MWITA-IMO-2026-008 · Evidence B · P1
In 50 leading global e-commerce sites, no site reached WCAG AAA; 83.1% of classified barriers were perceivable, with contrast the dominant error, and commercial rank correlated only weakly with barriers.
What this does not establish
Homepage-oriented automated audit from the pandemic period; compliance class is not checkout success, conversion, purchase, revenue or legal conformity certification.
Counterevidence & uncertainty
High commercial rank did not imply high accessibility, and the most accessible site still only establishes an automated scan result, not successful disabled-user journeys.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral, commercial or welfare outcomes.
