live factor #53 · Accessibility · scoring impl: implemented · weight 2.7%

What we measure

Accessibility scanners flag concrete WCAG violations: missing labels, low contrast, broken keyboard navigation. Each issue is a real exclusion of disabled users — not a theoretical compliance question.

How to improve your score

Run axe-core (or Lighthouse) against your site and fix the reported issues. Most are 5-minute fixes — adding labels, adjusting colors, fixing tab order.

Data source

Data source for this factor is not yet documented.

Implementation notes

Already in PSI accessibility audits — just expose the issue list with severity and node selector.

Scoring

Scoring formulas are versioned with the methodology. The current method (v1.1.0) maps raw measurements to pass, warn, fail. Factor weights determine how much each contributes to the composite — see the methodology index for the full table.
