Influencer Marketing Disclosure Rules in Denmark and the EU

Short answer: yes, if there's a benefit — and it has to come first

Hidden advertising is banned in Denmark. The rule sits in Markedsføringsloven § 6(4) (the Danish Marketing Practices Act), which Denmark's consumer ombudsman, Forbrugerombudsmanden, states plainly: "the commercial intent of any form of business practice, including advertising, must be clearly disclosed." In practice, that means the audience has to see it before they start reading or watching — not buried in a caption, not left as a hashtag at the bottom.

The rule applies whether the influencer received money, a free product, commission through a link, or simply a loan of clothing. EU consumer law — the Unfair Commercial Practices Directive — sets the same baseline across the whole EU, so a Danish influencer with an international audience is covered twice, not by whichever is more convenient.

For how this disclosure duty fits into the wider Danish market — market size, who actually follows influencers, and what enforcement looks like beyond this article — see what does the Danish influencer marketing market look like?

What actually triggers the disclosure duty?

What matters is not whether a written agreement exists. What matters is whether the influencer received a benefit in exchange for the mention. Forbrugerombudsmanden is explicit on this: it counts as advertising if an influencer receives a gift in exchange for mentioning the company or product — regardless of whether they were asked to mention it.

Note that commission and affiliate links sit on exactly the same line as a paid partnership. The distinction between influencer marketing and affiliate marketing is about relationship and curation — not about whether the disclosure duty applies. It applies to both. The "event invitation" row also covers press trips and PR unboxing packages — see event activations, press trips and unboxing for how those three in-person formats should actually be briefed and disclosed.

How to disclose correctly, per Forbrugerombudsmanden

Forbrugerombudsmanden's guidance on advertising identification sets specific requirements, and they're stricter than most influencers assume:

• Write "reklame for [company]" or "annonce for [company]" as the first element of the post — not in the middle, not at the end.
• Mark every post individually. Marking the first post in a series and assuming the rest are covered is not enough.
• Use text in a size and colour that doesn't blend into the background — the disclosure has to be readable without effort.
• For video, the disclosure must appear in the title or be visible in the opening frames — not hidden in a description no one opens.
• For links: write "reklamelink" ("ad link") directly above or beside the link, every time it's used.

What is NOT enough

• A hashtag alone, such as #ad or #sponsored, with no other marking
• Disclosure placed only at the end of a long caption
• Marking the first post in a series and leaving the rest unmarked
• Relying solely on the platform's built-in label (e.g. Instagram's "Paid partnership") without the creator's own disclosure

That last point catches a lot of people out. The platform's own tool is a support, not a substitute for the influencer's own disclosure — Forbrugerombudsmanden deliberately treats them as two separate things.

A stricter standard for content aimed at children

There is a heightened clarity requirement when advertising targets recipients under 18. The more vulnerable the audience is to commercial influence, the less room there is for ambiguity about what's an ad. Three industries — alcohol, finance and pharma — carry additional legal restrictions on top of this disclosure duty; see influencer marketing in regulated industries: alcohol, finance and pharma in Denmark for what changes. Beyond disclosure, a separate set of rules governs marketing aimed at children and young people specifically — dangerous-behaviour content, profiles belonging to under-15s, and an absolute ban on urging children to buy — see marketing to children and teenagers through influencers: what Danish law actually requires for the full framework, including who besides the influencer can be held liable.

The EU rules: the Unfair Commercial Practices Directive

At EU level, influencer marketing is governed by the Unfair Commercial Practices Directive (UCPD), the core consumer protection law across the single market. Article 7(2) of the directive treats a failure to disclose the commercial intent behind a practice as a misleading omission. The European Commission classifies influencers who conduct commercial activity — promoting brands and receiving compensation — as "traders" under the directive, which means they're subject to the same transparency requirements as any other advertiser.

The European Commission's Influencer Legal Hub spells the requirement out further: disclosure must be clear, unambiguous and easily visible, and it must be apparent before the audience engages with the content — the same principle as the Danish rule that disclosure has to come first. The requirement applies across every platform and all three common monetisation models: paid partnerships, gifted products and affiliate marketing.

How badly is compliance actually failing?

