Do You Have to Disclose Affiliate Links? (Short Answer: Yes)

You posted a link, made your first couple of sales, and then someone dropped a comment: "is this sponsored?" Suddenly you're not thinking about the commission. You're thinking about whether you just did something you're not allowed to do.

Good news first. You almost certainly did nothing wrong. Affiliate links are completely legal, and millions of creators use them every day. But there is one rule you genuinely have to follow, and it trips up beginners constantly because nobody explains it in plain language. So let me do that.

This isn't legal advice, and the specifics vary depending on where you and your audience live. But the core idea is the same in pretty much every country, so once you understand it you'll be fine almost anywhere.

The rule, in one sentence

If you earn money or get anything of value when someone buys through your link, you have to tell people that before they click.

That's it. That's the whole thing. The reason is simple: a recommendation reads differently when the person making it gets paid. Your audience deserves to know that before they decide to trust your suggestion. Regulators see an undisclosed affiliate link as a hidden ad, and hidden ads are what they go after.

Who actually enforces this

Most creators never hear a peep, and then assume the rule is optional. It isn't. The bodies that care about it include the FTC in the United States, the ASA and CMA in the United Kingdom, and the ACCC in Australia. The EU has its own consumer protection rules that land in the same place.

They rarely chase a small creator over a single missing disclosure. What they do is go after patterns, big accounts, and brands that coach their creators to stay quiet. The platforms themselves also enforce it. Instagram, TikTok, and YouTube can all limit your reach or remove content if you're running undisclosed paid promotion, and they're getting better at spotting it.

So the realistic risk for a beginner isn't a fine. It's getting your content suppressed, or losing the trust of an audience you worked hard to build. Both of those hurt your income more than a disclosure ever could.

What counts as a proper disclosure

A disclosure only works if a normal person actually notices it and understands it. That rules out a few popular shortcuts:

• Burying it. A line of text under fifteen hashtags at the very bottom of a caption does not count. It has to be somewhere people see before they act on the link.
• Being vague. "Thanks to my partners" or "sp" or a lone affiliate emoji doesn't tell anyone anything. Plain words win.
• Relying only on the platform tag. The "paid partnership" label and the YouTube "includes paid promotion" box are good, but treat them as a backup, not your whole disclosure. Say it in your own words too.

What does work is short, clear, and upfront. You don't need a paragraph of legalese. You need one honest line in language a twelve year old would understand.

Wording that works

Here are phrases you can paste straight in and adjust to your voice:

• "This post contains affiliate links. If you buy through them I earn a small commission at no extra cost to you."
• "Heads up, some of these are affiliate links, so I get a little kickback if you grab something."
• "I earn from qualifying purchases through the links below."

Notice none of these are apologetic, and none of them are buried. The "no extra cost to you" part is worth keeping because it's true for the buyer and it removes the one objection most people have.

For short formats like a TikTok or a Reel, you don't have room for a sentence in the first second of video, so put a clear line near the top of the caption and say it out loud if it fits naturally. For a link in bio, a one line note on the page the link points to does the job.

Will it cost you sales?

This is the real fear, and it's backwards. Creators worry that admitting they earn a commission will make people click away. In practice the opposite tends to happen.

Think about how you feel when a creator is upfront with you. You trust them more, not less. The disclosure signals that they're not hiding anything, which makes the actual recommendation feel more credible. The buyer also learns the link costs them nothing extra, which removes the suspicion that you only recommended the expensive option to pad your cut.

The creators who lose trust are the ones who get caught hiding it. A viewer who figures out on their own that you've been quietly earning from every link will discount everything you say next. Telling them yourself is cheaper than getting found out.

A thirty second checklist

Before you publish anything with an affiliate link, run through this:

1. Is there a clear line saying the link earns you a commission?
2. Is that line visible before someone clicks, not buried at the bottom?
3. Is it in plain words, not jargon or a vague emoji?
4. If the platform has a paid-promotion toggle, did you also switch it on?
5. Would a stranger scrolling fast actually notice it?

If you can answer yes to all five, you're done. You can stop worrying about the rule and get back to the part that actually grows your income, which is recommending things your audience genuinely wants.

Disclosure isn't a tax on honest creators. It's the thing that lets you keep being one.
