Are kibble comparison sites really independent of the brands?
Not always. Some comparison sites are owned by brands or paid through affiliation, which creates a structural conflict of interest (Tufts Petfoodology, 2023). Independence is verified through transparency on ownership, business model and scoring method, which is rarely spelled out.

The conflict-of-interest risk
A comparison site paid through affiliate links earns a commission on the sales it drives, which can tilt the scores toward the products that fund the site (Tufts Petfoodology, 2023). That model creates a bias worth spotting. The detail to watch: a site can look neutral while being run by a brand or a retailer, with that fact tucked away in the legal notices where few readers ever look.
How to assess independence
Tufts Petfoodology warns against assessments that explain neither their method nor their funding (Tufts Petfoodology, 2023). A credible comparison site publishes its methodology, its sources and its business model. The WSAVA reminds readers that the reference checklist stays the manufacturer assessment, not a third-party score (WSAVA, 2021). Without transparency, a score loses any evidential value and should not move a decision.
| Signal | Likely independent | Possible conflict |
