# Designing an affiliate programme

## What affiliate marketing is

In an **affiliate programme**, partners (publishers, bloggers, review sites, creators, cashback and coupon sites, comparison sites) promote your products and earn a commission on sales they refer, tracked through links or codes. You pay mainly for results.

## Types of affiliates

| Type | Value | Watch out for |
|---|---|---|
| Content and review sites | Reach shoppers researching purchases | Quality and accuracy of content |
| Creators and influencers | Trust and demonstration | Disclosure; audience fit |
| Comparison sites | High-intent shoppers | Price competition |
| Cashback and loyalty sites | Conversion and repeat purchase | May reward customers who would buy anyway |
| Coupon / voucher sites | Conversion at checkout | Often intercept existing customers; low incrementality |
| Sub-networks | Scale | Less control over where you appear |

## Setting up a programme

1. **Platform**: join an affiliate network (which provides tracking, payments and a publisher marketplace) or use in-house affiliate software integrated with your store.
2. **Commission structure**: percentage of sale or fixed amount; consider different rates by product margin or affiliate type; bonuses for new customers.
3. **Cookie / attribution window**: the period after a click during which a sale is credited (for example, 7 to 30 days). Longer windows attract partners but increase cost.
4. **Terms**: allowed promotion methods, brand bidding rules (can affiliates bid on your brand name in search ads?), use of trademarks, coupon use, disclosure requirements, prohibited practices.
5. **Creative assets**: product images, banners, brand guidelines, product feeds.
6. **Payment terms**: validation period (to account for returns and cancellations) before paying commission.

## Commission maths

```
Average order value: 120
Contribution margin before marketing: 45% -> 54 per order
Affiliate commission: 10% -> 12 per order
Network fee (if any): e.g. a percentage of commission

Contribution after affiliate cost: 54 - 12 - fees
```

Set commission levels so the programme remains profitable, and consider higher commissions for **new customers** (who are more valuable than existing customers who would buy anyway).

## Fraud and low-quality traffic

Watch for:

- **Cookie stuffing**: dropping affiliate cookies without genuine clicks.
- **Brand bidding** against your terms.
- **Fake orders** or self-referrals to earn commission.
- **Coupon code hijacking**: codes intended for one partner appearing on coupon sites.
- **Toolbar or extension interception** at checkout.

Controls: clear terms, monitoring conversion paths, validation periods, reversing commissions for returns and fraud, and removing violating affiliates.

## Compliance

Affiliates must disclose their commercial relationship clearly (for example, "I earn a commission if you buy through this link"), in line with advertising rules such as the FTC's guidance in the US and ASA/CAP rules in the UK, and local requirements elsewhere. Your terms should require it, and you should monitor compliance — brands can be held responsible for misleading promotion by partners.

## Worked example: a Gulf electronics retailer

The retailer launches an affiliate programme:

- Content partners (tech review sites and YouTube creators): 6% commission, 30-day window, higher rate for new customers.
- Cashback sites: 3% commission, only for new customers.
- Coupon sites: limited to exclusive codes with lower commission; brand bidding prohibited.
- Commission validated after the return window.

After three months, analysis shows content partners drive the highest share of new customers, while coupon sites mostly convert existing customers already in checkout. The retailer shifts budget toward content partners.

## Networks, platforms and tracking in 2026

- **Networks and platforms**: global options include Awin, Impact.com, CJ and Rakuten Advertising; in the Gulf, regional networks such as ArabClicks and global networks with MENA publishers are common; marketplaces run their own programmes (e.g. Amazon Associates, and affiliate programmes on noon and Daraz — check current availability). Shopify and WooCommerce also have affiliate apps for smaller in-house programmes.
- **Tracking**: browser cookies are increasingly limited, so prefer **server-to-server (postback/API) tracking** or platform integrations, with codes as a backup. Agree the attribution window and what happens with returns and cancellations *before* launch.
- **Coupon codes**: unique codes per partner help attribution offline and in chat-based sales (WhatsApp), but leak to coupon sites — see the measurement lesson.

