Last updated: September 2026. Affiliate marketing pays you a commission when someone you referred buys or signs up. It is genuinely one of the few online income routes that works from South Africa, and it is also widely misrepresented. The commission is the easy part. What actually determines whether you earn anything is having an audience that trusts you, which takes months to build and is destroyed quickly by promoting things you would not use.
There are two sides to this, and both are worth understanding: earning as an affiliate, and running a programme as a business that wants affiliates selling for it.
How the money actually works
Programmes pay on different events, and the difference matters more than the headline percentage.
Cost per acquisition pays when a sale completes. Commission is higher and conversion is lower.
Cost per lead pays when someone completes a form or qualifies as a lead. It pays less per action but converts far more often, which is why lead-based programmes in finance and insurance often earn more in practice than higher-percentage retail programmes.
Recurring commission pays for as long as the customer stays, and is common in software. One referral can pay for years, which makes it worth more than a larger once-off payment.
Read the cookie window and the payment terms before promoting anything. A short attribution window means you lose the commission if the buyer takes a week to decide, and long payment terms mean money you earned in January arrives in April.
Disclosure is a legal obligation, not a courtesy
If you earn from a recommendation, you must say so. Disclosure requirements for paid endorsements and commercial relationships are set out by the Advertising Regulatory Board, and they apply to a small blog or social account exactly as they apply to a large publisher.
Beyond compliance, undisclosed affiliate links on thin content is a pattern search engines actively demote, so hiding the relationship costs you traffic as well as trust. State it plainly near the link. Readers are far less bothered by it than most people expect.
Promote only what you would recommend unpaid
This sounds like advice about ethics and it is really advice about economics. An audience is the asset; the commission is just how you convert it. Recommend something poor and you trade a recurring asset for a single payment.
The affiliates who earn well tend to review a narrow category properly, say when something is not suitable, and compare options honestly including ones that pay them less. That is also the content that ranks, because it is the content people actually search for.
Where the audience comes from
You need a channel before you need a programme. Search-driven content that answers a specific buying question, a niche newsletter, a focused social account, or a community you genuinely participate in all work. Which one matters less than picking one and staying with it long enough to accumulate.
Expect months before meaningful income. Every affiliate route depends on something that compounds slowly: rankings, subscribers, followers or reputation. People who quit at three months conclude affiliate marketing does not work, when what they hit was the normal build period.
Be careful where you promote. Many programmes prohibit bidding on their brand terms in paid search or posting links in communities that did not invite them, and breaching the terms means forfeited commission.
If you are the business running the programme
Affiliate marketing is a low-risk acquisition channel because you pay for outcomes rather than impressions. To run one you need reliable tracking, clear terms covering what affiliates may and may not do, a commission rate that still leaves margin after your other costs, and a defined attribution window.
Route every affiliate link through your own tracked redirect rather than letting partners use raw network links. It keeps attribution in your control, lets you see which placements convert, and means you can change destinations without asking anyone to edit their content.
It is taxable income
Commission is income, including when it is paid from overseas in foreign currency. Earning outside a salary usually means registering as a provisional taxpayer, and records should start with the first payment.
Confirm your position with the South African Revenue Service. Payments arriving from foreign networks are visible, and an unresolved tax status will block you from funding and contracts later.
Frequently asked questions
Can you actually earn from affiliate marketing in South Africa?
Yes, including in foreign currency. What earns is an audience that trusts your recommendations, which takes months to build rather than weeks.
Which pays better, per-sale or per-lead?
It depends on conversion. Per-lead pays less per action but converts far more often, so lead-based programmes in finance and insurance frequently out-earn higher-percentage retail ones.
Do I have to disclose affiliate links?
Yes. Paid endorsements and commercial relationships carry disclosure obligations that apply to small accounts as much as large publishers, and hiding them also damages search performance.
What is a cookie window?
The period after a click during which a purchase still earns you commission. A short window means losing the sale if the buyer takes time to decide.
How long before it earns anything?
Months. Rankings, subscribers and reputation all accumulate slowly, and most people who conclude it does not work stopped during that build period.
What should a business running a programme watch?
Tracking you control, clear terms, a rate that preserves margin, and a defined attribution window. Route links through your own redirect rather than raw network links.
