What is a micro-influencer? How a brand picks one

Facts about other tools come from their own sites, with the date we checked. Our editorial policy · About us.

A micro-influencer is a creator with a small, focused audience, usually about 10,000 to 100,000 followers. They post about a niche, such as skincare or home cooking, and their followers may trust them on it. Brands may like them because their audience cares about the topic.

An influencer is anyone with an audience who can sway what that audience buys. A follower is a person who has chosen to see their posts. No official body sets these ranges, so the numbers below are habits of the industry, not rules.

How many followers is a micro-influencer?

Two industry guides, Brandwatch and Shopify, both say 10,000 to 100,000. Brandwatch describes a micro-influencer as a creator "with a following typically between 10,000 and 100,000" (Brandwatch, last updated 18 March 2026). Shopify's guide gives the same range (Shopify, published 29 September 2024). A third guide calls the ranges "typical, not official." It notes that some sources put the micro and macro line at 50,000 or 250,000 (Make Influence, undated, checked 26 October 2026).

So if a brand says "micro," ask for the number. It may mean 8,000 or 80,000.

What is the difference between nano, micro and macro?

The tiers are named by size. The ranges below follow Brandwatch. Shopify differs by one at the edges, for example 9,999 for nano. The mega row comes from Make Influence.

Tier	Followers	Size
Nano	1,000 to 10,000	The smallest tier
Micro	10,000 to 100,000	The tier this guide is about
Macro	100,000 to 1 million	A larger tier
Mega	1 million or more	The largest tier

Look at each account on its own, because follower counts differ by platform.

Why do brands use micro-influencers?

Here are three reasons, in our view.

Fit. A micro-influencer who writes about sensitive skin can reach people looking for exactly that. A larger account may reach more people but a wider mix.
Price. A smaller audience may ask for less. Some may take a free product or a commission. We give no rate here, because it varies by niche and platform.
Access. You may be able to message them yourself, without an agent.

Guides often add that micro audiences are more engaged. Engagement means how much people react, through likes and comments, compared with the follower count. Shopify's guide makes this claim but cites no source. Treat it as an idea to test, not a fact (Shopify, checked 26 October 2026). Look at the real posts instead.

How can you pay a micro-influencer?

Here are four ways to pay.

A gift. A free product, with no promise of a post.
A flat fee. A set payment for a post or video.
A commission. A cut of each sale that comes through their link.
A mix. A gift plus a commission.

A commission pays only when someone buys, so it carries less risk for a small brand. Our guide on what commission a Shopify program should pay shows the market range from 168 public programs. The median base rate was 10% on 23 October 2026 (our commission research).

Five checks before you pick one

A follower count tells you little. Run these five checks before you write to anyone.

Is the content about your niche? Scroll their last 20 posts. If a skincare account also posts about cars, the audience is mixed.
Are they active? Look for a post in the last month. An account that stopped in spring is not a lead.
Does the audience match yours? Read the comments. Real questions about the product type are a good sign. Strings of emojis from strangers are not.
Do they label paid posts? The US Federal Trade Commission expects people to say clearly when they earn a commission or get a free product (FTC, checked 26 October 2026). If a post looks like an ad and is not labelled, skip them.
Can you reach them? An email, a contact form or a link in their profile. If there is none, they may not want offers.

These checks matter because lists contain noise. In a check of 30 random rows from our scan of 30 Shopify brands (22 October 2026), 9 were not promoters, about 30% (a range of about 17% to 48% at that sample size). The method is on the research page. Open each page before you gift or pay anyone.

Where do you find micro-influencers?

In our scan, most of the people we found were on pages, not social feeds. These counts are people who promote brands, not micro-influencers, because the scan did not measure follower tiers. They are also before our 30-row noise check. In the scan, 64% of the people shown had a review, roundup or comparison page as the page where we found them. TikTok and Instagram together gave only 66 of 2,924 people (our scan data).

That does not mean social creators are wrong for you. It means a search that stops at social media misses most of the people writing about brands like yours. Our guides on where to find affiliates and finding affiliates for a Shopify store show both routes.

What should the first message say?

Keep it short. Name one real post, say what you make, and ask one thing. Our guide to the affiliate recruitment email has a sample you can adapt. If you plan to send a gift, offer first and ship after they say yes.

Frequently asked questions

What follower count counts as micro?

About 10,000 to 100,000, per Brandwatch and Shopify. No official body sets the range, so some guides draw the line elsewhere.

Are micro-influencers worth it?

They can be, if the audience fits your product. Fit is a better guide than size, in our view. Pay in a way that fits your risk, such as a gift or a commission. Check each person with the five checks above.

What is the difference between micro and nano?

Nano is 1,000 to 10,000 followers and micro is 10,000 to 100,000. Nano accounts have fewer followers. Micro accounts have more, and often follow a niche topic.

How do I find micro-influencers?

Search for the pages and channels that already cover your kind of product. In our scan, review and roundup pages were the biggest group. Then add creators on TikTok and Instagram. Open each one before you contact them.