## Hands-on: set commissions from contribution, not revenue

```python
def max_commission_rate(aov: float, gross_margin: float, variable_costs: float,
                        target_contribution_share: float = 0.5) -> float:
    """Highest commission (% of order value) that still leaves the target share of
    per-order contribution for the business."""
    contribution = aov * gross_margin - variable_costs
    if contribution <= 0:
        raise ValueError("Orders are not profitable before commission")
    return contribution * (1 - target_contribution_share) / aov

for category, aov, margin, costs in [("fashion", 220, 0.60, 35), ("electronics", 900, 0.18, 40)]:
    rate = max_commission_rate(aov, margin, costs)
    print(f"{category:12s} max commission ~{rate:.1%} of order value")
```

The same headline commission rate can be generous in one category and ruinous in another. Consider higher rates for **new customers** and lower (or zero) rates for existing customers or discount-code-only sites.

## Compliance essentials

- Affiliates must **disclose** the commercial relationship clearly (FTC Endorsement Guides in the US; ASA/CMA guidance in the UK; local rules in the Gulf and Pakistan). Put disclosure requirements in your terms and monitor them.
- Ban **brand bidding** (bidding on your brand name in search ads) and **trademark misuse** unless explicitly allowed.
- Prohibit **cookie stuffing**, incentivised clicks, fake reviews and misleading claims; reserve the right to reverse commissions for fraud and returns.

## Common mistakes

- Paying the same commission to all affiliate types regardless of incrementality.
- No validation period for returns.
- Allowing unrestricted brand bidding.
- No monitoring of disclosure.
- Recruiting affiliates without audience fit.

## Recruiting good affiliates

Start with partners who already reach your customers: bloggers and reviewers in your category, creators who have mentioned your products organically, loyal customers with audiences, and complementary brands. Approach them with a clear value proposition — commission, exclusive products or early access, assets, and responsive support — and start with a small group you can manage well before opening the programme widely.

## Lecture transcript

### Designing an affiliate programme

Imagine hundreds of websites, creators and communities recommending your products, and you only pay when they make a sale. That's the promise of affiliate marketing. The risk is that you end up paying commission for sales you would have made anyway, or for traffic that breaks your brand's rules. In this lecture you'll learn the types of affiliates, how to set up a programme, how to set commissions from contribution margin, how tracking works now that cookies are limited, how to prevent fraud, and the compliance essentials. Then you'll watch me calculate a sustainable commission rate.

### Why affiliates

Why affiliates? Because they extend your reach into places you can't easily buy: trusted review sites, niche blogs, comparison sites, creators and communities. Payment is usually based on results, which reduces risk. But affiliate programmes need design. Different partners add very different value. A detailed product review that introduces your brand to new customers is worth more than a coupon site that appears at checkout for someone who was buying anyway.

### Types of affiliates

Types of affiliates. Content publishers and review sites. Comparison and deal sites. Coupon and cashback sites. Creators and influencers on commission. Loyalty and rewards platforms. Communities and newsletters. And B2B partners. Each sits at a different point in the customer journey. Content and creators often introduce new customers. Coupon and cashback sites often appear at the end, when the decision is almost made. Your commission structure should reflect that difference.

### Setting up

Setting up a programme. Choose a network or platform: global options include Awin, Impact dot com, CJ and Rakuten Advertising; in the Gulf, regional networks like ArabClicks are common; and marketplaces run their own programmes. Smaller brands can run in-house programmes with affiliate apps on Shopify or WooCommerce. Then write clear terms: commission rates, attribution window, what happens with returns and cancellations, disclosure requirements, and banned practices like bidding on your brand name. Create a partner kit with product information, approved claims and creative.

### Commission maths

Now the maths. Set commissions from contribution, not revenue. Start with your order value, gross margin and variable costs like shipping, payment fees and returns. That gives contribution per order before commission. Decide what share of that contribution you're willing to give a partner for a new customer, say half. The maximum commission rate follows. The same ten percent headline rate can be generous for fashion with high margins and ruinous for electronics with thin ones. And consider higher rates for new customers than for returning ones.

### Tracking in 2026

Tracking has changed. Browser cookies are increasingly limited by privacy features and consent choices, so relying only on cookies undercounts partner sales. Prefer server-to-server tracking, also called postback or API tracking, or platform integrations, with discount codes as a backup. Agree the attribution window before launch. Decide how you'll handle multiple partners touching the same sale. And reverse commissions for returns and cancellations, as stated in your terms.

