What is a micro-influencer?

Also called micro influencer, micro creator.

A micro-influencer is a social media creator with a smaller but engaged following, often described as roughly 10,000 to 100,000 followers, who is trusted within a particular niche, community or local area.

Why it matters

Micro-influencers are often more affordable and easier to reach than big names, and their followers tend to share a specific interest or location. For a small business with a local or niche customer base, a creator whose audience is mostly your kind of customer can matter more than a much bigger audience spread across the world.

Example

A yoga studio partners with a local wellness creator whose followers are mostly in the same city. She attends a class, posts an honest reel labelled as a gifted visit, and shares a code for a free first session. The studio can count exactly how many people used the code.

Micro vs nano vs macro influencers

There is no official standard for influencer tiers, and different agencies and guides draw the lines in different places. As checked on 14 October 2026, Sprout Social and Influencer Marketing Hub both put micro-influencers at 10,000 to 100,000 followers and nano-influencers at 1,000 to 10,000. Influencer Marketing Hub puts macro-influencers at 100,000 to 1 million and mega-influencers at 1 million and above, and itself says these bands shouldn't be treated as hard rules.

Treat the bands as a rough guide. What matters more than the exact count is whether the creator's audience matches your customers, and whether their followers genuinely engage.

  • Nano: commonly 1,000 to 10,000 followers. Often a local or very specialist voice.
  • Micro: commonly 10,000 to 100,000 followers. A clear niche with an engaged audience.
  • Macro: commonly 100,000 to 1 million followers. Broader reach and usually higher fees.
  • Mega: commonly 1 million or more. Celebrities and the largest creators.

How to find micro-influencers yourself

You don't need special software to start. Look where your customers already are:

  1. Check who already tags or mentions your business, or your competitors.
  2. Search local location tags and niche hashtags your customers use.
  3. Look at who your best customers follow and who comments thoughtfully on posts in your niche.
  4. Shortlist creators whose content you would be happy to see next to your brand.
  5. Check engagement quality: real comments from real people, not just emoji or generic praise.
  6. Look at where their audience is. A local business needs a local audience.

How to approach a micro-influencer

Keep the first message short and personal. Say who you are, why you like their work, and what you are offering, whether a free product, a visit, a fee or a commission. Make it clear whether posting is expected. Many creators at this size handle their own messages, so a friendly, specific note gets further than a template.

Agree the details in writing before anything is posted: what they will share, when, how it will be labelled as an ad or a gift, whether you can reuse the content on your own accounts, and what they will be paid.

Common mistakes

Working with smaller creators is low-risk, but these errors still waste time and money.

  • Picking creators by follower count without checking where their audience lives.
  • Ignoring signs of bought followers, such as sudden jumps in followers or comments that don't relate to the post.
  • Sending a generic copy-and-paste message to dozens of creators.
  • Expecting a post in return for a gift without agreeing it first.
  • Running one post and judging the whole approach on it. Partnerships usually work better over several posts.

Common questions

How many followers does a micro-influencer have?

Commonly 10,000 to 100,000, according to guides such as Sprout Social and Influencer Marketing Hub. There is no official definition, so some agencies use different bands.

Are micro-influencers better than big influencers for small businesses?

Often, because they cost less and their audiences tend to be more focused. The best choice is the creator whose followers most closely match your customers, whatever the size.

Do micro-influencers need to label sponsored posts?

Yes. Disclosure rules apply regardless of follower count, including for gifted products in the US under FTC guidance.
