Module 1: Affiliate Foundations

How Affiliate Marketing Works

Affiliate marketing is a way of earning commission by recommending other companies' products. When someone follows your link and buys, or signs up, the company pays you an agreed share. For the company, it is marketing they pay for only when it works. For you, it is a business you can start with very little money, using content you create. But it is not passive income from day one. Successful affiliates are publishers: they build an audience that trusts their recommendations. This lesson explains the mechanics so you understand exactly how you get paid.

The four parties

• The merchant (also called the advertiser or brand): the company selling the product, such as an online store, software company or hotel booking site.
• The affiliate (publisher or partner): you. You promote the product through a website, social media, email list, video channel or community.
• The customer: the person who clicks your link and takes the desired action.
• The network or platform (optional): a service that connects merchants and affiliates, provides tracking links, reports and payments. Some merchants run their own programmes without a network.

How tracking and payment work

When you join a programme, you receive a unique tracking link that contains your affiliate ID. The typical journey is:

1. A reader clicks your link on your blog post.
2. The tracking system records the click, usually by setting a cookie in the reader's browser or recording an identifier on the merchant's side.
3. The reader buys within the cookie window (or attribution window), a period set by the merchant during which your referral counts.
4. The merchant's system attributes the sale to you and records a commission, usually as "pending".
5. After a validation period, during which returns, cancellations and fraud are checked, the commission is approved.
6. You are paid once your approved earnings reach the payment threshold, on the programme's payment schedule and by its supported methods.

Each programme sets its own cookie window, validation period, threshold and payment methods. Before you join, check whether it can pay you in your country and by a method you can actually receive, which matters for affiliates in East Africa.

Commission models

Worked example: one reader, one commission

Faith writes a blog for small business owners in Kenya. She publishes "How to choose accounting software for your shop" and includes an affiliate link to a cloud accounting product. The programme (hypothetically) pays 20 percent of the first year's subscription, with a 30-day cookie window and a 60-day validation period.

A reader clicks her link on 2 March, reads the vendor's site, leaves, and returns directly on 18 March to buy a hypothetical USD 300 annual plan. Because 18 March is inside the 30-day window, the sale is credited to Faith: USD 60 pending. In May, after the validation period, it becomes approved. Faith's balance passes the programme's threshold and she is paid at the next payment date.

Had the reader bought on 10 April, after the window, or cleared their cookies, or clicked another affiliate's link later (in programmes that credit the last click), Faith would have earned nothing. Understanding attribution helps you set realistic expectations.

What affiliate income really depends on

Your earnings are roughly: traffic x click-through rate x conversion rate x average commission. If 10,000 people read your pages in a month, 5 percent click a link, 3 percent of those buy and the average commission is USD 20, you earn 10,000 x 0.05 x 0.03 x 20 = USD 300 (hypothetical figures). Each lever can be improved, and the rest of this course shows how.

Common mistakes to avoid

• Expecting quick money. Building trusted content and traffic takes months.
• Joining programmes that cannot pay you in your country.
• Ignoring programme terms, such as bans on certain advertising methods, and losing commissions.
• Promoting products you know nothing about, which damages trust and conversions.
