Micro Influencers: What They Are and How Brands Use Them
Micro influencers are creators in the middle of the size range: the IAB’s February 2025 creator economy map puts “micro” at 10,000 to 50,000 followers, between its Nano and Mid tiers. Checked against IAB: Creator Economy Ecosystem Mindmap (February 2025)Industry convention The band is a convention rather than a rule, and it measures audience size only, not a creator’s niche, quality or price.
This guide is for brands planning a micro influencer programme: where to find creators, what to put in the brief, how pricing works and what disclosure rules ask of both sides. Creator size is only one input; the goal, budget and tracking come first in an influencer marketing strategy.

What is a micro influencer?
A micro influencer is an influencer whose following falls in the micro tier of a size convention: larger than a nano creator’s, smaller than a mid-tier or macro creator’s. Cambridge Dictionary defines an influencer as “a person active on social media who is able to influence people’s opinions or to persuade them to follow a particular lifestyle or buy a particular product”. Checked against Cambridge Dictionary: influencerIndustry convention “Micro” only adds a size.
That matters when you plan a budget. A tier tells you roughly how many people follow a creator. It doesn’t tell you who those people are, whether they trust the creator or what a post costs. Creators under 10,000 followers have their own guide: nano influencers.
How many followers does a micro influencer have?
10,000 to 50,000 in the IAB’s bands, which put Nano at 1,000 to 10,000 and Mid at 50,000 to 500,000. Checked against IAB: Creator Economy Ecosystem Mindmap (February 2025)Industry convention Other publishers draw the lines elsewhere, so the same creator can be “micro” in one report and “mid-tier” in another. When an agency or platform quotes tiers, ask whose bands it uses.
No regulator or platform we checked defines the tiers.

Why do brands use micro influencers?
For reasons of fit rather than proven performance: micro creators qualify for the platforms’ own deal tools, their posts can be reused as ads with permission, and working with several at once lets you test before you commit. You’ll see claims that smaller creators win more engagement or sales. This guide quotes no such benchmarks; judge each creator on their own numbers with our engagement rate calculator.

- Their posts can become your ads. With the creator’s permission you can run their post as a Meta partnership ad, and they can revoke that permission at any time.

- You can test before you commit. Splitting a budget across creators in different niches or cities shows which audiences respond, provided you track each creator’s conversions, and give repeat deals to the creators who fit.

