The Legal Aspects of Influencer Contracts and Social Media Advertising

Entrance

Social media has become more than just a promotional platform for brands; it's a direct sales channel, reputation management, audience building, and consumer behavior modeling medium. Content creators on platforms like Instagram, TikTok, YouTube, X, Twitch, Facebook, LinkedIn, and others can significantly impact their followers, directly influencing brand sales through product recommendations, experience sharing, unboxing videos, discount codes, live streams, stories, reels, shorts, or sponsored videos.

Therefore, influencer contracts and social media advertisingare extremely important areas in terms of contemporary information technology law and advertising law. The collaboration between an influencer and a brand is not simply a commercial relationship of "make a post, get paid." This relationship involves consumer law, advertising legislation, unfair commercial practices, the prohibition of covert advertising, intellectual property, trademark rights, personal data protection, tax law, contract law, and liability for damages.

One of the most important texts regarding advertising by social media influencers in Turkey the Guide on Commercial Advertising and Unfair Commercial Practices by Social Media Influencers, whichThe Ministry of Trade has stated that this guide was prepared to serve as a basis for investigations into commercial advertising and unfair commercial practices by social media influencers.

Who is an influencer?

In Turkish legal practice, the term "influencer" is most often social media influencers . According to the guidelines published by the Ministry of Trade, individuals who engage in marketing communication through their social media accounts to promote the sale or rental of goods or services belonging to themselves or an advertiser, or to inform or persuade a target audience, are defined as social media influencers.

This definition is broad. A person doesn't necessarily need to have millions of followers. Micro-influencers, nano-influencers, content creators, YouTubers, TikTokers, Instagram page owners, publishers, bloggers, podcast hosts, or anyone with a niche following can all be considered social media influencers within the scope of advertising relationships.

The important thing is that a person uses their social media account to conduct marketing communication regarding a product or service. Product recommendations, sponsored videos, discount codes, affiliate links, product placement, brand tagging, product promotion in stories, service recommendations in live broadcasts, unboxing videos, or experience sharing can all be considered commercial advertising.

What is influencer advertising?

Influencer advertising is the promotion of a brand, product, or service through a social media influencer. This promotion can be a direct "buy this product" message, but sometimes it's done more subtly. For example, an influencer might present a product as a natural part of their daily life, say "I use this and love it," tag the brand, share a discount code, or tell their followers "I've left the link in the description.".

The determining factor here is whether there is a commercial relationship between the post and the brand. If the influencer receives money, free products, free services, discounts, commissions, travel, accommodation, invitations, sponsorships, affiliate earnings, or similar benefits from the advertiser, the advertising nature of the post must be clearly stated. The Ministry of Trade's announcement also clarifies that in posts where financial gain or benefits such as free/discounted goods or services are obtained from the advertiser, this must be indicated in a manner appropriate to the platform.

Therefore, the defense of "I received the product as a gift but didn't pay for it" is not always sufficient. Advertising relationships are not established solely through cash payments. Free products, discounted services, invitations, travel, commissions, or ongoing collaborations with a brand can also create a commercial relationship that consumers need to be aware of.

Ban on Covert Advertising

One of the most important legal concepts in social media advertising is the prohibition of covert advertising. The Regulation on Commercial Advertising and Unfair Commercial Practices defines covert advertising as the inclusion of names, brands, logos, trade names, or business names related to goods or services in written materials, news, publications, and programs for the purpose of advertising and presentation in a promotional manner, without explicitly stating that it is an advertisement. The same regulation stipulates that covert advertising in any form, whether audio, written, or visual, is prohibited across all communication channels.

The prohibition of covert advertising is particularly important in the context of influencer advertising. This is because followers often perceive an influencer's posts as personal experience, sincere advice, or independent opinion. If this post is actually the result of a commercial collaboration with an advertiser, failing to explicitly state this can mislead consumers.

