Stay Legal, Stay Trusted

The FTC's Endorsement Guides are the primary legal framework. Here's what they actually require, in plain English.

The Core Rule

If there is a "material connection" between you and a company whose product you are endorsing, you must disclose that connection clearly and conspicuously. That's it. Everything else is detail around what "material," "clearly," and "conspicuously" mean.

What Counts as "Material"

A connection is material if it might affect the weight or credibility a consumer gives to your endorsement. This includes: receiving a commission through an affiliate link, being paid to create content, receiving free products or services, having an employment or family relationship with the brand, receiving discounts not available to the general public, or any other benefit that a reasonable consumer would want to know about.

The bar is intentionally low. If you're asking "do I need to disclose this?" — the answer is almost always yes.

Where to Place Disclosures

The FTC uses the phrase "clear and conspicuous," which means the disclosure must be hard to miss. Specifically:

Language That Works vs. Language That Doesn't

The disclosure must use language your audience understands. Vague terms don't count. Here's a practical breakdown:

Clear language: "This post contains affiliate links. If you buy through these links, I earn a commission at no extra cost to you." Or simply: "Affiliate link" right next to the link. Or: "I earn a commission if you purchase through this link." These are direct, unambiguous, and easy to understand.

Unclear language: "Partner," "collab," "sp," "thanks to [Brand]" without context. These don't tell the reader there's a financial relationship. The word "partner" in particular is problematic because it could mean a business partnership, a content collaboration, or just that you like the brand. It doesn't communicate that you're earning money from the recommendation.

The FTC has specifically flagged that abbreviations like "sp" (for sponsored post) or standalone hashtags like #partner are not sufficient because many consumers don't understand what they mean.

FTC guidelines are the legal baseline, but each platform has its own additional rules. Violating platform rules won't get you an FTC fine, but it can get your content suppressed, your account flagged, or your monetization revoked. Here's what you need to know for each.

YouTube

YouTube has a built-in "paid promotion" toggle in the video editor. When enabled, it shows a small banner at the start of your video that reads "Includes paid promotion." You should use this toggle for any video that contains affiliate links or sponsored content. However, the toggle alone is not sufficient for FTC compliance. You still need to verbally disclose in the video itself, ideally within the first 30 seconds. Do not rely on the description box alone, because most viewers never read it.

Best practice: say something like "This video contains affiliate links in the description. If you use them, I earn a small commission" early in the video. Turn on the paid promotion toggle. Include a written disclosure at the top of your description box. Triple coverage.

Instagram & TikTok

Both platforms offer "Paid partnership" labels in their creator tools. Use them when available. On Instagram, add #ad at the beginning of your caption, not buried among 30 other hashtags at the end. TikTok works the same way: disclose at the start of your caption, and use the "Branded content" toggle when linking to products. For Instagram Stories, include a text overlay disclosure on every Story that contains an affiliate link, because Stories autoplay and the viewer may not read the caption.

TikTok Shop has its own built-in affiliate system with automatic disclosures, but if you are linking to external products through your bio link or a link-in-bio tool, the platform disclosures don't cover you. You need to add your own.

Pinterest

Pinterest requires that affiliate pins be clearly identified. The platform's terms of service require you not to cloak or hide affiliate links. Use the pin description to include a brief disclosure, such as "This is an affiliate link" or "I may earn a commission if you purchase." Pinterest also doesn't allow link shorteners that obscure the destination URL. Use direct affiliate links or transparent redirects only.

Blog & Website

For written content on your own site, place a disclosure statement at the top of any post that contains affiliate links. Not in the sidebar. Not only in the footer. At the top of the article, before the reader encounters the first affiliate link. You can use a styled box or banner to make it visually distinct without being intrusive. Many successful affiliate bloggers use a short sentence right after the post title or in a colored box before the intro paragraph.

If your entire website is affiliate-focused, having a dedicated disclosure page is also good practice, but it does not replace individual post disclosures.

Email Newsletters

If you include affiliate links in email campaigns, you need to disclose within the email itself. A common approach is to add a line near the top: "This email contains affiliate links." Some marketers add a small note next to each link. Either approach works as long as the disclosure appears before or alongside the links. Remember, your email also needs to comply with CAN-SPAM requirements (covered later in this playbook), so you're juggling two sets of rules in this channel.

