Introduction
A website can generate consistent search traffic and still produce disappointing affiliate income if every successful referral earns only a small commission. This is one of the most common reasons affiliate sites underperform: the economics of the products being promoted simply do not leave enough money to share. Low-margin categories such as groceries, household essentials and many consumer goods often pay modest commission rates, meaning publishers must generate far more qualified visitors to achieve the same income as websites promoting higher-value or higher-margin products. Affiliate networks consistently note that commission structures are largely determined by product margins, making low-payout categories fundamentally different from software, financial services or subscription products.

Understanding this relationship is essential when estimating the earning potential of an affiliate website. Traffic matters, but the value of each successful referral matters just as much.
How low commission rates shrink each sale
Affiliate income depends on several linked factors, but commission rate has an unusually strong influence because it limits the maximum revenue available from every completed purchase.
Consider two simplified examples where both merchants convert visitors equally well:
Product categoryOrder valueCommissionEarnings per saleWeekly grocery order£802%£1.60Specialist software subscription£8030%£24.00
Even though customers spend the same amount, one completed referral produces fifteen times more revenue than the other.
The difference becomes even larger when digital products, subscriptions or business software pay recurring commissions or generous revenue shares. By contrast, merchants selling physical products with thin profit margins often have little room to increase affiliate payouts because doing so would erode their own profitability. Industry guidance from affiliate networks explicitly recommends lower commissions for lower-margin products and higher commissions where margins allow.

This is why increasing traffic alone does not always solve an affiliate site’s revenue problem. If every sale is worth only a pound or two, enormous visitor numbers may still produce modest monthly income.
Why grocery and everyday items need scale
Groceries, toiletries, cleaning products and other everyday purchases illustrate the challenge particularly well.
These products have several characteristics that reduce affiliate earnings:
- Retail profit margins are often relatively small.
- Individual basket values may be moderate.
- Commission percentages are usually conservative.
- Many shoppers compare prices aggressively before purchasing.
From the merchant’s perspective, low commissions are often a commercial necessity rather than a lack of generosity. Affiliate platforms advise advertisers to match commission rates to sustainable product margins instead of paying uniform percentages across all products. Some programmes therefore pay different rates for different product categories within the same retailer.

For affiliates, this creates an important strategic distinction. A website recommending everyday supermarket products may genuinely help readers, but each completed purchase contributes only a small amount towards overall revenue. The publisher therefore depends heavily on scale: more pages, more ranking keywords and significantly more qualified visitors.
Traffic scenarios that reveal weak payout maths
The practical effect becomes clearer when realistic traffic scenarios are compared.
Imagine a website receives 100,000 monthly visitors.
Assume:
- 3% of visitors click an affiliate link.
- 4% of those clicks become purchases.
- Average order value is £75.
That produces:
- 3,000 affiliate clicks.
- 120 completed orders.
Now compare different commission structures.
Commission rateEarnings per saleMonthly commission2%£1.50£1805%£3.75£45015%£11.25£1,35030%£22.50£2,700
Nothing changed except the commission percentage, yet total income increased fifteen-fold between the lowest and highest examples.
This illustrates why publishers often overestimate the value of raw traffic. A six-figure monthly audience sounds impressive, but if each successful referral earns only a small amount, substantial operating costs and content production may still outweigh revenue.
Why simply adding more visitors has diminishing returns
When commissions are low, publishers often assume that doubling traffic will solve the problem. In reality, scaling traffic becomes progressively harder and more expensive.
Higher traffic usually requires:
- Publishing substantially more content.
- Competing for broader search terms.
- Acquiring stronger backlinks.
- Maintaining larger websites.
- Updating more pages as products change.
If revenue per visitor remains extremely low, these additional costs may grow almost as quickly as income.
Affiliate networks frequently evaluate programmes using metrics such as earnings per click (EPC), because EPC combines conversion performance with commission size. A programme with modest conversion rates but generous commissions can produce a much higher EPC than a retailer converting well but paying very little per sale. Publishers therefore often compare EPC rather than commission percentage alone when deciding what to promote.

When low commissions can still make sense
Low-paying affiliate categories are not automatically poor choices.
They can perform well when combined with favourable characteristics such as:
- exceptionally large search demand;
- frequent repeat purchases;
- highly trusted brands that convert consistently;
- complementary higher-value recommendations elsewhere on the site;
- multiple affiliate opportunities within the same visitor journey.
For example, a recipe website may earn relatively little from recommending pantry staples, but considerably more from promoting premium kitchen appliances, specialist cookware or cooking courses alongside its core content. The everyday products bring relevant traffic, while higher-value recommendations improve average revenue per visitor.
This blended approach helps reduce dependence on extremely high visitor volumes while remaining useful to readers.
Choosing products with realistic earning potential
Before building an affiliate website around a product category, it is worth estimating revenue from the bottom up rather than assuming traffic alone will create meaningful income.
Questions that reveal weak payout economics include:
- How much commission is earned from a typical completed order?
- What is the average customer basket value?
- How many completed sales would be required to reach the desired monthly income?
- Is the required traffic realistically achievable within the chosen niche?
- Are there related products with stronger commission economics that naturally fit the same audience?
Working through these calculations early often prevents investing years in a niche where even successful rankings struggle to generate worthwhile affiliate revenue.
Ultimately, low-commission products demand far greater scale because each conversion contributes only a small amount to total earnings. For affiliate publishers, understanding this arithmetic before choosing a niche is often more valuable than estimating traffic alone, since the true earning potential depends on the value created by every successful referral rather than on visitor numbers in isolation.
