Scheduled accessibility scans involve choosing pages, setting a frequency, and defining where results go — most scan tools offer this scheduling natively.

A single-page scan evaluates one URL; a site-wide scan crawls many pages or a whole domain in one session. Both check the same WCAG criteria at different scope.

Cloud accessibility scans run on a remote server; local scans run on your machine or browser. Both detect about 25% of WCAG issues, with different trade-offs.

Free and paid accessibility scanners check the same WCAG criteria — the difference is scope: paid tools scale across pages, add monitoring, and provide reporting.

Accessibility scan tools map each automated check to specific WCAG success criteria — the depth of that mapping determines how well a tool represents conformance.

WCAG 2.1 AA and 2.2 AA scans produce similar results — the additions in 2.2 are largely outside what automated scanning can detect in the first place.

Automated accessibility scans evaluate WCAG criteria with binary, code-detectable outcomes — about 25% of all WCAG success criteria. The rest require human judgment.

A scan report is the output of an automated WCAG subset check; an audit report is a full human evaluation across all WCAG conformance levels — very different artifacts.

To prioritize accessibility scan issues, rank them by user impact and risk so remediation time goes to the blockers that actually matter, not every flagged item.

Accessibility scan report metrics include total issue counts, severity ratings, affected WCAG criteria, and page- and element-level detail — each for a different use.

Aligning accessibility scan schedule with your deployment cycle means new code gets evaluated while the team responsible is engaged and changes are still fresh.

Continuous monitoring runs accessibility scans automatically on an ongoing schedule; periodic scans run at set intervals and miss issues introduced between them.