For example, an influencer sharing a cosmetic product from a paid brand, saying "this is the best product I've used lately," without mentioning that it's an advertisement, creates a risk of covert advertising. Promoting a restaurant as "my own discovery" in exchange for a free meal invitation, describing a hotel as "my weekend getaway" in exchange for a free stay, or recommending an investment app without stating that it's sponsored can all create legal problems.

How should the #Advertising and #Collaboration hashtags be used?

In social media advertising, the advertising label must be clear, understandable, easily visible, and noticeable to the consumer at first glance. The Ministry of Trade has stated that in influencer posts, the label indicating that it is an advertisement must be distinguishable from the colors and background used in the post, in an easily readable size, and presented in a way that consumers can notice at first glance.

Therefore, the advertising tag should not be placed at the very bottom of the post, among dozens of other tags, inside the "more" section, or in a way that is not visible. Users should understand that it is a commercial advertisement when they see the post. Visibility of the advertising label is even more important in rapidly consumed content such as Instagram stories, TikTok videos, YouTube shorts, reels, or live streams.

The guidelines state that on platforms like Instagram, Facebook, and Twitter, the advertiser's name, brand, or trade name, along with at least one of the relevant hashtags, must be included within, below, or in the description of the photo or message. For short-lived content like Snapchat and Instagram Stories, the advertiser's name, brand, or trade name, along with phrases such as "#Advertisement," "#Advertisement/Promotion," or "Collaboration with @[Advertiser]" must be included for the duration of the post.

Notifications for Video, Live Stream, and Podcast Ads

YouTube, TikTok, Twitch, Instagram live streams, and podcast advertisements differ from written content. On these platforms, consumers must be able to understand the advertising context while watching or listening to the content. The Ministry of Trade's announcement clarifies that video sharing platforms like YouTube and Instagram TV, as well as live streams, must clearly state at the beginning of the advertisement that the content is an advertisement and include the advertiser's name, either in writing or verbally, without forcing consumers to click on a "read more" button.

Therefore, simply writing "collaboration" at the bottom of the video description may not be sufficient. If a product is being promoted within the video, the viewer should understand that it is sponsored content from the very beginning or when the advertisement starts. If a product is being promoted during a live stream, the explanation should be kept visible or verbally clarified at regular intervals so that users who join the stream later can also understand the advertising relationship.

The same principle applies to podcast advertisements. The listener should be able to understand whether the advice they hear is editorial content or an advertisement. A sponsored episode should begin with a clear statement such as, "This episode was produced in collaboration with the brand...".

Legal Responsibilities of Influencers

An influencer is not only obligated to produce content under their agreement with an advertiser; they are also required to advertise in accordance with regulations. Posts that are not clearly advertising, misleading, exaggerated, unproven, or that misdirect consumers may result in administrative and legal liability for the influencer.

According to the Ministry of Trade's guidelines, a social media influencer cannot promote a product or service as if they have experienced it when they have not; make unlawful health claims; or make claims based on scientific research/test results that are not supported by objective, measurable, and numerical data, or that cannot be proven. Furthermore, they cannot present a gifted product or service as if they purchased it themselves, and cannot create the impression of being solely an independent consumer while the advertising relationship continues.

Influencers should also pay attention to the use of filters and effects. Especially in advertisements for cosmetics, aesthetics, weight loss, skincare, hair care, or clothing, the use of filters can misrepresent the product's true effect. The Ministry of Trade's announcement states that if influencers use effects or filters in commercial advertisements for any product, they must clearly indicate that the image has been filtered.

Advertiser's Legal Responsibility

The biggest misconception for brands is thinking that the violation only concerns the influencer. However, the advertiser is also responsible. The Ministry of Trade's announcement states that advertisers are responsible for informing social media influencers about the guidelines and relevant legal provisions, striving to ensure compliance, and taking precautions against violations. Furthermore, it is clarified that the advertiser, advertising agency, and media organization are each individually responsible for compliance with social media influencer regulations.

