Our automated scan tests a wide range of WCAG 2.1 and 2.2 success criteria to flag the most common accessibility barriers.
Images & alt text
Checks that all meaningful images have descriptive alternative text and that decorative images are hidden from assistive technology.
Colour contrast
Measures foreground and background colour contrast ratios against the WCAG AA minimum (4.5:1 for body text, 3:1 for large text).
Keyboard navigation
Identifies interactive elements that are unreachable by keyboard and missing or incorrect focus indicators.
Form labels & errors
Verifies that every form field has an accessible label and that error messages are programmatically associated with the relevant input.
Heading structure
Reviews the heading hierarchy to ensure a logical reading order that makes sense for screen reader users navigating by heading.
ARIA usage
Validates that ARIA roles, states, and properties are used correctly and that landmark regions are present and labelled.
Automated scanning only goes so far
Automated tools reliably catch around 30–40% of WCAG issues. The rest — broken keyboard journeys, confusing reading order, inaccessible custom components, and real user experience barriers — require human review.
If your scan reveals issues, or if you need a thorough audit for compliance purposes, our team conducts full manual WCAG audits with assistive technology testing.
