Every car creator who earns from a link is making an endorsement, whether the post is a parts review, a restoration log or a walkaround of a car for sale. Federal rules decide how that endorsement has to be labelled, and the FTC affiliate disclosure requirements are more specific than most creators assume. A one-line note on the About page does not meet them. Neither does a tidy "affiliate link" tag. This guide works through the rule the way an engineer works through a spec: what the text requires, which wordings pass, where the disclosure has to sit in each format, and who carries the risk when it is missing. If you are still mapping out how car creators earn in the first place, start there and come back.
FTC Affiliate Disclosure Rules for Car Creators
What 16 CFR 255.5 requires, which wordings pass, where the disclosure goes in posts, videos and streams, and who is liable when it is missing.
What the FTC affiliate disclosure rule says
The governing text is the FTC's Endorsement Guides, 16 CFR Part 255. Section 255.5 sets the core test. If there is a connection between the person endorsing a product and the seller that might affect how much weight the audience gives the endorsement, and the audience would not reasonably expect that connection, it must be disclosed "clearly and conspicuously."
Three parts of that sentence do most of the work.
First, "connection" is broad. It covers payment, including a share of sales from a link, but also free or discounted products and family or business ties. A free, expensive tool sent to a creator is a connection on its own, with no money changing hands, when a significant minority of viewers would not know about it.
Second, the test is the audience's expectation, not yours. You may assume every viewer knows creators earn from links. The FTC asks whether a significant minority of them would be unaware. In practice, assume they are.
Third, the section's own examples include a blogger who earns a share of sales from links in reviews. That blogger should clearly and conspicuously disclose the compensation. This is the creator's situation exactly, so there is no gray zone to argue about.
The Guides were revised on June 29, 2023. The update added a definition of "clear and conspicuous," widened "endorsement" to cover tags in social media, and said a platform's built-in disclosure tool might not be adequate. The FTC is also plain about their status: the Guides do not have the force of law, but conduct inconsistent with them can lead to enforcement under Section 5 of the FTC Act, and they provide no safe harbor.
Wording that passes and wording that does not
The FTC's published answers on affiliate links are unusually concrete about phrasing. The summary below follows the agency's own guidance, as read in October 2026.
| Wording | FTC view |
|---|---|
| "I get commissions for purchases made through links in this post" | The FTC's own example of a clear disclosure |
| "Paid link" next to the link | Adequate |
| "Ad", "Advertisement", "Sponsored", "#ad" or "Ad:" at the start | Acceptable; #ad, Ad: and ad at the beginning are probably equally effective |
| "Affiliate link" on its own | Not adequate; many readers do not know what it means |
| A "Buy now" button | Not a disclosure |
| "Commissionable link" | Probably not clear |
| "sp", "spon", "collab", a bare "thanks" or "ambassador" | Avoid; too vague |
One clarification saves a lot of clutter: a link you share without earning anything from it needs no disclosure. The rule is about the connection, not the link itself. A link to a club's event page or to a free parts diagram is just a link.
The pattern behind the table is simple. Words a general reader understands pass. Industry shorthand fails, because the test is the reader's understanding and the reader is not in the industry.
Where the disclosure goes in each format
Placement is where most creators slip. The FTC's guidance is consistent across formats: put the disclosure with the endorsement. A statement on a profile or About page, behind a "more" link, in the comments, or behind a separate "Disclosure" hyperlink is easily missed and is not clear and conspicuous. One at the end of a post is easier to miss and less likely to work.
Written posts. Put the disclosure as close to the recommendation as possible, before the reader reaches the link. A short sentence at the top of a parts roundup works. A footer note is easy to scroll past. If the post has several affiliate links spread through it, a disclosure near each cluster is safer than a single line at the start.
Video. The disclosure belongs in the video itself, ideally in both audio and on screen, and not only in the description. For affiliate links, the FTC says to disclose both in the video and in the description near the links. When you are filming a walkaround of a car you will link to, plan the spoken line into the script rather than adding a caption later. YouTube's paid-promotion checkbox adds a label at the start of a video, but the platform itself tells creators they remain responsible for the law, and the FTC says not to rely solely on a platform tool.
Live streams. Repeat the disclosure periodically. Viewers join late and never see the opening.
Social posts. The disclosure has to appear in each post, not just the first in a series. A hashtag such as #ad is optional; if you use one, do not bury it in a run of other hashtags where it will not be noticed.
"Treat the disclosure like a torque spec. It is not a matter of taste, it goes in the same place every time, and if you skip it the failure shows up later at the worst moment."

Program contracts add their own requirements
The FTC sets the floor. Affiliate programs often build on it, and a creator usually signs up to several. A roundup of automotive affiliate programs compared by rate and cookie length is a good start, but read each program's operating agreement for its disclosure terms too.
Amazon Associates is the clearest example. Its Operating Agreement requires the statement "As an Amazon Associate I earn from qualifying purchases." to appear clearly and prominently on the site. That is a contract term, separate from the FTC test. Meeting one does not automatically meet the other: Amazon's sentence on a sidebar may satisfy the contract while the FTC still expects a disclosure near each recommendation.
Our partner program is written the same way. Its rules require partners to say they earn a commission when they share their link, as the FTC requires, and they also ban paid ads, including bids on the program's brand name, along with coupon, cashback and incentive sites, spam, and commissions on your own purchases. Breaking those rules can cost the commission even if the FTC never hears about it.
Who carries the risk if it goes wrong
The FTC says its enforcement actions usually target advertisers and their agencies or public relations firms, not individual creators. That is not the same as immunity. Action against an individual endorser is possible, for example where required disclosures keep going missing after warnings. The agency puts ultimate responsibility for disclosure on the influencer and the brand, not on the platform. A creator who is not an expert may also be liable for misleading claims about a product.
Enforcement orders can require refunds to consumers and future compliance. Companies that received an FTC Notice of Penalty Offenses on endorsements and then continue the conduct could face substantial civil penalties. For a solo creator, the practical risk is less about a federal case and more about a brand or network dropping you because your posts expose them.
A short checklist covers almost every case: disclose any connection, in plain words, next to the recommendation, in every post and video, regardless of what the platform adds. This is a summary of federal guidance, not legal advice. If your setup is unusual, such as a business channel with several partners or a brand deal with its own contract, confirm the details with an attorney who handles advertising law.
