Why the same shop suddenly seems to be linked everywhere

Spotting affiliate links helps you understand why a blog article, a video or a social media post points to the same shop remarkably often. An affiliate link, also called a partner link, is a link through which the site owner earns a commission if you reach a shop via it and order something there. It is a widespread, legal model that blogs, comparison sites and individuals use to fund themselves, without you paying anything extra. How this mechanism works in detail, from the click to the commission being credited, is described in the article How affiliate marketing works.

Knowing how to recognise such a link mainly helps you put a recommendation into context, not to distrust it automatically.

How to recognise a partner link in the URL

Many affiliate links contain an extra section in the web address that has nothing to do with the product itself, such as an abbreviation like "ref", "aff" or "tag", or a long string of numbers and letters after a question mark. Some sites also redirect the link through their own, shorter address before it reaches the actual shop, which you can often see in the browser's status bar when you hover the mouse over the link, before you even click.

Disclosure: notices you will find in the text

In many countries, sites that earn money from partner links have to make this clear, usually with a short notice such as "affiliate link", "advertising", "ad" or "contains affiliate links" at the beginning or end of a post. This notice is sometimes prominent, but sometimes only appears in small print at the bottom of the page or in a general disclaimer that covers the whole site rather than the individual post. The exact rules differ from country to country. If there is no disclosure at all, even though the same shop is linked remarkably often, that is no proof of a partner link, but it is a reason to look more closely.

Why a recommendation with a partner link is not automatically dishonest

• The commission comes out of the shop's marketing budget, not from a mark-up on the price you pay.
• A shop normally only pays if the click actually turns into a completed order, not for the click alone.
• Many reputable comparison sites and specialist publications fund themselves wholly or partly through such links, which does not rule out editorial independence.

So a partner link does not normally change the price you pay. What is worth questioning is rather whether a recommendation is backed up with reasons that make sense, or whether a product keeps appearing in first place for no obvious reason. Why some sites can be offered free of charge at all, even though keeping them up to date takes work, is explained in the article Why a discount code site can be free for you.

An example of comparing prices

Say a pair of headphones costs 89.00 euros according to the shop's own product page. You find the same headphones linked in a blog article that is clearly marked "affiliate link". If you open the link, the product page also shows 89.00 euros, with no mark-up at all. If you type in the shop's address directly instead, without going through the partner link, the price stays exactly the same at 89.00 euros. The only difference is that in the first case the shop pays the blog a commission once you order through that link.

When a second look is still worthwhile

Things get more questionable when a site only promotes the products with the highest commission rate, whether or not they fit the topic, or when a review sounds strikingly one-sided and positive without mentioning a single drawback. Frequently changing "best of" lists that keep putting the same shop in first place without naming clear criteria also deserve more scepticism than a recommendation with a well-reasoned selection and visible disclosure.

Why a click does not lead to a commission straight away

Between clicking an affiliate link and the commission being credited, there is usually a time window, the so-called cookie duration, often between one day and several weeks depending on the shop's programme. If you order within this window, even if you closed the site in between and opened it again later, the order is usually still attributed to the original link. If, on the other hand, you click another partner link for the same shop in the meantime, for example from a different site, the most recently clicked link usually takes over the attribution, not the first one. For you as a buyer this has no effect on the price; it only decides which site ends up receiving the commission.

What sets affiliate links apart from other forms of advertising

Unlike traditional banner advertising, which a shop pays for regardless of the result, an affiliate commission depends directly on a completed order. That gives sites that live from it an incentive to create content that genuinely helps people buy, rather than just generating as many clicks as possible. For you as a reader, though, the basic rule stays the same: a price reached via such a link is normally identical to the price you see when you go to the shop directly. The How it works page on daily-coupons.info also sums up the basics around codes and links.

Frequently asked questions

Do I pay more for a product via an affiliate link?

Usually not. The commission comes out of the shop's marketing budget and is not added to the product price. The price via a partner link normally matches the price you see when you go to the shop's site directly.

Does a site always have to disclose affiliate links?

Many countries have such a disclosure requirement, usually met with a notice such as "advertising" or "affiliate link" in the post or in a general disclaimer on the site. The exact rules vary by country, and how sites put them into practice varies too.

What is the quickest technical way to recognise an affiliate link?

Often by an extra section in the web address after a question mark, or by the link first redirecting through a different, shorter address before it reaches the actual shop. A look at the status bar when you hover over the link often shows this before you click.

Is a recommendation with an affiliate link automatically less trustworthy?

Not automatically. What matters more is whether the recommendation is backed up with sound reasons and whether several products are compared fairly, rather than only the product with the highest commission being promoted.
