Automated scan
A public page rendered by Google PageSpeed Insights and assessed with Lighthouse accessibility rules.
Evidence recorded
Rule, WCAG reference, severity, affected element samples, and remediation guidance.
Methodology and coverage
Automated evidence with a visible boundary.
Reachivo records what was assessed, how it was assessed, and what still needs human judgment. It does not turn a partial automated scan into a certificate or legal conclusion.
Named methods
Three evidence layers, never blurred together.
Planned for the program portal
Guided manual check
Keyboard use, focus order, screen-reader flow, content meaning, and other criteria automation cannot decide.
Evidence recorded
Named method, person, date, page, result, and notes.
Human service
Expert review
A scoped evaluation following an agreed methodology such as WCAG-EM.
Evidence recorded
Reviewed scope, observations, limitations, and dated deliverables.
Current automated engine
What happens during a free scan.
- 1
Validate the target
Only public HTTP or HTTPS pages are accepted; local and private network targets are rejected.
- 2
Render with Lighthouse
Google PageSpeed Insights renders the public page and returns Lighthouse accessibility audit results.
- 3
Normalize and prioritize
Failing rules become severity-first findings; element count orders work within a severity band.
- 4
Attach reviewed guidance
Known rules use Reachivo’s versioned knowledge base, so ordinary scans make no model call.
- 5
Disclose the boundary
The report names automated scope and the manual checks still required.
Coverage boundary
A clean automated result is a good signal, not a complete evaluation.
Automated tools reliably detect roughly a third of WCAG success criteria. The exact set depends on page content and engine behavior; passing rules do not prove the rest of the experience works.
Common human-review work
- Keyboard reachability, traps, and logical focus order
- Screen-reader reading order and control announcements
- Alternative-text quality and content meaning
- Error recovery, instructions, and interaction states
- Zoom, reflow, motion, and complex workflow behavior
