Mandatory disclosures in influencer marketing: #ad, sponsorship labels, affiliate codes

An influencer publishes a sponsored video, activates the platform’s Paid partnership label and adds a discount code to the caption. Is that enough to meet influencer disclosure requirements? Not always.

Each disclosure method serves a different purpose. A clear label such as #Ad tells viewers directly that the content is advertising. A platform sponsorship label identifies a commercial relationship through the platform’s own system. An affiliate link or discount code helps track sales, but it may not clearly explain that the creator receives commission or another benefit.

Whether a disclosure is sufficient can also depend on the content format, where the disclosure appears, the platform being used and the countries targeted by the campaign. A label hidden at the end of a caption may be easy to miss. A disclosure placed only in a video description may not reach viewers who never open it.

For brands, agencies and influencers, the safest approach is to treat disclosure as a complete process. The commercial relationship should be explained clearly, placed where audiences will notice it and supported by the appropriate platform tools. The Famesters influencer marketing agency experts are here to explain and elaborate on mandatory disclosures.

What makes an influencer disclosure mandatory?

A disclosure is generally required when an influencer has a relationship with a brand that could affect how audiences interpret their recommendation. Regulators use different terms for this relationship. The FTC calls it a “material connection,” while UK advertising guidance commonly refers to a “commercial relationship” between the influencer and the brand.

The connection is not limited to a traditional sponsorship payment. It may include:

• A fixed fee for creating or publishing content.
• Free or discounted products and services.
• Affiliate commission.
• Free travel, accommodation or event access.
• Performance bonuses or other incentives.
• Employment, ownership or another business relationship.
• A personal or family relationship with the brand.

For example, a creator who receives a free product and later recommends it may still need to disclose the relationship, even if the brand did not pay for the post or require a positive review. FTC guidance specifically includes payments, free or discounted products, employment, and personal or family relationships as examples of material connections.

Affiliate marketing also creates a commercial relationship. When a creator can earn money from purchases made through a link or code, viewers should be able to understand that financial connection before acting on the recommendation. EU consumer guidance similarly identifies brand partnerships, content created in exchange for products or services, and affiliate marketing as advertising that must be disclosed.

Payment is not the only trigger

A common mistake is to assume that disclosure is unnecessary when no money changes hands. In practice, products, services, access, discounts and other benefits may all influence a creator’s content or the way viewers evaluate it.

The influencer’s opinion may be completely honest, but honesty does not remove the need for transparency.

Would the relationship affect audience perception?

A useful practical question is: would knowing about this relationship change how a reasonable viewer evaluates the recommendation? When the answer may be yes, the relationship should be disclosed clearly. Brands, agencies and creators should not assume that viewers already know about an existing partnership or can identify commercial content from context alone.

#Ad, sponsorship labels, and affiliate codes compared

Influencer campaigns often use several disclosure methods at the same time. Although they may look similar to viewers, they do not communicate the same information.

The FTC considers simple terms such as Ad, Advertisement and Sponsored understandable disclosure language. However, the disclosure must still be placed where viewers are likely to notice it. It should not be hidden at the end of a long caption or mixed into a group of hashtags and links.

A platform label serves a different purpose. For example, TikTok’s content disclosure setting can mark branded content as Paid partnership, while YouTube asks creators to declare videos that contain paid promotions. These tools help platforms identify commercial content, but creators and brands remain responsible for following applicable disclosure rules.

The FTC specifically warns that a built-in platform tool is not guaranteed to provide a clear and conspicuous disclosure by itself. Its effectiveness depends on factors such as placement, readability and whether ordinary viewers understand what the label means.

Affiliate codes are also different from disclosures. A personalised code may suggest that a relationship exists, but it may not tell viewers that the creator receives commission. When that financial benefit is not obvious, a clearer explanation should be added.

The practical conclusion is simple: #ad, platform labels and affiliate codes should not be treated as interchangeable. A campaign may need more than one of them to make the commercial relationship clear.

How to use #ad correctly

Adding #ad is not enough if viewers are unlikely to notice or understand it. The disclosure should appear close to the endorsement and before the audience clicks a link, buys a product or continues watching without realising that the content is advertising.

The US Federal Trade Commission’s guidance for social media influencers recommends placing the disclosure directly with the endorsement. It warns that disclosures may be missed when they appear only on a profile page, at the end of a post or behind a “more” button. The disclosure should also not be hidden among a large group of hashtags or links.

