Ad Disclosure in Influencer Marketing: What Brands Need to Know in 2026

Updated on 11 November 2026

When a sponsored post goes out without an advertising label, the criticism lands on the creator and on the brand behind it. The basic rule is simple. Gifted products, affiliate links and creators’ own brands are where it gets harder. Here is what to watch as the client.

It is a practical overview of the German market and does not replace legal advice.

The basic rule: anything in return makes it advertising

If a creator receives something from your brand for a post, the post has to be recognisable as advertising. Straight away, that is – before anyone has watched the video to the end or expanded the caption. And “something” covers more than a fee.

When a label is needed

Paid posts. The clear case: a fee in exchange for content. Always label.

Gifted products and benefits in kind. A free product, a trip, an event invitation or a loan item also counts as something in return. A post about it is advertising even if no money changed hands. If you send out products hoping for coverage, ask anyone who posts to label it.

Affiliate links and discount codes. If the creator earns on each sale, that is compensation too. The link or code should be recognisable as advertising, and so should the post around it.

The creator’s own brand. A creator presenting their own products or company is advertising as well. If it isn’t obvious at first glance that this is their own business, a label belongs there. This matters to you when you develop a product together or the creator holds a stake in your brand.

Bought themselves, nothing in return. When someone recommends a product they paid for and receives nothing from the brand, that is generally not advertising that needs a label. That can change once there is a business relationship with the brand. If in doubt, label.

What a proper label looks like

• Wording: “Werbung” or “Anzeige” for German-language content. Don’t rely on English shorthand such as #ad or #sponsored, or on phrases like “thanks to …”. For a German-speaking audience they are not clear enough.
• Position: at the start of the post, visible without tapping “more”. Not at the end, and not among the hashtags.
• Video: the label belongs in the video itself, shown or spoken at the beginning – not only in the description.
• Stories: label every story frame that contains advertising, not just the first. Many viewers join halfway through.
• Legibility: large enough, in contrast to the background, on screen long enough.

Platform labels: use them, but not on their own

Instagram, TikTok and YouTube each have a function that marks a post as a paid partnership. Use it. The platforms require it in their own rules for branded content. Depending on the platform, it is also what lets you view a post’s figures or promote it as an ad later.

It is not a substitute for the label in the post itself. Names and display differ from platform to platform, and they change. The safe route is both: the platform label plus “Werbung” or “Anzeige” in the post.

Who is responsible: brand or creator?

The creator publishes and has to label. That doesn’t let you off the hook. You commissioned the post, and a missing label can have consequences for your brand as well – legally, and certainly in terms of trust. So:

• Put the obligation in the contract and the exact form in the briefing. Our article on contract and briefing shows how the two work together.
• Check at approval that the label is there and in the right place.
• Look again after publication and ask for a correction immediately if anything is missing.

Never ask a creator to leave the label out “so it feels more natural”. Communities recognise advertising anyway.

Before you book someone, look at how they labelled past collaborations – one of the checks in our article on how to find influencers.

What applies to your own channels

If you post creator content on your brand’s channel or run it as an ad, the sender is your brand. The question then is less about disclosure and more about the rights to the material – typical for UGC marketing. If an ad runs under the creator’s name, it still has to be clear that a brand is behind it.

And if your campaign runs in several countries, check the rules for each market. Wording and requirements differ.

Disclosure checklist before publishing

• Is there anything given in return – fee, product, trip, invitation, commission?
• Does “Werbung” or “Anzeige” appear at the start of the post?
• Is the label visible or audible in the video itself?
• Is every story frame labelled?
• Is the platform label switched on and your brand linked correctly?
• Is the affiliate link or discount code recognisable as advertising?
• Are the obligation and the form set out in contract and briefing?
• Who checks the post after it goes live?