The fear most affiliates have is that disclosures will scare people away. The reality is the opposite. Awkward, defensive, or overly apologetic disclosures hurt conversions. Confident, natural disclosures don't. The difference is in the tone and the framing.

The Confidence Frame

When you disclose like you're confessing to something, the reader picks up on that energy. Phrases like "I need to let you know..." or "Full transparency, I'm required to say..." sound like you're apologizing for recommending the product. That undermines trust. Instead, treat the disclosure as a normal part of doing business. Because it is.

Compare these two approaches:

The second version is matter-of-fact. It doesn't apologize. It adds context (no extra cost to you) and a reason (keeps the site running). The reader understands the deal, respects it, and moves on.

Smooth Integrations for Different Formats

Blog posts: Use a short styled box at the top of the article. Keep it to one or two sentences. Some bloggers make it a persistent banner across all affiliate content — set it up once in your template, and it's automatic.

YouTube videos: Mention it casually in the intro. Something like: "Links to everything I mention are in the description, and some of those are affiliate links." Quick, natural, done. You don't need to bring it up again.

Social media: Lead with #ad or "Affiliate link:" before the product mention. On Instagram, some creators add it as a text overlay on the image itself, which is actually great because it's unmissable.

Email: Add a one-liner near the top: "Heads up — some links in this email are affiliate links." Place it before the first link, and your entire email is covered.

Why Disclosures Can Increase Conversions

This sounds counterintuitive, but there's solid logic behind it. When you disclose upfront, you're establishing honesty as a baseline. The reader now believes you're being straight with them. So when you say "this is the best tool for X," that recommendation carries more weight because you've already proven you're not trying to hide anything. The disclosure acts as a credibility signal. It filters out suspicious readers and converts the ones who appreciate transparency. Those are the readers who buy and come back.

GDPR Basics (EU Audience)

If any portion of your audience is in the European Union, the General Data Protection Regulation (GDPR) applies to you. The key requirements for affiliate marketers: you need a cookie consent banner (affiliate links often use tracking cookies), you need a privacy policy that explains what data you collect and why, and you need to give users the ability to opt out of tracking. If you use analytics tools, email collection forms, or any kind of retargeting, GDPR applies. The fines for GDPR violations are substantial and enforcement has been increasing.

The simplest approach: use a reputable cookie consent plugin for your site, write a clear privacy policy, and make sure your affiliate tracking cookies are covered in your consent flow.

CAN-SPAM for Email Affiliates

If you send commercial emails (which includes emails containing affiliate links), the CAN-SPAM Act requires: a truthful "From" name and subject line, a valid physical mailing address in every email, a clear and working unsubscribe mechanism, and prompt processing of unsubscribe requests (within 10 business days). You cannot use deceptive subject lines like "Re: Your order" when there is no order. You cannot send emails to people who have unsubscribed. Most email service providers handle the technical compliance for you, but you're responsible for the content and the list management.

Tax Implications

Affiliate income is taxable income. In the United States, if you earn more than $600 from a single affiliate program in a calendar year, you'll receive a 1099 form. But even if you earn less than $600 (and don't receive a 1099), you are still legally required to report the income on your tax return.

Set up a simple tracking system from day one. A Google Sheet works fine — log each payment with the date, the program, the amount, and the payment method. Track business expenses too: hosting costs, software subscriptions, equipment. These may be deductible. Consult a tax professional once your affiliate income becomes significant, because the rules around self-employment tax, quarterly estimated payments, and business deductions can get complicated quickly.

Trademarks — What You Can and Can't Say

You can use brand names in your content when discussing their products — that's nominative fair use. You can write "Best Alternatives to Adobe Photoshop" or "My Honest Canva Review." What you cannot do: use brand logos without permission (most affiliate programs grant logo usage, but check your terms), imply an official endorsement or partnership that doesn't exist, or use trademarked terms in your domain name (e.g., "PhotoshopReviews.com" would be a problem). When in doubt, describe the product rather than using the trademarked name in contexts that could imply official affiliation.

These are the mistakes that get affiliates in trouble most often. Each one is avoidable, and each one has real consequences if you ignore it.
