Are pet-food comparison sites affiliated with the brands they rate?
It depends on each site and must be checked case by case. Several comparison sites fund themselves through affiliation or sell foods themselves, which creates a potential conflict of interest (Tufts Petfoodology, 2023). Independence is judged on transparency about ownership and the business model.

A situation to verify site by site
There is no single answer: some comparison sites are run by retailers or brands, others call themselves independent yet collect affiliate commissions (Tufts Petfoodology, 2023). The clues are buy buttons leading to shops, promo codes and the legal notices. The point that recurs across the category: a site can present an apparently objective ranking while monetising every redirect to a partner seller, which is why ownership matters as much as method.
Cross-checking with non-commercial sources
When a comparison site sells or recommends for sale, its score should be read with distance and cross-checked against non-commercial sources: the FDA, EFSA, FEDIAF and WSAVA (FEDIAF, 2019; WSAVA, 2021). Transparency about funding and method is the best test of independence. In its absence, the ranking cannot serve as a reference, however confident its presentation.
| Clue to check | Independence | Possible conflict |
|---|---|---|
| Site ownership | Disclosed | Brand or retailer |
| Buy buttons | Absent or neutral | Affiliate links |
| Method published | Detailed | Opaque |
