What does this grade mean?
The website is the front door a buyer actually meets. We score it precisely and reproducibly — a fixable read of a factory’s digital operations, not a verdict on the company. Weak digital ops track with slow replies and thin documentation; a strong score is a signal you can act on. Method ↗
