What counts as a dupe?
We use the word “dupe” to describe a product that is being considered as a more affordable alternative to another product. It does not mean that the products are identical. We separate visual lookalikes, similar formulations, products intended to perform similar tasks and generally better-value alternatives. A bag with a comparable outline may have entirely different materials, while two serums containing the same headline ingredient may differ in concentration, delivery and feel.
How we select comparisons
Our editorial team considers reader suggestions, commonly compared products, and questions that reveal a meaningful purchasing decision. We look for specific differences worth investigating rather than publishing every pair that happens to share a colour or trend. Products are not included solely because a merchant provides an affiliate programme.
How information is collected
For desk-researched comparisons, we use manufacturer product descriptions, ingredient lists, size charts, published materials, price listings and credible third-party information where available. We record sources and when key details were checked. When information cannot be substantiated, we say that it is unknown rather than filling the gap with an assumption. We do not present a desk-researched result as if we had held, worn, smelled or tested a product.
Hands-on verdicts require real use or examination with clearly described conditions, limitations and observations. Reader reports are labelled and may help determine which products deserve further review, but they do not automatically become verified findings.
What we compare
The criteria depend on the product type. For handbags we may consider material composition, stitching, hardware, weight, internal layout and maintenance. For skincare, we distinguish shared ingredients from claims about concentration and performance. For electronics and household products, we compare specifications, intended uses, consumable costs, warranty terms and practical constraints. We also assess availability and whether a comparison is meaningful for a shopper in a particular market.
How we reach a verdict
We discuss points of similarity, important differences, reasons to consider the alternative and reasons to choose the original. Our labels describe the evidence available and a qualitative assessment of particular criteria. They are not laboratory scores or a scientific measure of similarity. We do not assign a numerical match percentage without a transparent, defensible calculation.
Price, affiliate links and commercial relationships
Displayed prices are snapshots from the last source check unless otherwise stated. Retail pricing, shipping, taxes, promotions, regional availability and exchange rates change. Prices in different currencies are not silently converted. Affiliate links may earn us a commission at no additional cost to the buyer; sponsored or supplied products must be disclosed in the relevant comparison. Commercial relationships do not entitle a product to a favourable verdict.
Corrections and updates
Readers and brands can request corrections through our contact page. We verify substantive corrections against evidence, update the relevant record, and note meaningful changes when appropriate. An old comparison should not be interpreted as confirmation of current specifications or stock.
