Roles and players

Micro-influencer

Also called micro influencer, microinfluencer, nano-influencer.

Short answer

A micro-influencer is a content creator with a smaller but engaged following – most often defined as 10,000–100,000 followers, with nano-influencers below 10,000. In affiliate marketing micro-influencers are interesting because high credibility within a niche typically gives a higher conversion rate than broad reach.

Definition of Micro-influencer.

The thresholds vary from agency to agency, but a common breakdown is: nano-influencer 1,000–10,000 followers, micro-influencer 10,000–100,000, macro 100,000–1 million and mega above that. The follower count is, however, the least interesting number. The engagement rate – likes and comments relative to followers – usually falls as the account grows, and it is engagement that drives clicks and sales.

For affiliate marketing, micro-influencers are a natural match. A fixed fee per post is hard to justify when reach is limited, but commission per sale removes the risk for the store and gives the influencer ongoing income from content that already exists. An affiliate link in the bio, a discount code and links in Stories are the standard tools.

The strength lies in the niche. An account about sourdough baking with 15,000 followers reaches exactly the people who buy baking steels and grain mills – and the recommendation comes from someone the followers have followed for a long time. The mechanism is the same as on a niche site, just on social platforms, and it only holds as long as the recommendations are credible.

The rules: advertising must be disclosed

If a micro-influencer works with a store for commission, the content is advertising. In Denmark, the Marketing Practices Act and the Danish Consumer Ombudsman's guidelines require clear disclosure – 'Reklame' (advertisement) or 'Annonce' at the start of the post – also when payment is commission rather than a fixed fee. If the income becomes regular, questions of business registration, VAT and tax follow.

What the store should look for

Followers can be bought; engagement is harder to fake, but not impossible. Look for comments with substance rather than rows of emoji, an audience in the right country – a Danish store needs a Danish audience – and a history of collaborations that match the niche. 10 micro-influencers with 10,000 relevant followers each often beat one account with 100,000 mixed ones.

How it goes wrong

  • 01

    Reach mistaken for relevance

    An account with 80,000 followers spread across the world is worth less to a Danish store than 8,000 Danish followers in the target group. Check the audience's geography and language before agreeing to work together.

  • 02

    Missing advertising disclosure

    Commission is a commercial agreement, and posts without clear disclosure break the rules – in Denmark, the Marketing Practices Act. Responsibility falls on both parties – the advertiser shares responsibility for the influencer's posts being disclosed correctly.

  • 03

    Engagement can be bought

    Comment pods and bots can inflate the engagement rate. Read the comments: are they about the content, or are they generic? A high number without substance is a warning sign, not a selling point.

At Affilyflow

Micro-influencer in practice

A micro-influencer can sign up to Affilyflow as an affiliate and promote Danish stores' programs with links and discount codes. The commission is exactly the rate the program shows – the network fee is part of the store's total price – and rate and type are locked at the moment of the click, so clicks created by a post cannot be adjusted down afterwards.

Frequently asked questions

How many followers do you need to be a micro-influencer?

The most common breakdown says 10,000–100,000 followers, with nano-influencers from 1,000 to 10,000. The thresholds are not official and vary between platforms and agencies. In practice, engagement rate and the relevance of the niche matter more than the exact follower count.

Can you make money as a micro-influencer with affiliate links?

Yes. With commission per sale there is no minimum reach – income depends on how many followers click and buy. An account with 10,000 engaged followers in a high-spending niche can generate more sales than a much larger account with a broad audience.

Do micro-influencers have to disclose affiliate links as advertising?

Yes. Commission is a commercial agreement, and posts with affiliate links must be clearly disclosed as advertising – in Denmark under the Marketing Practices Act and the Danish Consumer Ombudsman's guidelines, typically with 'Reklame' (advertisement) at the start of the post. The requirement applies whether payment is a fixed fee or commission per sale.

What is the difference between a nano-influencer and a micro-influencer?

The split is by follower count: nano-influencers typically have 1,000–10,000 followers, micro-influencers 10,000–100,000. Nano accounts often have the highest engagement measured as a percentage, but less total reach. For affiliate collaborations both are interesting, because payment follows sales, not reach.
