Affiliate Marketing 101 for Bloggers
Affiliate marketing can be a blogger’s best friend…or a legal headache waiting to happen. The difference? Knowing the rules before you start linking.
As a lawyer and blogger, I know how affiliate income can open doors, and how a single misstep can get you booted from a program or fined by the FTC. So, let’s talk about how to do affiliate marketing the right way: clearly, ethically, and profitably.
Whether you’re just getting started or wondering if you’ve been doing it by the book, this guide covers the essential legal and practical tips every blogger needs to know.

What Is Affiliate Marketing, Exactly?
Affiliate marketing is a performance-based income stream where you earn a commission for referring someone to a product or service. You promote a link, someone clicks it and makes a purchase, and voilà(!) you get paid.
Sounds easy, right? Technically it is, but there’s a lot more to doing it well and legally.
Here’s how it typically works:
- A company gives you a custom link (your affiliate link).
- You place that link in your blog content, email newsletter, or social post.
- If someone clicks your link and buys something, you get a cut (commission percentages vary).
How Do Bloggers Make Money With Affiliate Links?
Commissions vary wildly. Some brands offer 3%, others offer 40% (like The Blog Law Guide affiliate program, for example), and subscription services often pay per sign-up. Here are common ways bloggers use affiliate marketing:
- Product roundups (e.g., “My Favorite Tools for DIY Home Projects”)
- Tutorials and how-tos that include tools or products
- Reviews of products or software
- Evergreen blog posts with links that keep earning over time
- Resource pages with affiliate tools and links
Just make sure the products are ones you genuinely use or believe in. Your readers can tell when you’re just chasing commissions, and that’s how trust (and traffic) dies.
Do You Have to Disclose Affiliate Links?
Yes. No matter where you are in the world, if you’re using affiliate links, you almost certainly have to disclose them, and not just because it’s the ethical thing to do.
Disclosure requirements are based on where your readers are, not where you blog from. That’s a crucial point. If someone in London, Sydney, Toronto, or Paris clicks your link, you may be legally obligated to follow their country’s consumer protection laws, even if they’re different than your country’s laws.
United States
In the U.S., the Federal Trade Commission (FTC) requires clear and conspicuous disclosure of any “material connection” between a content creator and a brand. This includes affiliate links. If you earn money when someone clicks a link or makes a purchase, you must disclose that relationship before the link appears. Burying it in a footer, sidebar, or policy page won’t cut it.
Disclosures must be:
- Clear: No vague language like “may contain affiliate links.”
- Prominent: Near the top of the content and before the first affiliate link.
- In plain language: Like “This post contains affiliate links, which means I may earn a commission if you click through and make a purchase. It doesn’t cost you anything extra.”
Outside the US
Most countries with consumer protection laws have similar requirements. Here are a few common examples:
- United Kingdom: The Competition and Markets Authority (CMA) mandates upfront, unambiguous disclosure of paid promotions or affiliate relationships when targeting UK consumers.
- European Union: Under the Unfair Commercial Practices Directive, any content with commercial intent must disclose that fact clearly, especially if it might influence consumer decisions.
- Canada: The Competition Bureau expects “material connections” like affiliate links to be disclosed in a way that’s clear, prominent, and understandable to the average person.
- Australia: The Australian Competition & Consumer Commission (ACCC) requires bloggers and influencers to be transparent about paid content, including affiliate partnerships.

The universal theme? If you’re promoting something and earning money, or even just getting free products, you need to be upfront about it. Early, clearly, and in a way your readers actually see.
When in doubt, disclose. Transparency isn’t just legally safer, it also builds trust, which is the real foundation of long-term affiliate income.
What Does a Proper Disclosure Look Like?
Please Note: The examples in this guide are for informational and educational purposes only and are not legal advice. Whether a specific disclosure is appropriate or sufficient will depend on the content, platform, and context of your post.
Good disclosures are:
- Clear: Avoid vague terms like “may contain affiliate links.” Say what it is.
- Placed prominently: Ideally near the top of your post, and before the first affiliate link.
- In plain English: “This post contains affiliate links, which means I may earn a commission if you click through and make a purchase. It doesn’t cost you anything extra.”
Here are a few examples of disclosures language:
- “Heads up: This post includes affiliate links. That means I may earn a small commission (at no extra cost to you) if you buy something I recommend.”
- “This post contains affiliate links. I earn a commission if you purchase through these links.”
- “Disclosure: Some of the links below are affiliate links, meaning I may receive a commission if you click through and make a purchase.”
Do You Need a Disclaimer or Privacy Policy Too?
Yes again. If you’re collecting any kind of user data (think email signups, contact forms, analytics), or using affiliate links, you need a privacy policy that reflects that. Some affiliate programs even require it as part of their terms.
Your disclosures and disclaimers should explain:
- That you use affiliate links and may earn a commission
- That you only recommend things you genuinely like
- Any limitations on liability (especially for health, finance, or legal advice)
Best Practices for Ethical Affiliate Marketing
Want to stay in good standing with your readers and the law? Follow these golden rules:
- Be honest. Only promote products you trust.
- Disclose every time. Even in emails, podcasts, and social media captions.
- Use nofollow or sponsored tags. Google expects affiliate links to be marked appropriately.
- Understand each program’s terms. Violating them can get you kicked out (and unpaid).
- Maintain your links. Check regularly to fix broken links, update outdated products, and ensure every link goes where it should.
Affiliate Marketing Isn’t Passive (At First)
Affiliate income is often called “passive,” but there’s nothing passive about writing a strategic blog post, embedding links, optimizing for SEO, and building trust with your audience. It takes time. But the payoff is real, and scalable.
Start by choosing programs that fit your niche, write useful content that includes them naturally, and disclose everything clearly. That’s the recipe for both compliance and long-term income.