In practice, influencers should:

• Place Ad, Advertisement, Sponsored or #ad near the beginning of the content.
• Make the disclosure easy to read and difficult to miss.
• Use the same language as the endorsement.
• Include the disclosure inside a video rather than relying only on its description.
• Keep visual disclosures on screen long enough to be read.
• Use both spoken and visual disclosure when this helps viewers notice it.
• Repeat the disclosure during a livestream because viewers may join at different times.

These recommendations are set out in the FTC’s official guide, Disclosures 101 for Social Media Influencers. The guide identifies ad, advertisement and sponsored as examples of simple and understandable language. It also explains that using a hashtag such as #ad is acceptable, but the hashtag format itself is not mandatory.

Are #spon, #collab or “thanks” sufficient?

Abbreviated or vague language may not clearly tell viewers that the content is advertising. The FTC’s social media disclosure guidance advises against unclear terms such as sp, spon and collab, as well as standalone wording such as thanks or ambassador.

The problem is not the hashtag format itself. The problem is whether an ordinary viewer immediately understands the commercial nature of the content.

Does every country require the exact hashtag #ad?

No single disclosure format applies worldwide. Regulators may use different terminology and standards.

In the UK, Section 2 of the CAP Code requires marketing communications to be obviously identifiable as advertising. The ASA and CAP guidance on social media and influencer marketing states that the regulator is likely to expect a prominent Ad label upfront, usually at the beginning of the content, when the advertising nature of the post may not otherwise be clear.

Brands should therefore define disclosure wording according to the target market instead of automatically using the same label in every country.

Are platform sponsorship labels sufficient?

Platform labels such as Paid partnership or Includes paid promotion help audiences identify commercial content. They are also used by platforms to manage branded content, advertising permissions and transparency requirements. However, activating a platform label should not automatically be treated as full compliance with every applicable disclosure rule. The label may need to be supported by a clear disclosure inside the video, caption, Story or livestream.

The FTC’s official disclosure guidance specifically tells influencers not to assume that a platform’s disclosure tool is sufficient. The commercial relationship must still be communicated clearly in a place and format that viewers are likely to notice.

Instagram paid partnership labels

Meta requires influencers to use Instagram’s Paid partnership label when publishing branded content. Meta defines branded content as creator or publisher content that features or is influenced by a business partner in exchange for value. This may include products or services provided for free.

Instagram’s Paid partnership label identifies the relevant brand above the post. However, brands and creators should still check whether additional wording, such as Ad, is required by the regulations applying to the target audience.

TikTok content disclosure settings

TikTok requires influencers to activate its content disclosure setting when posting content that promotes a brand, product or service. The setting is intended to show viewers that the content is commercial in nature.

For branded content created on behalf of another business, TikTok applies the Paid partnership label. Content promoting the creator’s own business may receive a different promotional label. Using the setting is necessary for compliance with TikTok’s platform rules, but it does not remove the creator’s or advertiser’s responsibility to follow applicable advertising laws.

YouTube paid promotion declarations

YouTube requires influencers to inform the platform when a video contains paid product placements, sponsorships, endorsements or other commercial content that requires disclosure. Creators do this by selecting the paid promotion box in the video details.

YouTube may then show viewers a paid-promotion notice. However, YouTube also states that creators and brands remain responsible for following applicable legal and regulatory obligations. A YouTube creator should therefore not rely only on the automated notice. A sponsorship should normally be disclosed clearly in or near the sponsored segment, using spoken, written or on-screen wording appropriate to the content.

Platform rules and legal rules are not identical

Platform tools and legal disclosure requirements overlap, but they serve different systems.

A campaign may need to comply with:

• The platform’s branded-content policy.
• Advertising and consumer-protection rules in the target country.
• Disclosure obligations in the creator’s contract.
• Additional requirements established by the brand or agency.

The safest operational approach is to activate the required platform label and add a clear audience-facing disclosure where viewers will notice it. A platform setting should support the disclosure, not replace it. Also, you can learn more about global iGaming influencer compliance from our dedicated article.

Why affiliate codes are not always disclosures

Affiliate links and discount codes are common in influencer campaigns, but they do not necessarily explain the creator’s financial relationship with the brand.

A code such as JANE20 may show that the influencer is connected to the company and may give the customer a discount. However, it does not clearly tell the audience whether the creator receives a commission, a fixed payment or no financial benefit at all.

The FTC’s Endorsement Guides explain that the term affiliate link may not be sufficiently clear because some consumers may not understand that the creator receives payment when they use the link. The FTC suggests using wording that directly explains the financial relationship, such as stating that the creator receives commission from purchases.

The difference is important:

An affiliate link or code tracks traffic, attributes sales or provides a customer discount.