On 14 February 2024, the European Commission and consumer authorities from 22 EU countries published the results of a joint sweep of 576 influencers' social media posts. The findings: 97% of the influencers had posted commercial content, but only around 20% disclosed it systematically as advertising. 38% failed to use the platforms' own labels (such as Instagram's "Paid partnership") and instead used vague wording like "collaboration," "partnership," or a general thank-you to the brand. 358 influencers were flagged for further investigation by national authorities.

The numbers aren't unique to one country. The European Commission's Influencer Legal Hub highlights, among other findings, a Spanish market review in which 77.75% of the content reviewed did not meet disclosure requirements.

The Digital Services Act: the platform's role

Since the Digital Services Act (DSA) took effect on 17 February 2024, large platforms (Article 26) must give users — including influencers — a way to declare that a post contains commercial communication, and the platform must then make that clearly recognisable to other users in real time. It's worth being precise here: the DSA obliges the platform to provide the tool. The underlying legal duty to disclose still sits with the influencer and the brand, grounded in the UCPD and national law like Markedsføringsloven — not in the DSA itself. That specific requirement is Article 26(2) — once a post is whitelisted and run as a paid ad, a separate, stricter layer of DSA rules applies, covering who paid for it and how long it stays publicly searchable; see the EU DSA's ad transparency rules and what they mean for influencer marketing for what changes once that happens.

Coming rules: the Digital Fairness Act (a proposal, not yet law)

The European Commission's 2026 work programme includes a Digital Fairness Act, expected as a legislative proposal in 2026. The initiative explicitly names hidden advertising by influencers and the promotion of potentially harmful products (such as dietary supplements or cosmetic procedures) among the problems it aims to address.

It's important to be precise about status: this is a proposal, not current law, with no draft legal text published yet. For the full history of the initiative, the complete timeline, and a side-by-side look at what could change for disclosure versus what already applies today, see the EU Digital Fairness Act: what a proposed law could mean for influencer marketing disclosure. Until it becomes law, it's Markedsføringsloven and the UCPD that apply — the Digital Fairness Act is something to watch, not something to comply with today.

Decision framework: does this specific post need to be marked?

IF the influencer received money, product, commission or anything else of value in connection with the post → mark it, whether or not a written agreement exists.

IF the product was bought at full price with no agreement or expectation of a mention → no disclosure duty, but be careful if the brand sent the product unsolicited anyway.

IF the post contains an affiliate link or discount code the influencer earns from → mark it as an ad link, regardless of whether a separate fee was also paid.

IF the content is part of a series (multiple stories, multiple posts) → mark every single one, not just the first.

IF the audience includes recipients under 18 → use the clearest, most unambiguous disclosure, not the bare minimum.

Make Influence's recommendation for brands and creators

In our experience, most disclosure mistakes aren't a deliberate attempt to hide anything — they happen because neither side explicitly discussed it before the post went live. We recommend treating ad disclosure as a standing item in the pre-collaboration expectations conversation — alongside deliverables, timing and usage rights — rather than something the influencer is left to remember afterwards. Write the exact wording into the brief itself, not just the requirement to disclose.

The same applies when part of the deal is a hybrid arrangement with both an upfront fee and commission: the commission component triggers the disclosure duty just as reliably as the fee does, and it's easy to overlook if only the fee gets labelled "the payment."

Finally: correct disclosure doesn't cost performance. A post that clearly states "ad for [brand]" up front converts on the quality of the content, not on whether the audience discovers later that it was paid. The alternative — getting caught in a hidden-advertising case — costs both trust and, eventually, a name in one of Forbrugerombudsmanden's press releases.

FAQ

Do I need to disclose a post if I only got the product for free — no payment?

Yes. Forbrugerombudsmanden is explicit: a free product received in exchange for a mention is a benefit, and it triggers the disclosure duty the same way payment does.

Is a hashtag like #ad or #sponsored enough?

Not on its own. Hashtags don't count as sufficient disclosure unless they're accompanied by a clear disclosure as the first thing the audience sees — for example, "ad for [brand]" at the top of the post.

Who is responsible — the influencer or the brand?

Both can be held responsible. If the influencer operates as a business, they're independently responsible for their own marketing, and the brand can simultaneously be responsible as the party that commissioned the advertising.

