How scoring works

Evidence first, opinions last

Every score is rebuilt daily from the same inputs, so a vendor cannot buy its way up the board.

Certificate coverage

How much of a catalog has third-party certificates that actually resolve at the testing lab.

Pricing depth

How many products have tracked, current prices we can compare across the market.

Trust signals

Independent review scores contribute as bonus signals, never as gatekeepers.
