Critical defects cap a site's grade: 3 criticals set a minimum index of 71. Fixing them is the fastest way to a better grade.
Where the faults are
Fault severity by category — 0 means no defects found (clean), 100 means severely broken. These are damage meters, not marks out of 100.
Fault index trend
Daily fault index — lower bars are better; a rising trend means something shipped and broke.

The complete report — including security findings and the evidence behind every defect — is free for the people who run Jack Wills. To keep that detail away from trolls and attackers, we only send it to addresses at the brand's own domain (@www.jackwills.com). Other addresses are reviewed by a human first.