What if an agency or manager writes the caption instead of the influencer?

Outsourcing who physically types the words doesn't change who's responsible for disclosure — the duty follows the commercial relationship (the benefit and who commissioned the promotion), not authorship. See ghost-posted influencer content: who's actually responsible for disclosure for how that plays out across three common outsourcing setups, and why "the agency wrote it" isn't a defence for either side.

Do the rules also apply to Stories, TikTok and YouTube — not just feed posts?

Yes. The prohibition on hidden advertising applies across all media and platforms. The practical requirements for how the disclosure should look are adapted to the format — for example, video must be marked in the title or in the first visible frames.

Is the platform's own "Paid partnership" label enough by itself?

Not automatically, according to Forbrugerombudsmanden. It should be supplemented with the influencer's own clear disclosure, because platform labels have historically proven easy to overlook or skip. For how to actually turn that label on for each platform — and how it connects to running ads from the creator's own account — see Meta's Paid Partnership label vs TikTok's Branded Content toggle, explained.

Are new EU rules coming that I should watch for?

Yes, but they aren't in force yet. The Digital Fairness Act is a proposal in the European Commission's 2026 work programme, expected to be tabled in 2026, with no draft text published yet and binding national implementation realistically years away. See the EU Digital Fairness Act: what a proposed law could mean for influencer marketing disclosure for the full timeline and status.

Do these same rules apply to employees posting about their own employer?

Not identically — there's no specific Danish guidance for that yet. See employee advocacy vs influencer marketing for how the disclosure logic differs for an employment relationship versus an external, paid collaboration.

Is this the same thing as GDPR?

No. This article covers ad-disclosure law — whether a post has to be labelled as advertising. GDPR is a separate law about how personal data is collected, stored and used, and it applies independently, whether or not a post is correctly disclosed. See influencer marketing and GDPR: what brands need to know for what that covers.

Do AI or virtual influencers need to disclose too?

Yes — and from 2 August 2026 there's a second, separate EU rule to know alongside this one. See AI and virtual influencers vs human creators for how the EU AI Act's new labelling duty stacks on top of the ad-disclosure rules covered here.

Does a giveaway or contest need extra disclosure beyond a normal paid post?

A chance to win a prize is itself a benefit that triggers the same disclosure duty covered above. Running a giveaway also brings in rules this article doesn't cover — Denmark's spam ban on entry requirements like tagging a friend, and sometimes a separate Danish prize tax — see how to run an influencer giveaway or contest, legally.

Does recommending a Buy Now, Pay Later (BNPL) option need anything beyond the ad-disclosure duty covered here?

Yes, potentially. If the post also makes a numerical claim about the cost of credit — "interest-free," "0 kr in fees," "split into 4" — a separate rule under Markedsføringsloven § 18 can apply on top of the ad-disclosure duty covered in this article, and BNPL is formally becoming regulated consumer credit under EU and Danish law from 20 November 2026. See BNPL in influencer marketing: what the EU's consumer credit rules mean from 2026 for the full walkthrough.

Does an environmental or sustainability claim need anything on top of this disclosure duty?

Yes — a separate documentation requirement applies to claims like "sustainable" or "climate-friendly," and from 27 September 2026 a defined set of green claims become automatically misleading under Danish law. See environmental and sustainability claims in influencer marketing: what Danish law requires for what changes.

If a post is correctly disclosed as an ad, can it still say anything it wants?

No. Disclosure and documentation are two separate duties. A correctly disclosed post can still contain a factual claim — an effect, a result, a comparison — that the brand can't back up, and that claim is governed by a different rule: the documentation requirement. See using influencer content as a testimonial: what Danish law requires you to document for what has to be documentable, especially once a brand reuses the post as its own testimonial.

What if two brands are named in the same disclosed post?

The disclosure duty doesn't change, but it does need to cover both commercial relationships, not just one. Forbrugerombudsmanden's own guidance is written around a single relationship at a time and doesn't explicitly address a post naming two brands. See brand-to-brand co-marketing through a shared influencer for how Make Influence recommends handling disclosure — and the rest of the deal — when two non-competing brands share one creator.

Does this article cover Sweden, Norway or Finland too?