An affiliate disclosure tells the audience that the creator may benefit financially from the purchase.

Affiliate link versus affiliate disclosure

An influencer should not rely only on wording such as: Use my code JANE20 for 20% off.

A clearer version would be: Ad: I may earn a commission when you purchase through my link or use my code.

The wording must reflect the actual arrangement. A creator should not claim to earn commission if the campaign only includes a fixed sponsorship payment. In that case, a simple and accurate sponsorship disclosure may be more appropriate.

Where should affiliate disclosures appear?

The disclosure should appear before or close to the affiliate link, code or recommendation. It should not be hidden on a separate page, at the bottom of a long description or behind a link that viewers are unlikely to open.

For video content, the relationship may need to be disclosed inside the video as well as near the affiliate links in the description. The FTC’s guidance states that placing a disclosure only below a YouTube video may be insufficient because viewers may not open the description.

The practical rule is: tracking a sale is not the same as explaining who benefits from it. An affiliate link or code should be supported by clear language whenever the creator’s financial interest would not otherwise be obvious.

Disclosure placement by content format

A disclosure can use clear wording and still fail if it appears where viewers are unlikely to notice it. The correct placement depends on how people experience the content.

For visual posts, the disclosure should be visible without requiring viewers to expand a caption or visit another page. For video and audio content, it should form part of the content itself rather than appearing only in the description. During a livestream, it should be repeated because viewers may join after the first disclosure.

• TikTok requires creators to activate its content disclosure setting when publishing content that promotes a brand, product or service.
• YouTube requires creators to inform the platform when content includes paid product placements, sponsorships or endorsements. It also states that creators and brands remain responsible for complying with applicable local disclosure obligations.
• Meta’s Branded Content Policies require Instagram creators to use the Paid partnership label when publishing branded content.

The practical principle is consistent across formats: the disclosure should reach the audience at the same time as the endorsement, not after the viewer has already acted on it.

How disclosure rules differ across the US, UK, and EU

The basic principle is similar across major markets: audiences should be able to recognise advertising and understand the creator’s relationship with the brand. However, the exact terminology, legal framework and enforcement approach differ.

United States

In the US, influencer endorsements are regulated by the Federal Trade Commission under rules against deceptive advertising.

The FTC uses the term material connection for a relationship that may affect how consumers evaluate an endorsement. This can include payment, free or discounted products, employment, or personal and family relationships.

The connection should be disclosed clearly and in a place where viewers are likely to notice it. The FTC also states that influencers are responsible for understanding and making the required disclosures rather than relying entirely on the brand, agency or platform.

United Kingdom

In the UK, the Advertising Standards Authority enforces the advertising rules written by the Committee of Advertising Practice.

The CAP Code requires marketing communications to be obviously identifiable as advertising. Current ASA guidance states that labels such as Ad, Advert and Advertising are likely to be acceptable when they are clear and prominent.

An @mention, brand tag or vague reference to a partnership is not normally enough to identify a post as an advertisement. The ASA has repeatedly instructed brands and influencers to use clear labels such as #ad where the commercial nature of the content was not otherwise obvious.

European Union

EU consumer law requires commercial content to be disclosed. The European Commission specifically includes:

• Brand partnerships on social media.
• Content created in exchange for products or services.
• Affiliate marketing.

Influencers who regularly monetise their content may also be treated as traders under European consumer law and must follow the rules that apply to businesses interacting with consumers.

The European Commission’s Influencer Legal Hub provides EU-level guidance, including legal briefs on monetisation models and social media advertising disclosures.

However, EU-level rules are applied alongside national legislation, local regulatory guidance and advertising self-regulation. Brands should therefore check the rules in each EU country targeted by the campaign rather than treating the EU as one completely uniform disclosure market.

Who Is responsible for influencer disclosure compliance?

Disclosure compliance is not solely the creator’s responsibility. Depending on the jurisdiction and campaign structure, responsibility may extend to the brand, creator, agency or another intermediary involved in producing and distributing the content.

The UK Advertising Standards Authority also describes disclosure as a shared responsibility among influencers, brands, agencies and platforms.

Brand responsibilities

Under the FTC’s Endorsement Guides, advertisers should:

• Explain disclosure requirements to influencers.
• Provide guidance against misleading claims.
• Monitor creators’ compliance.
• Correct non-compliant content.
• Take steps to prevent the same problem from happening again.

An advertiser may be responsible for misleading influencer endorsements or for failing to disclose an unexpected material connection between the brand and creator.

Agency responsibilities

Agencies should turn regulatory and brand requirements into clear campaign instructions. This includes adding disclosure obligations to contracts and briefs, checking disclosures during content approval and reviewing the live post after publication.

