What it checks
Color contrast
Text that’s hard to read, measured against WCAG’s 4.5:1 ratio.
Forms
Fields without labels, wrong input types and missing autofill.
Headings and landmarks
A logical outline that screen readers can navigate.
Images and controls
Missing alt text and buttons or links without a name.
Zoom and tap targets
Pages that block zoom or have targets too small to tap.
Accessibility score
Lighthouse’s 0–100 score, with every failed audit listed.
Questions
Does a perfect score mean my site is accessible?
No. Automated tests catch about a third of problems. They’re a great start, but also try your site with a keyboard and a screen reader.
Which standard do you test against?
Lighthouse’s accessibility audits, built on axe-core and mapped to WCAG 2.2 level AA rules, plus our own checks for forms, link text and zoom.
Is accessibility a legal requirement?
In many places, yes. The European Accessibility Act applies to many online businesses from June 2025, and US courts often apply the ADA to websites.