No — this article is Denmark- and EU-specific. Disclosure wording, the regulator and the enforcement route all differ once you leave Denmark; see running an influencer campaign across the Nordics for a country-by-country comparison covering Denmark, Sweden, Norway and Finland.

Does a Danish influencer working with a US brand need to worry about US disclosure rules too, on top of everything above?

Potentially, yes — the US Federal Trade Commission's own Endorsement Guides can apply if it's reasonably foreseeable that the post reaches US consumers, regardless of where the influencer is based, though real enforcement risk against a single foreign creator is a separate, much smaller question from the legal one. See do FTC disclosure rules apply to a Danish influencer working with a US brand? for how the two rulebooks stack.

Does this disclosure duty also cover retouched or heavily edited body images?

No — those are two separate questions. This article covers whether content has to be marked as an ad at all; a specific duty to mark that an image has been retouched (body shape, size or skin) is a different rule, and as of writing Denmark doesn't have one — a bill requiring it has been proposed and dropped twice, most recently in December 2024. See Denmark's retouched-image labeling bill: why it's still not law in 2026 for the full status.

Does promoting a cryptocurrency or token need anything beyond this ad-disclosure duty?

Yes, potentially two extra layers. If the post recommends buying or selling a specific token, Article 20 of the EU's Market Abuse Regulation can apply on top of ordinary ad disclosure (see influencer marketing in regulated industries), and if the post promotes a specific crypto-asset on behalf of its issuer, the EU's MiCA regulation sets its own separate marketing-communication rules. See crypto and token promotions by influencers under MiCA for both.

Does an AI chatbot that replies to a follower's DM on a creator's behalf need to be disclosed as an ad?

That's a different duty from the one this article covers. Meta's own Creator AI feature automatically and permanently labels every response as AI-generated — but that label only tells the follower they're talking to an AI, not whether the underlying content or partnership is a paid ad. If the DM reply itself promotes a product under a paid deal, the ordinary disclosure duty covered in this article still applies in full, regardless of whether a human or an AI sent the reply. See Meta AI Studio: Creator AI personas explained for the full breakdown of that separate feature.

Does the UK have similar disclosure rules to Denmark's?

No — the UK is outside the scope of this article's Danish/EU law and runs its own, separate system: the ASA's CAP Code, with its own approved labels and, since 6 April 2025, a new direct fining power (up to 10% of global turnover) held by the UK's competition regulator, the CMA. See the UK's ASA/CAP Code vs Denmark's influencer disclosure rules, compared for the full breakdown.

Does this disclosure duty also cover paid political advertising?

Not exactly — it's a related but separate rule. A political ad also has to be disclosed as commercial content under this article's duty, but from 10 October 2025 it additionally falls under the EU's TTPA regulation, which requires its own transparency notice naming the sponsor, the amount paid, and the election or issue involved. See the EU's political advertising transparency regulation (TTPA) and what it means for influencer content for when that extra layer applies.

Does the Instagram Collab tag satisfy this disclosure duty on its own?

No. The Collab tag is a publishing feature that shares authorship and engagement across profiles — it says nothing about payment and doesn't switch on Meta's Paid Partnership label. If a Collab post is also a paid or gifted collaboration, the ordinary disclosure duty covered in this article still applies in full, on top of the Collab tag. See Instagram's Collab tag explained for the full mechanics.

Does a dietary supplement need anything beyond this ad-disclosure duty?

Yes, a separate and entirely independent rulebook. Even a correctly disclosed, clearly labelled ad for a dietary supplement still has to stick to the EU's Nutrition and Health Claims Regulation on what it can actually say about the product's health effects — disclosure and claims-compliance are two different duties that both have to be satisfied. See dietary supplements and influencer marketing: what Danish food-advertising law requires for what that separate regime bans, including in an influencer's own spoken testimonial.

Does correctly disclosing a post as an ad also guarantee the offer described inside it is truthful?

No — those are two separate duties. A correctly disclosed post can still make a misleading price or exclusivity claim, which is governed by an entirely different rule. See Forbrugerombudsmanden's "ja tak" offer ruling for a live 2026 example of a comment-to-claim offer found to raise exactly this issue.

Does a public body — a municipality or government agency — face anything beyond this disclosure duty when it buys an influencer campaign?

