Public Scoring Methodology

We only score what we can evidence. UNKNOWN is never silently converted into FAIL.

Status values

PASS = 1.0
PARTIAL = 0.5
FAIL = 0
UNKNOWN = excluded from readiness denominator
N/A = excluded from denominator

Dimension score

Weighted verified status values divided by verified test weight × 100.

Overall weights

Discoverability 15%
Understandability 20%
Actionability 25%
Transaction Readiness 25%
Trust & Identity 15%

Confidence

Evidence coverage and sampled-page depth determine LOW, MEDIUM or HIGH confidence. Lower confidence widens the displayed readiness range. This is a methodological range, not a statistical 95% confidence interval.

Crawl posture

V3.1 uses a maximum six-page HTML crawl budget, same-origin preference, robots.txt awareness, timeouts and response-size limits. It does not perform authenticated or transactional actions.