Therefore, the brand should include clauses in the influencer contract such as "the term 'advertisement' will be used," "posts will comply with the Advertising Board's guidelines," "posts containing health claims will not be made," "unverified claims will not be used," and "no promises of misleading results will be made to the consumer." However, simply including clauses in the contract is not enough. The brand must review the posts before publication and intervene if there are any violations.

Advertising agencies should also be equally cautious. When creating influencer lists, agencies should consider not only follower count but also legal compliance capacity. Stricter oversight is needed, especially in sectors involving health, finance, cryptocurrency, investment, cosmetics, children's products, food supplements, and claims of rapid weight loss.

What is an influencer contract?

An influencer contract is an agreement between an advertising brand and a social media influencer that regulates the advertising, promotion, content creation, sponsorship, or collaboration relationship. This contract must be in writing. In practice, many collaborations are conducted solely via WhatsApp messages, email, or DMs. However, when disputes arise, serious problems can occur regarding payment, content delivery, posting dates, advertising tags, usage rights, revisions, cancellation, exclusivity, and liability.

A well-prepared influencer contract not only specifies the parties' fees and the number of shares, but also regulates the legality of the content, the use of advertising labels, copyright transfer, the brand's right to reuse the content, GDPR obligations, privacy clauses, penalty clauses, tax and billing procedures, performance reporting, and dispute resolution.

Therefore, an influencer contract is not like a classic service contract; it must be drafted in accordance with advertising law, consumer law, intellectual property, and digital media practice.

Essential Clauses That Should Be Included in an Influencer Contract

The influencer contract should first clearly specify the parties involved. Is the influencer an individual, a company, or acting through an agency? Is the brand contracting directly, or is it working through an advertising agency? This is important for payment, tax, liability, and reporting processes.

The scope of the campaign must be clearly stated in the contract. This should specify the number of posts, stories, reels, TikTok videos, YouTube integrations, and live streams; the dates of posts; the duration of the content; and the link, tag, hashtag, discount code, and campaign message. General statements like "will make one post" may lead to future disputes.

Advertising tags and a legal compliance clause are mandatory. It must be clearly stipulated that the influencer will use "#advertisement," "#collaboration," "advertisement/promotion," "sponsored content," or another appropriate description for the platform in their post. It should also be stated that the advertising label must be visible, understandable, and immediately noticeable to the consumer.

The contract should also regulate the content approval and revision process. Will the brand approve the content before publication? How many revisions will be allowed? Is the influencer obligated to comply with the brand's legal warnings? What will happen if corrections or removals are requested after publication? These questions must be answered in the contract.

Fees, Invoices, Taxes, and Payment Terms

The influencer contract should clearly define the fee. Is it a fixed fee, a product/service exchange, a commission per sale, pay-per-click, an affiliate revenue model, or a hybrid model? The timing and terms of payment should also be clear. For example, will payment be made before, after, or after report submission?

The invoicing and tax aspects should also be addressed. If the influencer works through a company, they can issue invoices. The tax situation for an influencer working as an individual may be different. Special tax regulations may apply to social media content creation earnings; however, the same outcome does not apply to every influencer. Therefore, the tax nature of the payment, withholding tax, invoice, receipt, or other documentation requirements should be determined in the contract in consultation with accounting consultants.

Value should also be defined in product-based collaborations. Sending a gift product does not mean there is no advertising relationship. The product price, delivery date, whether it can be returned, whether the product will be shared with an advertising label, and potential liability for defective products should be clearly regulated.

Copyright and Right to Use the Content

Photographs, videos, text, audio recordings, music arrangements, reels, TikTok videos, or YouTube content produced by influencers may be subject to intellectual property rights. Therefore, if a brand wishes to use the influencer's content on its own social media account, website, advertising campaign, outdoor advertising, or paid digital advertising, the usage rights must be clearly regulated in the contract.

