WCAG Checker for Websites

Automatically checks the sitemap of a website for typical WCAG-oriented technical signals. 10 URLs are visible for free, additional checking areas and up to 2,500 URLs are offered by the complete website audit.

What does the WCAG Checker check?

The WCAG Checker is a rapid technical test for common accessibility problems. It searches for missing alternative texts, form fields without accessible names, blank buttons, weak link texts, missing page language, H1 problems, header jumps, duplicate IDs, ARIA reference errors, skip link risks, focusable aria-hidden elements and missing landmarks.

The test is deliberately automated and suitable for prioritization. It does not replace a complete manual WCAG check, but quickly shows which templates should be improved first.

When does the website audit make sense?

Before a relaunch or redesign to detect accessibility risks early on.
For shops, SaaS websites and lead routes with many recurring templates.
As preparation for a manual WCAG/BFSG audit by experts.
For agencies that want to quickly show customers a prioritized action plan.

Correctly classify automatic WCAG test

Automated checks find technical patterns quickly, but not every WCAG request is machine-decidable. The benefit lies in the prioritization: Repeated template errors become visible before a manual review goes into details.

Prioritisation in practice

First fix global template errors, then follow individual pages
Complement Findings with Keyboard, Screen Reader and Content Checking
After implementation, crawl again and compare the same URL groups

Next meaningful check

Thus, the examination becomes an iterative quality process instead of a one-time snapshot.

When Automatic WCAG Finds Are Critical

Automatic finds are especially valuable if they appear repeatedly on templates. A single pattern in the navigation, form, footer or tool component can affect the usability of many pages simultaneously.

Not every WCAG point is fully testable by machine. Therefore, automatic results should serve as prioritization and then be compared with keyboard, screen reader, content and real user paths.

Practical example · for illustration

Starting position

Check a contact page with input fields and submit button.

Classify the findings

A missing accessible name is automatically recognizable; if hints and error messages are comprehensible, additional control checks are required.

Specific amendment

Connect the field with a suitable label and assign error messages to the field.

Control and border

Using the keyboard and screen reader, test the entire process including invalid inputs. An inconspicuous automatic check is not a WCAG proof of conformity.