What goes in a micro influencer brief?
Put the deliverables, dates, claims, disclosure, ad rights and payment in writing, and leave the voice to the creator. A checklist:
- Deliverables: platform, format, number of posts and whether you approve drafts.
- Dates: when the product arrives and the posting window. The FTC says influencers can’t talk about experience with a product they haven’t tried, or, when paid, call it terrific if they thought it was terrible, so ship early and don’t script the verdict. Checked against FTC: Disclosures 101 for Social Media Influencers
- Claims: only what you can prove. The same FTC guidance says influencers can’t make claims that need proof the advertiser doesn’t have.
- Disclosure: the platform label to switch on and the words to use in the caption (see the disclosure section below).
- Ad rights: if you want to run the post as a partnership ad or Spark Ad, agree it here, since the creator grants that permission on the platform.
- Payment: amount, timing and method. Meta says brands pay creators for branded content off the platform; it doesn’t support payments through the Instagram app or Facebook. Checked against Instagram Help Center: About branded content on Instagram
How much do micro influencers charge?
There’s no official rate: each creator sets a price, and you negotiate from their rate card. This guide prints no market averages. The platforms’ deal tools show where prices come from instead:
- TikTok One asks creators for an expected rate, which advertisers can see. Checked against TikTok Creator Academy: How to set up TikTok One so brands want to work with you (last updated Aug 18, 2026)
- On Instagram’s creator marketplace, a brand’s project states the rate. Checked against Instagram Help Center: Eligibility requirements for creators on Meta Creator Marketplace
- YouTube Creator Partnerships lets creators set desired rates for long-form and Shorts partnerships, and the “Earn” figure in a brand’s inquiry is the advertiser’s estimate, not a final offer. Checked against YouTube Help: Get started with YouTube Creator Partnerships
Expect the quote to change with what you ask for: the number of deliverables, rights to run the post as an ad, exclusivity and turnaround. Creators can set out their prices with our influencer rate card template, and our Instagram money calculator estimates a sponsored-post range from followers and engagement rate. Brand deals aren’t a creator’s only income; how to earn money from Instagram covers the rest.
What disclosure do micro influencers need?
The same as any influencer: none of the regulators below exempts small accounts, so a paid or gifted micro post needs a clear label in the post itself. The main rules, summarised (not legal advice):
- United States: the FTC’s Endorsement Guides, revised in 2023, Checked against eCFR: 16 CFR Part 255 — Guides Concerning Use of Endorsements and Testimonials in Advertising count payment and free or discounted products as material connections, which must be disclosed clearly and conspicuously when the audience wouldn’t expect them. Checked against eCFR: 16 CFR § 255.5(a) Disclosure of material connections FTC staff say a platform’s built-in tool is “not necessarily” enough and it’s always best to add your own disclosure. Checked against FTC: FTC's Endorsement Guides: What People Are Asking The FTC’s older Disclosures 101 (2019) adds that a creator given free or discounted products should disclose even when they weren’t asked to mention the product. Checked against FTC: Disclosures 101 for Social Media Influencers
- United Kingdom: the CMA’s guidance for content creators, updated in September 2025, treats any incentive, gifts included, as payment, Checked against CMA (GOV.UK): Social media endorsements: guidance for content creators and the ASA and CMA’s influencer guide (third edition, 2023) expects an upfront label such as #Ad. Checked against CAP and CMA: Influencers' guide to making clear that ads are ads (3rd edition, 2023), pp. 7–8
- Canada: the Competition Bureau (on a page last modified in January 2022) says influencers should disclose all material connections, such as money, commissions or free products. Checked against Competition Bureau Canada: Influencer marketing and the Competition Act Ad Standards, the industry’s self-regulatory body, updated its own disclosure guidelines in fall 2025. Checked against Ad Standards (Canada): Influencer Marketing
- Australia: the ACCC said on 7 December 2023 that influencers should disclose a promotional post in a way that is immediately obvious, including when they received free products or other gifts, and that influencers and brands may break the Australian Consumer Law if consumers are misled into thinking sponsored posts are genuine. Checked against ACCC: Scrutiny of influencers and businesses for misleading advertising and online reviews continues (media release, 7 Dec 2023) In March 2026 it said it would soon release specific guidelines for influencers. Checked against ACCC: PhotobookShop pays penalties for influencer reviews (media release, 24 Mar 2026)
- The platforms: Instagram wants its paid partnership label on paid posts, gifted products and affiliate links, Checked against Instagram Help Center: What is considered branded content and TikTok’s Branded Content Policy requires the commercial content disclosure toggle. Checked against TikTok: Branded Content Policy (published 4 August 2026, effective 31 August 2026)
Write the requirement into the brief, because FTC staff put the responsibility on both the influencer and the brand. Gift-only deals are covered in the nano influencer guide, and label wording in sponsored post meaning.
Are micro influencers better than macro influencers?
Neither is better across the board; they do different jobs. The IAB puts macro creators at 500,000 to 1 million followers, so one post goes to a far larger following, while a micro programme spreads the work across several smaller audiences. Checked against IAB: Creator Economy Ecosystem Mindmap (February 2025)Industry convention Choose macro for one big moment, and micro for several niches, more content to reuse and room to test. Our types of influencers guide lines up every tier, mid-tier included.
Micro influencer FAQ
What is a micro influencer?
A micro influencer is a creator whose following sits in the micro tier of an industry size convention. The IAB’s February 2025 creator economy map puts micro at 10,000 to 50,000 followers, between its Nano and Mid tiers. We found no platform or regulator that defines the tiers, and the label describes audience size, not niche, quality or price.
How many followers does a micro influencer have?
10,000 to 50,000 followers in the IAB’s bands. Other publishers draw the lines differently, so check which bands an agency, platform or report uses before you compare creators.
How much do micro influencers charge?
There is no official rate. Each creator sets a price, and the quote changes with the deliverables, ad rights, exclusivity and timing you ask for. On TikTok One, creators list an expected rate that advertisers can see, and YouTube Creator Partnerships lets creators set desired rates.
Are micro influencers better than macro influencers?
Not in general; they do different jobs. A macro creator, 500,000 to 1 million followers in the IAB’s bands, posts to a far larger following, while a micro programme spreads the work across several smaller audiences. Choose by the job, and measure each creator’s results instead of relying on benchmarks.
Do micro influencers have to disclose sponsored posts?
Yes. Disclosure rules don’t depend on follower count: the UK’s CMA says its guidance applies to anyone given free products or other incentives through their social media accounts, no matter how many followers they have, the FTC counts payment and free or discounted products as material connections to disclose, and Australia’s ACCC expects gifted posts to be disclosed too. FTC staff say it’s best to add your own disclosure even when a platform offers a label. This is regulator guidance, not legal advice.
