How often do product scores and rankings update?
Short answer
Scores recompute weekly, and immediately whenever a certification is added, lapses or is revoked, a recall is published, or a documented controversy is added to a brand's record. Rankings on category pages are generated at request time, so the order you see always reflects the current data.
The detail
Because the list is generated live rather than hand-maintained, a page you bookmarked can reorder between visits. That is intentional — a static 'best of' list decays the moment a certification expires.
Editorial framing — the intros, trade-off notes and buying advice — is reviewed each quarter, so the prose and the data update on different cadences.
