Ad disclosure for influencers: when 'Werbung' is mandatory

Few topics leave Creators as uncertain as ad disclosure. When does a post have to be marked as advertising, when is the Paid-Partnership label enough, and what happens if you get it wrong? This article brings order to the most important questions — clear, practical and tailored to the German fashion market in 2026. One thing up front, plain and honest: this is guidance, not legal advice. When in doubt and in specific individual cases, there is no way around a law firm specialised in competition law.

The good news: the basic rule is simpler than many think. Once you have understood it, you disclose confidently and routinely — and don't have to reconsider with every post. This very craft is part of a Creator's professional setup, and it is one of the areas where we closely support the talent at Gross Management.

Why disclosure is mandatory in the first place

Behind the disclosure requirement lies a simple idea: anyone reading a post should be able to tell whether it is an honest recommendation or paid advertising. Hidden advertising — known in legal jargon as "surreptitious advertising" — deceives the audience about the commercial intent. That is precisely what is not allowed.

In Germany, two sets of rules interlock here above all: the Act Against Unfair Competition (UWG), which requires the commercial purpose of a post to be transparent, and media law (the Interstate Media Treaty) with its fundamental requirement to separate advertising from editorial content. The platforms themselves — Instagram, TikTok, YouTube — also have their own guidelines. So you are operating within a web of law and platform rules. That sounds more complicated than it is in everyday life, because the practical consequence is usually the same: commercial posts must be clearly recognisable as such.

To be clear once more: which law applies how in a given case depends on details that keep shifting with new rulings. This overview does not replace a legal review — it is only meant to give you a reliable gut feeling for when you should take a closer look.

"Werbung", "Anzeige" or "paid partnership" — what counts?

This is where the wildest myths circulate. In fact, two terms have become firmly established as safe in German case law: "Werbung" (advertising) and "Anzeige" (advertisement). Both are unambiguous, German and leave no room for interpretation — which is why they count as the robust standard solution.

• "Werbung" / "Anzeige": The two classic terms accepted by the courts. Anyone who uses them is on the safe side.
• "Paid partnership" (Paid Partnership): The platform-side label that appears at the top of the post. It is sensible and important — but whether it always suffices on its own is assessed differently from a legal standpoint. Many professionals combine it with an additional plain-text disclosure.
• English terms like "Ad", "Sponsored", "Advertisement": Risky in a German-language post. For a predominantly German audience, the German disclosure is the safe choice.

What is not enough: creative paraphrases like "in friendly collaboration", a small "#ad" at the end of a mountain of hashtags, or the word "Werbung" hidden invisibly in the body text. The disclosure must be clear, unmistakable and recognisable at a glance — ideally at the start of the caption and not only after the "show more" cut-off.

The safest disclosure is the one nobody has to think about: in German, unmistakable, high up — and no hide-and-seek in the hashtag jungle.

Using platform tools correctly — and knowing their limits

Instagram, TikTok and YouTube offer their own advertising labels. They are useful, but they do not fully replace your own judgement.

The Paid-Partnership label

Via the branded content function you link the post to the Brand account; "Paid partnership with …" then appears at the top. The label creates transparency, gives the Brand insights and is technically necessary anyway for whitelisted Ads. You'll find more on the advertising re-use of your Content in our article on Whitelisting and Spark Ads.

Why the label alone often isn't enough

Three weak points you should be aware of. First: the label is linguistically controlled by the platform and isn't displayed equally prominently everywhere. Second: with Stories or certain formats it isn't always available. Third: courts have emphasised in the past that the disclosure must be unambiguous for the specific audience in question. That's why many experienced Creators run a two-track approach: the platform label plus a clear "Werbung" or "Anzeige" at the start of the caption. Belt-and-braces does no harm here — quite the opposite.

Gifts, affiliate and self-promotion — the grey area

The trickiest cases are rarely the clearly paid campaigns. They are the in-between shades. A rough orientation — deliberately worded with caution, because a lot depends on the details here:

• Products received for free (PR packages, gifts): Anyone who receives a product for free and shows it should, as a rule, disclose the post — even without any money changing hands. The consideration is the product itself.
• Affiliate links and discount codes: Here you earn a share of the sales. That is a commercial benefit — such posts should be marked, often with a note like "contains advertising / affiliate links".
• Your own products and self-promotion: If you advertise your own Brand, your shop or your merch, that is advertising too — even though the requirements for disclosure are often assessed differently in practice here than for third-party advertising.
• Self-bought products, honest recommendation, no benefit: If you paid for something out of your own pocket, tag no one for it and receive no consideration whatsoever, a lot speaks against a disclosure requirement. But: as soon as a link, a code or a cooperation is in the background, the assessment tips quickly.

Rule of thumb for your gut feeling: If there is any benefit — money, product, commission, reach deal — disclose when in doubt. One disclosure too many has never cost a Creator a warning letter. A missing one, on the other hand, certainly has.

Who is liable: Creator, Brand or both?