### Fraud and low-quality traffic

Fraud and low-quality traffic. Watch for cookie stuffing, where a site drops tracking cookies without a real click. Bidding on your brand name in search ads to intercept customers already looking for you. Incentivised clicks. Fake orders that are later cancelled. And coupon sites publishing codes that were meant for one creator's audience. Monitor conversion patterns, click-to-order times, return rates and new-customer rates by partner, and reserve the right to reverse commissions for fraud.

### Simple example: Gulf electronics

A simple example. A Gulf electronics retailer launches an affiliate programme at a flat eight percent. Within weeks, most commissions go to coupon and cashback sites, for customers who were already at checkout. Meanwhile, a few tech review sites send new customers but earn little, because the coupon sites get last click. The retailer restructures: a higher rate for new customers from content partners, a lower rate for coupon sites, and a ban on brand bidding. Commission spend becomes more closely tied to real growth.

### Realistic example (illustrative)

Now a realistic scenario with illustrative numbers. A UK fashion brand has an average order of two hundred and twenty pounds, sixty percent gross margin, and thirty-five pounds of variable costs per order. That's about ninety-seven pounds contribution per order before commission. They're willing to give half to a partner for a new customer. So the maximum commission is about twenty-two percent of order value. An electronics retailer with a nine hundred pound order, eighteen percent margin and forty pounds of costs has about a hundred and twenty-two pounds of contribution; half of that is under seven percent of order value. Same logic, very different rates.

### Watch me do it: max commission

Watch me calculate it. I write a small Python function with order value, gross margin, variable costs, and the share of contribution I want to keep. It computes contribution per order, raises an error if orders aren't profitable before commission, and returns the maximum commission rate as a percentage of order value. I run it for fashion and electronics. Fashion comes out around twenty-two percent. Electronics comes out under seven. Now I can set a new-customer rate, a lower returning-customer rate, and a separate rate for coupon sites, all grounded in real economics instead of copying a competitor's headline number.

### Compliance

Compliance essentials. Affiliates must clearly disclose the commercial relationship: in the US under the FTC's Endorsement Guides, in the UK under ASA and CMA guidance, and under local rules in the Gulf and Pakistan. Put disclosure requirements in your terms and monitor them. Ban brand bidding and trademark misuse unless you explicitly allow them. Prohibit fake reviews, misleading claims and incentivised clicks. And give partners an approved claims list, especially for health, beauty and finance products.

### Recruiting affiliates

Recruiting good affiliates. Look for partners whose audience matches your customers: niche blogs, review sites, newsletters, YouTube channels and communities. Check their content quality and whether they already mention competitors. Offer a strong partner kit, fast approvals, reliable payments and a real contact person. Start with a small group of high-fit partners rather than approving everyone. And review performance quarterly, moving the best partners to better terms.

### Common mistakes

Common mistakes. Flat commissions for every partner type. Setting rates from revenue, not contribution. Relying only on cookies. Paying commission on returned orders. Allowing brand bidding. No disclosure monitoring. And approving every applicant, then never checking who's actually driving value.

### Affiliates in the AI era

One more modern consideration: AI answers and affiliate content. As shoppers ask AI assistants for recommendations, some affiliate sites are shifting from simple review pages to deeper testing, comparison tables and original data, because thin content gets less visibility. For your programme, that's a reason to value partners who genuinely test products and publish detailed, disclosed reviews, and to give them the facts, samples and access they need to do it well. It's also a reason to watch for partners using AI to mass-produce thin pages or fake reviews, which breaks your terms and, in the US and UK, the law.

### Recap

Recap. Affiliate programmes extend your reach and pay for results, but only if you design them well. Match partner types to the customer journey, set commissions from contribution margin with higher rates for new customers, use server-side tracking, reverse commissions for returns and fraud, ban brand bidding, and require clear disclosure. Try this now: run the commission function from the lesson text for your top categories, and draft a tiered rate card for content, creator and coupon partners.

## Key takeaways

- Affiliate programmes pay partners commission on referred sales.
- Design commission, attribution windows, validation periods and terms deliberately.
- Coupon and cashback affiliates may reward sales that would happen anyway.
- Require and monitor disclosure; watch for fraud such as cookie stuffing and brand bidding.
