Influencer marketing disclosure is not optional, negotiable, or a technicality. It is a legal requirement in the US, UK, EU, and most major markets — and both brands and creators can face penalties for non-compliance. The rules have also evolved significantly: what was considered acceptable disclosure in 2018 is no longer sufficient under current FTC and ASA guidance. This guide covers the current state of disclosure requirements, what they mean for brands running creator campaigns, and how to build compliance into your campaign structure from the start.
Why Disclosure Rules Apply to Brands
The most important thing brands need to understand about influencer marketing disclosure is that the legal responsibility does not rest solely with the creator. Regulators on both sides of the Atlantic have clarified that brands are responsible for ensuring the campaigns they fund are properly disclosed — and can face enforcement action even when the creator published the non-compliant content without the brand's explicit instructions.
The FTC's 2023 updated Endorsement Guides make this explicit: "Marketers should advise their endorsers about their disclosure obligations and should monitor their endorsers' posts." An agency or brand that briefs creators without including clear disclosure requirements, or that fails to check that creators are disclosing properly, is in a precarious legal position regardless of whether the creator was aware of their obligations.
Brands are legally responsible for ensuring their creator campaigns are properly disclosed — not just the creators. Include disclosure requirements in every brief and audit published content for compliance.
FTC Guidelines: What the US Requires
The Federal Trade Commission's Endorsement Guides govern influencer marketing disclosure in the United States. The core principle is that any material connection between a brand and a creator — meaning any connection that might affect how viewers evaluate the endorsement — must be clearly and conspicuously disclosed. Material connections include: payment for the post, free or discounted products, affiliate or commission arrangements, employment relationships, and close personal or family relationships with the brand.
The FTC's "clear and conspicuous" standard means the disclosure must be: easy for viewers to notice, easy to understand, and presented before viewers engage with the content (so they can factor it into how they interpret the endorsement). For video content, a verbal disclosure at the beginning of the video and text on screen are both required — a disclosure at the very end of a long video does not meet the "conspicuous" standard. For written posts, the disclosure must appear in the first line of the caption, before any "see more" break.
Acceptable FTC disclosure language includes: "Ad", "#ad", "Sponsored", "#sponsored", "Paid promotion", or "I got this product for free to try." Ambiguous terms that do not clearly signal a commercial relationship — such as "#collab", "#partner", "#gifted", "#ambassador" — are not sufficient under current FTC guidance. The FTC has specifically noted that some viewers do not understand the advertising intent of hashtags like "#partner", so explicit ad language is required.
ASA Rules: What the UK Requires
The UK's Advertising Standards Authority and the CAP Code govern influencer marketing disclosure in the United Kingdom. The ASA's position is even more explicit than the FTC's on required language: the word "Ad" or "#Ad" must appear prominently in the post. "Gifted", "#gifted", "#gifted ad", "#spon", or "#collab" are not acceptable substitutes for "Ad" — the ASA has ruled against numerous posts using these terms alone.
The ASA's guidance distinguishes between fully paid posts (require "Ad" disclosure), gifted/seeded content where no payment was made but product was provided free (still requires disclosure in most cases — the ASA considers even free product a material connection if the brand had editorial control or approval rights), and genuinely organic mentions where no commercial relationship exists (no disclosure required). The middle category — gifted content — is where most brands inadvertently create compliance issues, because many assume that gifted content without payment does not need disclosure.
In the UK, gifted products still require "Ad" disclosure in most cases. The ASA considers free product a material connection — the absence of payment does not remove the disclosure obligation.
Platform Rules: TikTok and Instagram
TikTok and Instagram both have built-in branded content tools that add a "Paid partnership" or "Promotional content" label to posts when activated. These platform labels count as disclosure under most regulatory frameworks — but they are not a complete substitute for the text-based disclosures required by the FTC and ASA. Best practice is to use both: the platform's branded content toggle and explicit text disclosure ("#ad" in the caption or verbal disclosure in the video).
TikTok's Branded Content Policy requires creators to turn on the branded content toggle for any content that promotes a brand or product in exchange for payment or free goods. TikTok can remove content that appears to be branded content without the proper label — including content from accounts that have a history of non-disclosure. For brands running TikTok Shop affiliate campaigns, the platform automatically adds a disclosure label when affiliate links are included, but creators should still use explicit text disclosure as additional compliance coverage.
Building Compliance into Your Campaign Brief
The most effective way to ensure creator campaign compliance is to make disclosure requirements explicit in the brief — not assumed. Every campaign brief sent to creators should include: the required disclosure language (e.g., "This post must include #ad or 'Paid partnership' in the first line of the caption"), the platform-specific requirements (e.g., "Please activate TikTok's Branded Content toggle"), and a statement that compliance with disclosure requirements is a condition of the partnership agreement.
Contracts and creator agreements should also specify disclosure requirements explicitly. For agencies managing campaigns on behalf of brands, the contract should make clear that the agency is responsible for ensuring creator compliance and for monitoring published content. A well-drafted creator agreement will include a representation from the creator that they will comply with all applicable advertising disclosure regulations and platform policies, and that failure to disclose properly is grounds for withholding payment.
Content Review and Monitoring
Requiring disclosure in the brief is necessary but not sufficient — brands and agencies should also check that published content is compliant before approving payment. A basic review process should check: that the "#ad" or equivalent label appears before any "see more" break in the caption, that the platform branded content label is activated, that for video content a verbal or on-screen disclosure appears early in the video, and that the overall impression of the post is clearly commercial rather than organic.
For large-scale campaigns with many creators, a systematic content audit is worth the operational investment. Non-compliant posts should be flagged to the creator immediately for correction — the ASA and FTC both consider post-publication correction as a mitigating factor in enforcement actions, but the original non-compliant post is still a liability while it is live.
Gifted vs Paid: Does the Distinction Matter for Disclosure?
Yes — but less than many brands assume. The FTC and ASA both treat gifted content as requiring disclosure in most circumstances. The key regulatory test is whether there is a material connection between the brand and the creator — and receiving free product is generally considered a material connection, particularly if the brand had any input into, approval of, or influence over the content. Brands that seed products to creators without any formal arrangement and without any expectation of content ("pure gifting") are in a different position from brands that send product with a brief, but the line is blurry in practice.
The safest approach for brands is to treat all creator content where product was provided free as requiring disclosure — and to communicate this expectation to creators clearly in the seeding outreach. Most creators who receive gifted products are already aware of their disclosure obligations and will default to "#gifted" labelling. In the UK, brands should remind creators that "#gifted" alone is not sufficient and that "#ad" is required even for gifted content where the creator had genuine editorial control.
The safest operational rule: any creator content produced about your brand where your brand had any involvement — payment, product, brief, or approval — should be treated as requiring clear "Ad" disclosure.
International Campaigns: Multi-Market Compliance
Brands running campaigns across multiple markets face the challenge of navigating different regulatory regimes with different specific requirements. The practical approach is to apply the most stringent standard across all markets — if a campaign runs in both the US and UK, applying ASA disclosure standards (explicit "Ad" language) satisfies both regimes. For campaigns that extend into the EU, the EU's Unfair Commercial Practices Directive similarly requires that commercial communications be clearly identifiable as such.
Creator agreements for international campaigns should specify which jurisdiction's disclosure standards apply, and the brief should include the disclosure requirements for each market if they differ. For global creator campaigns, a single universal disclosure standard — prominent "Ad" disclosure in all posts — is both the simplest and most defensible compliance approach.
