How many followers does a micro-influencer have?

Definitions vary. A common range is 10k–100k. Nano is often under 10k. Macro is larger. The useful test is whether the comments are human and on-topic.

Why use micro-influencers?

Lower fees, tighter niches, and often better conversion than a celebrity who will not use the product. More work to brief many of them.

Q: What is a micro-influencer?

A micro-influencer is a content creator with a relatively small but engaged audience, commonly defined as about 10,000 to 100,000 followers, trusted in a niche.

A micro-influencer is a creator whose audience is small enough to still feel like a room. Not a stadium. You pay them because the comments look like people, not a bot farm with a ring light.

Definition

A micro-influencer is a creator with a modest following and a real niche. The usual bucket is roughly 10,000 to 100,000 followers on the platform that matters. Under that, people say nano. Over that, mid or macro. The labels move. The job does not: they can convince a specific room.

They show up in influencer campaigns because a thousand true fans beat a million muted accounts. They are not automatically honest. Small accounts fake numbers too. Read the comments.

Micro vs nano vs macro

Label	Rough size	You buy
Nano	Under ~10k	Trust, DMs, high effort per post
Micro	~10k–100k	Niche reach you can still brief
Macro / celebrity	Hundreds of thousands+	A billboard with a face

A newsletter with 8,000 openers can outperform an Instagram with 80,000 ghosts. Count the audience that can hear them, not the badge.

When they are the right tool

Your product is for a scene, not “everyone 18–54.”
You have a unique URL and a landing page that converts warm traffic.
You can brief ten humans without a 40-page brand book.
You need proof, not a Super Bowl story.

When they are wrong: you need national awareness by Friday, or you cannot handle invoices and FTC disclosures, or your product is embarrassing and you hoped a pretty person would launder it.

How to work with one

Pitch the artifact and the date, same as a small collaboration. Pay on time. Let them talk like themselves. Demand a disclosure. Track the code. If it works, offer a 90-day partnership instead of a new cold DM every month.

Do not ask for their rate and then say “exposure.” They have exposure. They need rent.

FAQ

How much does a micro-influencer cost?

Anywhere from product-only (bad default) to a few hundred or a few thousand per post, plus usage. Ask. Compare to what ads cost to reach that niche.

Is engagement rate the metric?

It is a clue. Sales, trials, and kept subscribers are the metric. A high engagement rate on giveaways is a prize-hunter magnet.

Can a micro-influencer be a newsletter writer?

Yes. A list is often the better micro-audience. Treat a guest issue like a post with a longer shelf life.