The contract should answer the following questions: Can the brand share the content on its own account? Can it boost the content as advertising? Can it be used in Meta Ads, TikTok Ads, YouTube Ads, or Google Ads campaigns? What is the usage period? Is usage limited to Turkey or global? Can the influencer's name and image be used in the content? Can the content be edited or modified? Can it be transferred to third parties?

Without these clauses, a brand may only have the right to use the content for sharing on the influencer's account. Subsequent use of the content in commercials, banners, websites, or other campaigns could lead to copyright and personal rights issues.

Trademark, Logo and Third Party Rights

Influencer content may include brand names, logos, packaging, music, background images, the faces of third parties, or products from other brands. This poses risks in terms of intellectual and industrial property rights. For example, using unlicensed music in a TikTok video, the negative appearance of another brand's logo in a YouTube video, or the unauthorized inclusion of a third party's image in an Instagram post can create legal liability.

The contract should stipulate that the influencer will not infringe on third-party rights, will use royalty-free or licensed material, will comply with brand guidelines, and will obtain the necessary permissions. The brand should also inform the influencer about prohibited expressions, images, logo usage standards, competitor brand visibility, and campaign language.

KVKK and the Protection of Personal Data

Influencer campaigns may involve the processing of personal data. For example, in giveaway campaigns, followers may be asked to provide their name, surname, phone number, email address, physical address, or social media username. The use of discount codes, affiliate links, cookies, targeted advertising, campaign reports, and user interactions can also constitute personal data.

Therefore, within the scope of the campaign, it is necessary to determine who is the data controller, who is the data processor, what data is collected and for what purpose, with whom the data is shared, and for how long it is stored. Compliance with the Personal Data Protection Law (KVKK) is particularly important in campaigns involving raffles, contests, registration forms, lead generation, health/beauty analyses, test results, personalized product recommendations, or campaigns targeting children.

In campaigns where influencers collect data from their followers, the privacy policy, explicit consent, permission for commercial electronic communication, and data security measures should also be evaluated. The data may need to be deleted at the end of the campaign or retained only for legal retention purposes.

Health, Food Supplement, Aesthetics and Finance Advertisements

One of the riskiest areas for influencer advertising is sectors such as health, food supplements, aesthetics, weight loss, skincare, pharmaceuticals, clinical services, finance, cryptocurrency, investment, and betting. The Ministry of Trade's announcement states that influencers cannot make health claims that violate regulations, share claims based on unsubstantiated scientific research and test results, or direct users to goods or services offered by doctors, dentists, veterinarians, pharmacists, and other healthcare institutions.

Therefore, claims such as "I lost 8 kilos in 10 days with this product," "this cream completely eliminates wrinkles," "this investment guarantees profit," "this clinic guarantees the best results in hair transplantation," and "this supplement definitely strengthens immunity" carry serious risks. Advertisers must verify whether the claims presented by the influencer as personal experience comply with regulations.

Especially in the health and finance sectors, unsubstantiated promises can be considered misleading advertising and unfair commercial practices. Such campaigns should not be shared without a legal approval process.

Influencer advertising targeting children

Advertising targeting children is also a sensitive area. In campaigns involving toys, games, food, digital applications, children's clothing, educational platforms, or influencer campaigns producing family-child content, the child's decision-making capacity, parental consent, advertising distinctiveness, and consumer protection principles are of particular importance.

Because children are easily influenced, advertising language should not be exaggerated, oppressive, or misleading. Phrases such as "Those who don't buy this will fall behind," "Your friends are using this," or "Tell your mother to buy it immediately" can create problems under consumer law. If images of children are used in the campaign, aspects such as custody, consent, GDPR, and personal rights should be evaluated separately.

Administrative Fines in Case of Violation

The Advertising Board may impose administrative sanctions if covert advertising, misleading advertising, or unfair commercial practices are detected in social media advertisements. The Ministry of Trade's announcement regarding administrative fines for 2026 states that administrative fines under Law No. 6502 have been increased by 25.49%, the revaluation rate, effective January 1, 2026.

