Affiliate marketing is the most accessible way to earn from a website: no product to build, no inventory to hold, no support tickets to answer. It is also the model most frequently ruined by the people using it, because the incentives quietly pull you away from the reader.
Done well, it is genuinely useful — you help someone choose, and the seller pays you for the introduction. Done badly, it turns a trusted site into a billboard nobody believes.
How it actually works
- You join a company’s affiliate programme and receive a unique tracking link.
- You publish content mentioning the product, using that link.
- A reader clicks. A cookie is stored in their browser identifying you as the referrer.
- If they buy within the cookie window, you earn a commission.
Two details matter far more than beginners expect.
The cookie window is how long you get credit for. Some programmes offer 24 hours; others offer 30, 60 or 90 days. A 90-day window is worth dramatically more than a 24-hour one at the same commission rate, because most people do not buy on first contact — they go away, think, and return.
The attribution model decides who gets paid when several sites referred the same buyer. Last-click is the most common: whoever referred them immediately before purchase takes the commission. That makes being the site someone consults right before buying disproportionately valuable — and it explains why comparison content outperforms everything else.
Commission rates in the real world
- Physical goods: typically one to ten percent. Large marketplaces sit at the low end. Volume is the only way this works.
- Digital products and courses: often thirty to fifty percent. No marginal cost means sellers can afford to be generous.
- Software: frequently twenty to thirty percent, and sometimes recurring — you keep earning every month the customer stays. This is the most attractive structure available to a small publisher.
- Financial and insurance products: often large flat fees, reflecting the high lifetime value of the customer.
A single recurring software commission can outperform hundreds of physical-product sales across a year. Think in terms of lifetime value, not headline percentage.
The content that actually converts
Affiliate income tracks purchase intent. Content aimed at people who are merely browsing converts poorly no matter how much traffic it attracts.
The formats that work, roughly in order:
- “Best X for Y” comparisons. The reader has decided to buy and is choosing between options. This is the highest-intent moment that exists.
- Product versus product. They have narrowed it to two. You are the tiebreaker.
- Honest reviews — especially ones that include real drawbacks. They convert better precisely because they are believable.
- Tutorials where a tool is genuinely required. The recommendation is part of the instruction rather than an interruption to it.
- “Alternatives to [popular product]”. The reader is actively dissatisfied and looking to switch — exceptionally high intent.
Notice what is absent: broad informational articles. “What is email marketing” attracts people who are not buying anything today. That content is valuable for traffic and authority, but poor for commission, and confusing the two is a common source of disappointment.
The trust problem, and why it decides everything
Here is the tension at the centre of affiliate marketing: you are paid more when people buy, but your credibility depends on being willing to tell them not to.
Every affiliate site eventually faces the moment where the higher-paying product is not the better product. What you do then determines whether you still have a business in three years.
The sites that last share some habits:
- They recommend the best product, not the best-paying one — and they say plainly when a cheaper or free option would be sufficient.
- They actually use what they recommend, and the specificity shows it.
- They name real drawbacks. “Excellent, but the mobile app is poor” builds more trust than a page of praise.
- They disclose clearly, near the recommendation, not buried in a footer.
- They turn down products they do not believe in, even lucrative ones.
Your recommendation is only valuable for as long as it is believable. Sell that too cheaply and you will have nothing left to sell.
Disclosure is a legal requirement
In most jurisdictions, including the US and UK, you must clearly disclose affiliate relationships. This is consumer protection law, not optional politeness.
Do it plainly, near the links, and before the recommendation rather than after it. Readers overwhelmingly do not mind being told. What they mind is discovering it later and feeling handled.
Getting started, practically
- Pick a niche you genuinely know. Recommendations from someone with no real experience read exactly as such.
- List the tools you already use and would recommend anyway. Start there — the writing will be honest because it is true.
- Find their affiliate programmes. Most companies have one.
- Write high-intent content first — comparisons and reviews before broad explainers.
- Then build the informational content, because that is what earns the rankings and the trust that make the commercial pages credible in the first place.
- Track what converts, and write more of that.
Mistakes that sink beginners
- Promoting everything. A site that recommends fifty products recommends nothing.
- Reviewing things you have never used. It is obvious, and it is the fastest way to lose an audience permanently.
- Chasing commission rate over product quality. Short-term revenue, long-term ruin.
- Ignoring disclosure. Legal risk and reputational risk, for no upside whatsoever.
- Building only commercial pages. With no informational content you have no authority, no rankings, and no reason for anyone to trust the recommendation.
- Expecting fast money. Affiliate income is near-zero for months and then compounds — the same curve as SEO, because it fundamentally is SEO.
The best affiliate content is what you would have written anyway if there were no commission at all, with a link added because it is genuinely the most helpful thing you can offer the reader. Everything else is a slow trade of trust for cash — and trust runs out.
Frequently asked questions about affiliate marketing
How much traffic do I need to start earning?
Far less than for display advertising, because affiliate income depends on intent rather than volume. A few hundred highly relevant visitors a month landing on a genuine comparison page can out-earn tens of thousands of casual readers. Focus on attracting the right people rather than more people.
Do I have to disclose affiliate links?
Yes. In most jurisdictions, including the US and UK, this is consumer protection law rather than a courtesy. Disclose clearly, near the recommendation, and before it rather than after. Readers overwhelmingly do not mind being told; what they resent is discovering it later.
What if I have not used the product I want to recommend?
Then do not recommend it. Reviews written by people who have never touched the product are obvious to readers and are the fastest way to lose an audience permanently. Start with the tools you genuinely use, where the writing will be honest because it is true.
Are recurring commissions really that much better?
Yes, and they are badly under-used. A software referral paying twenty percent monthly for two years is worth many times a one-off commission of the same headline rate. When choosing which products to build content around, lifetime value matters far more than the advertised percentage.
