In short
Ad disclosure means clearly labelling content that is paid for or influenced by any consideration. In Germany the UWG (§5a) and the Media State Treaty require clear German terms such as "Werbung" or "Anzeige" — visible and at the start of the post. Violations can trigger cease-and-desist letters and fines up to €500,000.
What is ad disclosure?
Ad disclosure is the obligation to make commercial communication recognisable as such. The underlying principle is separation and recognisability: viewers must immediately be able to tell whether content is an editorial or private opinion or advertising. Hidden advertising — so-called surreptitious advertising — is prohibited because it deceives the audience about the commercial nature.
For influencers this means: as soon as a post, reel, story frame or video is influenced by a consideration, that commercial intent must be disclosed. Consideration is interpreted broadly — money, free products, trips, discounts or commissions all count.
When must you label content as advertising?
The decisive question is not "is this a brand post?" but "is there consideration or a commercial purpose?". Since the 2022 UWG reform it is clarified: someone who receives no payment or comparable consideration for a mention generally does not act as commercial communication — genuine private enthusiasm then needs no label. In practice, the burden of proof and interpretation remain delicate.
| Situation | Disclose? |
|---|---|
| Paid collaboration (money) | Yes, always |
| Free product / PR sample received | Yes |
| Affiliate link / commission | Yes |
| Discount code with payment | Yes |
| Own product / own brand | Yes (self-promotion) |
| Self-bought product, no consideration, genuine private opinion | Usually no |
When in doubt, disclose
If the situation is unclear, disclosure is the lower risk. An extra label is not actionable; a missing one is.
How do you disclose correctly?
Regulators and the courts require disclosure that is clear, distinct and recognisable at first glance. Three criteria matter: the right term, the right placement and the German language.
- Term: "Werbung" or "Anzeige" are considered safe. Platform tools like "paid partnership" can supplement but do not replace clear self-disclosure in every case.
- Placement: at the start of the post — not hidden at the end, not behind "see more", not buried in hashtags.
- Visibility: readable contrast; in videos and stories also spoken or as on-screen text for the relevant duration.
- Language: in German when the content targets a German audience.
Which laws and authorities apply in Germany?
Several frameworks apply in parallel. The UWG protects against unfair competition, the Media State Treaty (MStV) governs the separation of advertising and content for telemedia, and the Telemedia Act adds provider duties. Practical guidance comes from the state media authorities — notably the joint guide of the Medienanstalten on social-media ad disclosure (led among others by Medienanstalt NRW).
| Framework | What it governs |
|---|---|
| UWG §5a(4) | Commercial purpose must be made recognisable; disguised advertising is unfair |
| Media State Treaty (MStV) | Advertising must be clearly recognisable and separated from other content |
| Medienanstalten guide | Practical FAQ: terms, placement, social-media examples |
What happens if you violate the rules?
Missing or insufficient disclosure can go two ways: a competition-law cease-and-desist letter (often from associations or competitors, with a cease-and-desist declaration and cost risk) or an administrative fine procedure by the state media authority. Fines can reach €500,000. More in the spoke on consequences and fines.
Who is liable — brand or influencer?
Both. The creator is liable as the direct actor; the brand can be jointly liable as the client. Clear contractual requirements and documented collaborations reduce the risk for both sides. More in the liability spoke.
Are "ad" and "sponsored" enough?
For a German audience, English abbreviations like "ad", "#ad" or "sponsored" are generally considered insufficient because not every user reads them as an advertising note. The German terms "Werbung" or "Anzeige" are safer. Details in the dedicated spoke.
How does a collaboration platform help?
Disclosure itself remains the creator's job. But a platform like Collavo documents the commercial relationship cleanly: brief, sealed contract and negotiation ledger keep the consideration and terms traceable — a solid basis if disclosure duty or liability is later questioned. It is explicitly not a guarantee of legal compliance.

Frequently asked
- Do I have to disclose free products?
- Yes. A free product or PR sample counts as consideration. Once the mention is influenced by it, disclosure is required.
- Is a #ad hashtag at the end enough?
- Usually no. Disclosure must be recognisable at first glance. Hidden at the end or buried in hashtags, it is often deemed not clear enough.
- Is this legal advice?
- No. This guide gives general orientation (as of June 2026) and does not replace individual legal advice.