Yes, a completely separate question: Danish and EU public-procurement law can require the purchase to be put out to tender once its value crosses a threshold, regardless of whether the resulting content is correctly disclosed as an ad. See does a Danish municipality have to tender an influencer campaign? for the thresholds and what applies below them.

Is a competitor comparison ("X vs Y") covered by this same disclosure duty?

Not exactly — they're two different duties that can both apply to the same post. This article covers whether the post has to be marked as an ad at all. A separate rule, § 21 of markedsføringsloven, governs whether a comparison with a named competitor is fair and documented. See when does an influencer's "X vs Y" comparison count as comparative advertising under Danish law? for that rule.

Is a review that looks independent and unpaid — not a known sponsored post — covered by this same disclosure duty?

Yes, and it's worth treating as its own case. This article covers a post everyone already knows is a collaboration; a separate pattern is content built to look like an independent, unprompted review while actually carrying a commercial benefit — Forbrugerombudsmanden has ruled against exactly that in both a paid-traffic review-portal case and a "we tested it" claim that wasn't true. See when is an "organic" review actually hidden advertising under Danish law? for both rulings and the practical test.

Does a paid podcast guest appearance need to be disclosed the same way as a sponsored ad segment?

Yes — the same underlying disclosure duty applies whether the payment went to the show for an ad segment or to the show for a guest's seat in the conversation; only the format differs. See paid podcast guest appearances vs. sponsored episodes for how that specific, reversed-payment format works and what real prices look like.

Is a review posted on Trustpilot covered by this same disclosure duty?

The duty in this article still applies if there's a commercial benefit behind the review, but Trustpilot layers its own, stricter platform rule on top: an incentivized reviewer isn't eligible to write the review at all, disclosure or not. See incentivized and sponsored reviews on Trustpilot for how the two rulebooks differ.

Does a compliance audit after publication add anything beyond this disclosure duty?

Yes — a separate, practical layer. This article covers the legal requirement itself; a brand still needs its own process for checking that a specific published post actually met it, since a correctly agreed disclosure can be dropped in a later edit or lost when a platform's tag resets. See post-publication compliance audits for the checklist and cadence Make Influence recommends.

Does disclosure carry over when someone else Duets, Stitches or remixes a sponsored post?

That's not addressed by either platform's own documentation, and it's a separate question from the general disclosure duty covered above. See Duet, Stitch and Remix rights: who controls a derivative video built on sponsored content for Make Influence's operational reading of how the principle applies to a derivative video.

Does a paid "de-influencing" post that tells people not to buy something still count as an ad?

Yes. The disclosure duty depends on the commercial relationship, not on whether the message recommends buying or not buying. See de-influencing: what it means for brands when creators tell followers not to buy for how disclosure and comparative-advertising rules both apply to this newer content format.

Are fake or manipulated reviews covered by this same disclosure duty?

No, they're a separate legal question. This article covers whether content has to be marked as an ad at all. A separate EU rule — the Omnibus Directive's ban on submitting or commissioning false consumer reviews, or misrepresenting reviews and social media endorsements — governs whether a review's content is genuine, regardless of correct disclosure. See fake and manipulated reviews: what the EU Omnibus Directive bans for that rule, including a real Danish court case.

Can a video already earning platform ad revenue still need to disclose a sponsorship or affiliate link?

Yes — the two are unrelated. Platform ad revenue (such as YouTube's Partner Program) isn't advertising for a specific third party and needs no disclosure, but a brand deal or affiliate commission on the very same video are separate commercial relationships, and each still triggers the disclosure duty covered in this article. See ad revenue, brand deal and affiliate commission on the same video for how the three income layers stack, and which of them actually require disclosure.

Is a shoutout-for-shoutout between two influencers covered by this same disclosure duty?

There's no Forbrugerombudsmanden ruling on this exact scenario yet, but the same underlying test applies: what matters is whether a benefit was received in exchange for a mention, not specifically whether it was money or product. A reciprocal, agreed exposure exchange between two influencers can reasonably count as that benefit. See shoutout-for-shoutout: does a reciprocal cross-promotion between influencers need to be disclosed? for Make Influence's own reasoned application of this test to that scenario.
