup, even if its CPM ($20.83) looks high next to an ad. Compare that with your paid-ads cost per signup, then re-book the creators who beat it. On Transformer, every accepted offer has its own tracked link, and you report signups or sales from your backend with the click id; see How do you measure the results of creator marketing?
How can micro-influencers get brand deals?
- Pick a niche and say it in your bio and profile.
- Post consistently about your topic; brands check recent posts.
- Show engagement, not just followers: replies and clicks are what small accounts win on.
- Have a rate card with prices per format; see How to make an influencer rate card for X.
- Be findable on a marketplace where brands search for creators, and say you're open to offers.
- Deliver and disclose properly, every time. A record of good sponsored posts gets you re-booked.
