Our rankings aren't editorial opinion, and they aren't paid placement — no brand can buy a guaranteed spot or a higher score. They reflect what shoppers across our network actually do (which products they compare and which they ultimately buy), objective factors like features, price, and availability, and the commercial relationships that keep this site free — our monetization is one of the inputs to what appears and where.

Nothing here is guaranteed or permanent: as new data comes in we re-rank, so today's leaders have to keep earning their spot against new entrants. See how we rank for the full method.