The Ministry of Trade has announced that the Advertising Board may impose administrative fines ranging from 99,339 TL to 39,916,524 TL in 2026 for deceptive and misleading advertisements and unfair commercial practices, taking into account criteria such as the unfair nature of the violation, the benefit obtained, the damage caused, fault, and economic situation

These figures demonstrate that influencer advertising should no longer be viewed as a "small social media collaboration." Brands, agencies, and influencers, particularly those with high follower counts, large campaigns, health/financial claims, misleading product promotions, and systematic covert advertising practices, may face significant administrative penalties.

Penalty Clauses and Liability in Influencer Contracts

The influencer contract should clearly define how liability will be shared in case of illegal content. For example, a brand may suffer damage if the influencer does not use the advertising hashtag, shares unapproved content, makes a competitor's brand visible, discloses confidential information, or violates the health claim ban.

Therefore, the contract may include clauses such as penalty clauses, compensation for damages, immediate removal of content, sharing of corrections, recourse against administrative fines, cancellation of the campaign, and payment deductions. However, these clauses must be proportionate, clear, and enforceable. Excessively harsh, vague, or one-sided clauses may lead to future validity disputes.

Similarly, influencers must also protect themselves. The contract should include protective clauses against risks such as the content provided by the brand being illegal, the product being defective, consumer complaints being placed on the influencer, the brand failing to pay, or the content being used without permission for an extended period.

Common Mistakes in Practice

The most common mistake is using the advertising tag in an invisible way. Placing the "#ad" or "#collaboration" tag at the very end of the description, among dozens of other tags, or under the "more" section, may not be immediately noticeable to the consumer.

The second mistake is not considering free gifts as advertising. However, free products, discounted services, travel, accommodation, or affiliate commissions may also require disclosure of an advertising relationship.

The third mistake is for an influencer to recommend a product without having experienced it. The guidelines prohibit sharing content that creates the impression of having experienced a product or service that one has not actually experienced.

The fourth fallacy is making unproven claims about health, beauty, weight loss, or performance. Phrases like "guaranteed results," "guaranteed effect," and "clinically proven" pose serious advertising law risks if they lack basis.

The fifth mistake is not making a written contract. Agreements made via DM or WhatsApp leave the parties facing difficulties proving their terms in case of disputes.

Conclusion

Influencer contracts and the legal aspects of social media advertising are an indispensable area of ​​compliance for brands, agencies, and content creators today. Influencer advertising has a powerful impact on consumers; therefore, it is essential that the advertising relationship is clearly stated, that covert advertising is avoided, that consumers are not misled, and that the sharing complies with the law.

The Ministry of Trade's guidelines for social media influencers require influencer advertisements to be clearly and understandably worded, to be identifiable as advertisements, and to indicate the benefit received from the advertiser in a manner appropriate to the platform. The Regulation on Commercial Advertising and Unfair Commercial Practices also prohibits covert advertising across all communication channels.

Therefore, influencer contracts should clearly regulate advertising tags, content approval, posting schedule, fees, invoicing, copyright, brand usage, GDPR, privacy, exclusivity, competitor branding restrictions, penalty clauses, content removal, and liability for administrative penalties. Campaigns conducted without a written contract pose significant risks for both the brand and the influencer.

Legal oversight is particularly crucial in sectors such as health, aesthetics, food supplements, finance, cryptocurrency, children's products, and campaigns with a large following. Unsubstantiated promises, misleading results through filters, concealing advertising information, recommending untried products, or presenting free products as purchased can lead to administrative fines and the risk of compensation claims.

In conclusion, influencer marketing is an area where creative content and legal compliance must go hand in hand. A well-prepared influencer contract, clear advertising statement, legally compliant campaign language, and regular legal checks protect the brand, agency, influencer, and consumer. In social media advertising, credibility is built not only on follower count but also on transparency and legal compliance.