The FTC states that intermediaries, including advertising and public relations agencies, may be responsible when they distribute endorsements they knew or should have known were deceptive. This may also apply when an agency hires or directs creators who fail to make necessary disclosures.

Influencer responsibilities

Influencers must accurately disclose their relationship with the brand and place the disclosure where audiences can notice it.

The FTC states that influencers are responsible for making disclosures, understanding the Endorsement Guides and complying with laws against deceptive advertising. Creators should not rely entirely on the brand, agency or platform to handle disclosure for them.

Platform responsibilities

Platforms provide branded-content labels, paid-promotion settings and policies for commercial content. These tools support transparency, but they do not automatically transfer responsibility away from the other campaign participants.

The safest process is to assign disclosure responsibilities before contracting, verify them during content approval and check the final published content. Contracts may allocate tasks between the parties, but they do not necessarily remove obligations imposed by applicable advertising rules.

Common influencer disclosure mistakes

Most disclosure problems are caused by unclear wording, poor placement or an assumption that another campaign participant has already handled compliance. Common mistakes include:

• Treating a discount code as a complete disclosure. A code may track purchases without explaining that the creator receives commission or another benefit.
• Placing #ad at the end of a long caption. Viewers may see the endorsement without expanding the post far enough to find the disclosure.
• Hiding the disclosure among hashtags or links. Advertising labels should be easy to identify rather than surrounded by unrelated information.
• Using vague wording such as “collab,” “partner,” “ambassador” or “thanks.” These terms do not always tell an ordinary viewer that the content is advertising.
• Relying only on a platform sponsorship label. A Paid partnership or paid-promotion notice may need to be supported by clear wording within the content.
• Disclosing only in a video description. Viewers may watch the endorsement without opening the description.
• Failing to disclose gifted products. A free or discounted product may create a material connection even when the creator receives no cash payment.
• Using a disclosure in the wrong language. The intended audience must be able to understand the wording immediately.
• Showing an on-screen disclosure too briefly. It should remain visible long enough for viewers to notice and read it.
• Disclosing only once during a livestream. Viewers who join later may never see or hear the original disclosure.
• Using the same instructions in every country. Disclosure wording and placement expectations vary across jurisdictions.
• Checking the draft but not the published post. Captions, labels or on-screen text may be changed during publication.

The FTC’s official influencer guide addresses unclear wording, hidden placement, video disclosures and livestream repetition. The UK’s ASA/CAP influencer guidance also stresses that advertising must be identifiable without requiring audiences to understand an influencer’s existing relationship with a brand.

These mistakes create more than regulatory risk. When audiences discover a commercial relationship only after clicking or purchasing, they may also lose trust in the creator and brand.

Influencer disclosure checklist for brands and agencies

Disclosure compliance should be built into the campaign process before content is created. A clear workflow reduces the risk of missing labels, inaccurate wording or last-minute publication delays.

Before contracting

• Identify every form of creator compensation, including fees, free products, discounts, travel and affiliate commission.
• Confirm the countries and audiences targeted by the campaign.
• Check which regulatory and platform requirements apply.
• Define which party is responsible for adding and checking disclosures.
• Include disclosure obligations in the creator agreement.
• Specify that the disclosure must remain in the published content.

During campaign briefing

• Provide the exact disclosure wording the creator should use.
• Explain where the disclosure must appear.
• State whether spoken, written and on-screen disclosures are required.
• Specify which platform-native labels must be activated.
• Explain the creator’s financial relationship accurately.
• Include examples of wording that should not be used.
• Clarify whether the disclosure must be repeated across multiple Story frames or during a livestream.

During content approval

• Check that the disclosure appears before or close to the endorsement.
• Review the first seconds, frames or lines of the content.
• Confirm that on-screen text is large enough to read.
• Check that the disclosure remains visible for long enough.
• Review spoken disclosures for clarity.
• Confirm that affiliate links and codes include an accurate explanation of the financial relationship.
• Verify that the required platform settings are included in the publication instructions.
• Check that the wording is understandable to the target audience.

After publication

• Review the live content rather than relying only on the approved draft.
• Confirm that the caption, video and platform label were published correctly.
• Check whether links and affiliate disclosures appear in the agreed location.
• Save screenshots or other evidence of the published disclosure.
• Request an immediate correction if anything is missing or unclear.
• Monitor edited captions, reposts and reuploaded content.
• Record recurring mistakes and update future briefs accordingly.

The most reliable process is simple: define the disclosure before contracting, verify it during approval and check it again after publication.