One of the most common questions — and one where many get it wrong. The reflex "the Brand is responsible, not me" isn't quite right. Simplified and without any claim to completeness:

• The Creator, as the person who publishes the post, is regularly exposed in their own right. A warning letter can land directly on you — regardless of what the contract says.
• The Brand can also bear responsibility, for instance as the commissioning party of the advertising. Frequently both sides are liable side by side.
• An agency can, depending on its role, share the obligation, but in practice it protects you above all by bringing clean processes and clear Briefings to the table.

In plain terms: you can't simply "delegate" responsibility to the Brand. That's why it pays to see your own disclosure as part of your own professionalism — not as a tiresome duty of the commissioning side. What a fair deal looks like and what else you should watch out for is something we go deeper into in the article Understanding the influencer contract.

Typical warning-letter traps

Most problems don't arise from bad intent, but from routine mistakes. The classics that cause trouble again and again:

1. Disclosure hidden in the hashtag block: A "#ad" among twenty other hashtags at the end is frequently considered not sufficiently clear.
2. Disclosure only after the "show more" cut-off: If you have to click further to see the marking, you don't recognise the advertising at a glance.
3. Stories without a visible label: Especially in fleeting Story frames, the disclosure is easily forgotten — yet the same standards apply here.
4. English terms for a German audience: "Sponsored" or "Ad" don't reliably replace the German "Werbung".
5. PR packages left unmarked "by accident": The gifted item is shown as a matter of course — without any note. One of the most common gaps of all.
6. Affiliate links without a note: The commission link in the profile or bio slips through the net because it doesn't look like "classic" advertising.

Strikingly often, objections don't come from authorities but from competitors or warning-letter associations. That makes the topic uncomfortably predictable: it rarely hits by chance, but regularly hits those who work sloppily.

Pinning down disclosure in the contract

Professionals settle disclosure not at the moment of posting but already in the contract. That protects both sides and prevents discussions shortly before go-live. Sensible points — as orientation, not as a finished clause:

• Which disclosure is used? Pin down the term ("Werbung" / "Anzeige"), the position (at the start of the caption) and the use of the platform label.
• Who bears which responsibility? Make clear that the Creator implements the disclosure and the Brand discloses the commercial character of the deal.
• Approval process: Does the Brand see the post including the disclosure before publication? That catches mistakes before they go public.
• Liability and indemnification: How are warning letters handled, especially when the Brand delivered a faulty Briefing? Here it pays to have a specialist take a look.

This is exactly where you notice the difference between going it alone and professional support. A good agency brings vetted contract building blocks, so you don't start from scratch with every deal. If you want to work at this level, this is a good moment to apply to Gross Management — we take care of Briefings, terms and framework conditions so you can concentrate on the Content.

Checklist per post

Before you tap "share", run through this short list. It doesn't replace a legal review, but it catches by far the most common mistakes:

1. Is there a benefit? Money, product, commission, discount code, trip, reach deal — if yes, on to point 2.
2. German plain-text note in place? "Werbung" or "Anzeige" — visible, not in the hashtag block.
3. Is the note high up? At the start of the caption, before the "show more" cut-off, in Stories as a text overlay or sticker.
4. Platform label activated? Paid Partnership / Branded Content set up where possible.
5. Does this apply to all formats too? Reel, Story, carousel, Pin — check every single asset, not just the main post.
6. When in doubt: disclose. The more expensive decision is almost always not to do it.

These six steps become routine with a little practice. Anyone who works cleanly from the start builds, almost as a by-product, a profile that Brands trust — and that's worth hard cash. How you build this profile systematically is something we show in How do I become an influencer.

Frequently asked questions about ad disclosure

Do I also have to disclose if I don't get paid?

In many cases, yes. As soon as you receive a benefit with monetary value — a free product, a PR package, a trip — a lot speaks for a disclosure, even without a fee. The consideration doesn't have to be money. This is guidance, not a binding statement for your individual case.

Is the Paid-Partnership label enough on its own?

It is important and sensible, but whether it always suffices on its own is judged differently from a legal standpoint. You're on the safe side with the combination of the platform label and a clear "Werbung" or "Anzeige" at the start of the caption.

What happens if I disclose incorrectly or not at all?

Possible consequences include warning letters — often from competitors or associations — with a cease-and-desist demand and cost implications. The exact consequences depend on the individual case. That alone is why it pays to disclose once too often rather than too rarely.

Does this also apply to Stories and affiliate links in the bio?

In principle, the same standards apply to all formats and placements. Stories need a visible note, and commission links in a bio or description should also be recognisable as advertising. Fleetingness doesn't protect you from the obligation.

How to work safely — and relaxed

From the outside, ad disclosure looks like a minefield, but in everyday life it is above all a question of good routines: disclose in German, place it high up, mark it when in doubt, and settle the framework conditions in the contract from the start. Anyone who internalises this posts more calmly and comes across to Brands as more professional — both of which pay directly into your career.
