How affiliate commission shapes what you are shown

Most skincare recommendations you encounter online pay somebody when you buy. What that changes about which products get covered, and what the disclosure rules actually require.

The short answer

Affiliate commission pays a publisher or creator a share of the sale when a reader buys through their link. It is legal and widespread, and it must be disclosed clearly. What it changes is selection: products that pay commission are more likely to be covered than products that do not, retailers with affiliate programmes are more likely to be linked than those without, and content is more likely to be built around purchasable conclusions than around advice not to buy. Disclosure addresses the relationship, not the selection effect.

This publication takes no affiliate commission, and says so on every page, because affiliate commission is one of the incentives it exists to explain. That position is not moral superiority. It is a design decision, taken because a publication that earns money when you buy something cannot credibly tell you when not to.

How the mechanism actually works

An affiliate link carries a tracking parameter identifying the publisher. When a reader clicks it and buys within a defined window, the sale is attributed to that publisher and a commission is paid, usually as a percentage of the sale value. The rate varies by retailer and category, and the window varies too.

Several parties sit in the chain. There is the retailer or brand running the programme, frequently an affiliate network administering it, the publisher or creator, and sometimes an agency managing the relationship. Money flows from the retailer's marketing budget, which means it comes from the price of the product, as described in the economics of a moisturiser.

What it changes, which is selection

The common defence of affiliate content is that commission does not change what a writer thinks about a product. Frequently that is true. It is also not the mechanism that matters. The effect operates on what gets covered at all, and on the shape of the content.

  • Coverage follows programmes. A product sold only through a retailer with no affiliate programme is less likely to appear in a list than an equivalent product sold somewhere that pays.
  • Formats favour purchase. Best of lists, dupes and comparison pieces convert. An article concluding that you do not need anything does not.
  • Rates influence emphasis. Where categories pay different rates, the categories that pay more receive more attention over time, without any individual decision being made.
  • Retailer choice follows commission. The link goes to the retailer that pays, which is not necessarily the cheapest.
  • Update cycles follow revenue. Pages that earn get maintained. Pages that do not, decay.

None of this requires anyone to recommend a product they dislike. It is a filter applied before the recommending starts, and it is invisible to readers because the alternatives that were never considered leave no trace.

Permitted to mean

That the publisher has a commercial relationship with a retailer or brand and is paid when readers buy through its links. Disclosure of this kind is required, and the wording is conventional.

The word small is doing no work at all: there is no threshold that makes a commission small, and rates are not disclosed.

Does not mean

It does not tell you the rate, the retailer, whether rates differ between the products listed, or whether any product in the piece pays more than the others. It does not tell you whether products without affiliate programmes were considered and dropped. It does not tell you whether the ranking correlates with the commission. It does not mean the recommendation is independent, only that the relationship has been declared.

What would have to be true

A disclosure that actually informed you would state which links are commissioned, whether rates differ across the products listed, and whether any product was included or excluded for commercial reasons. Almost no publisher does this, because the disclosure requirement is satisfied by declaring the relationship rather than by describing its effect.

The rule behind it. Advertising must be obviously identifiable as such. Under the CAP Code and consumer protection law, including the provisions of the Digital Markets, Competition and Consumers Act 2024, commercial relationships affecting content must be disclosed clearly and prominently.

What the rules actually require

The core principle is that marketing communications must be obviously identifiable as such. Where content is controlled by a brand and paid for, it is advertising and must be labelled. Where a creator has a commercial relationship affecting what they say, that relationship must be made clear before the audience engages with the content, not buried at the end.

The 2024 reforms strengthened this. Hidden advertising, fake reviews and incentivised reviews presented as independent are addressed directly by the consumer provisions of the Digital Markets, Competition and Consumers Act 2024, with enforcement powers held by the Competition and Markets Authority. The ASA continues to handle advertising disclosure under the codes, and Trading Standards enforce consumer protection law.

Three arrangements that look similar and are not
ArrangementWho controls the contentWhat must be disclosed
Affiliate linkThe publisher, who is paid only if a sale resultsThat a commercial relationship exists and links may earn commission
Paid partnership or advertorialThe brand, which has approval over the contentThat it is advertising, clearly and before engagement
Gifted productThe creator, who received the product free and was not paidThat the product was gifted, where it may affect how the content is understood

The middle row is the one most often mislabelled. Content the brand can approve is advertising, whatever it is called, and a small tag at the end of a caption is not disclosure before engagement.

Who profits

Why recommendation media converged on this model

Display advertising pays poorly and declines with ad blocking. Subscriptions are hard to sell for buying advice. Affiliate commission pays for the exact action the content is designed to produce, which makes it the most efficient available model for anybody publishing recommendations.

Once one publisher adopts it, competitors must match the revenue or lose the ability to fund the work. The entire category then reorganises around purchasable conclusions, and content that does not end in a purchase becomes economically unviable.

That is why so much skincare journalism is a list. Not because writers prefer lists, but because a list is the format the funding mechanism rewards.

  • Retailers. Buy demand at a fixed cost per sale, with no payment for coverage that does not convert
  • Affiliate networks. Take a share of every commissioned transaction across the sector
  • Publishers and creators. Fund editorial work through a model that pays reliably
  • Brands without programmes. Receive systematically less coverage, regardless of merit
  • Readers. Get abundant advice about what to buy and very little about what not to

Reviews, ratings and the incentive underneath them

Reviews on retail sites operate in the same economy. Retailers benefit from a high average rating. Brands run seeding programmes that supply free product in exchange for reviews. Review syndication means the same reviews appear across multiple retailers. Incentivised reviews are permitted only where the incentive is disclosed, and fake reviews are prohibited outright.

The practical reading discipline is to ignore the average and read the distribution. Look at the one and two star reviews, look for mentions of texture change, irritation or a formula that seems different from a previous purchase, and check whether reviews cluster around a launch date, which usually indicates a seeding campaign rather than organic use.

How to read commissioned advice usefully

The point is not to dismiss it. Some of the best product writing in Britain is funded this way, by people who work hard and disclose properly. The point is to read it with the mechanism in view.

  • Ask what is missing. Products with no affiliate programme rarely appear. Their absence is not a verdict.
  • Notice the format. A list of ten is a commercial format. A piece explaining a mechanism is usually not.
  • Check whether the piece ever says do not buy this, and whether it ever says buy nothing. Publications that cannot say either are constrained.
  • Follow the link destination. The retailer chosen is a commercial decision, and it may not be the cheapest.
  • Treat gifted and paid content as advertising, which it is, whatever the label says.

And apply the same test to this publication. Our funding is a paid supplier register and newsletter sponsorship, both published with rate cards and with a written list of what the money cannot buy. That is the correct thing to check, and it is set out in full on the about page.

Questions people actually ask

Is affiliate marketing allowed in the UK?

Yes. It is lawful and widespread. The requirement is that the commercial relationship be disclosed clearly and prominently, so that the audience understands it before engaging with the content.

Does commission change what reviewers say?

Frequently not directly. The larger effect is on selection: what gets covered, which retailer is linked, and which formats get produced. Those effects are invisible to readers.

What counts as adequate disclosure?

Disclosure must be clear, prominent and made before the audience engages with the content. A label buried at the end of a caption or in a description is unlikely to satisfy that.

How do I report undisclosed advertising?

Advertising disclosure issues go to the ASA. Broader misleading practices, including fake and incentivised reviews, fall to the CMA and to Trading Standards under consumer protection law.
