What is a website accessibility checker?
It is a tool that scans website pages for likely accessibility barriers and helps teams identify what needs review or remediation.
AXS AUDIT GUIDE
Website Accessibility Checker
A website accessibility checker scans a site for likely barriers that may stop disabled people from using content, forms, navigation or key journeys.
AXS Audit is the main route here: it checks WCAG issues, cognitive barriers, rendered visual problems and dynamic interaction risks, then helps teams prioritise fixes.
Check the site
Find likely accessibility barriers and understand where they affect users.
Prioritise fixes
Turn scanning into practical remediation rather than a long generic issue list.
Go beyond baseline WCAG
Use cognitive, visual and interaction signals to understand real user friction.
Direct answer
A website accessibility checker should help teams find and fix barriers
The useful output is not just a score. A strong checker should show what is wrong, who may be affected, why it matters and what the team should fix first.
AXS Audit is built for that workflow: scan the site, understand the issue, group repeat findings, and move towards remediation with clear guidance.
| Question | Simple answer | Why it matters |
|---|---|---|
| What does it check? | Likely accessibility issues. | Teams need a fast way to find barriers before users encounter them. |
| Is a checker enough? | Not by itself. | Important journeys may still need expert review and manual testing. |
| What makes AXS Audit useful? | It prioritises impact, not only rule IDs. | Teams can focus on fixes that matter most to users. |
| Where should users go? | AXS Audit. | This page should move searchers directly to the product route. |
Why AXS Audit
AXS Audit checks more than static HTML
Many scanners focus heavily on static DOM checks. AXS Audit is designed to look deeper: cognitive accessibility scoring, rendered-page AI Vision analysis, keyboard simulation and dynamic content evaluation.
That makes it better suited to modern websites where issues may appear only after JavaScript loads, layout changes or a user interacts with the page.
Practical checks
- WCAG issue detection for core accessibility barriers.
- Cognitive Accessibility Score and Cognitive Load Index signals.
- AI Vision checks for rendered-page image and layout issues.
- Finding-first grouping to reduce repeated developer noise.
