Accessibility

Accessibility is key.
Are you accessible?

Accessibility and usability belong together – just like doors and access. If a door is closed, people can’t enter. If a website isn’t accessible, people can’t use it. Accessibility requirements are evolving. So we evolve monitoring.

The way we test

Websites come to life in the user's browser – not on the server. The server only delivers the building blocks. How a page actually looks, behaves and performs is determined in the browser. Anyone testing only on the server is checking the plan, not the result. Whether a page truly works becomes visible on the screen where it appears. That's where we look.

BFSG is law.

The Barrierefreiheitsstärkungsgesetz (BFSG) is requiring private sector websites to meet WCAG 2.1 AA since June 28, 2025.

Automatically testable WCAG 2.1 AA accessibility criteria

Automated accessibility testing can detect only part of the WCAG requirements. The following criteria belong to the technically testable rules where automated checks can identify common violations.

Perceivable

1.1.1Non-text content: alt text for images, charts, buttons
1.3.1Info and relationships: form labels, table headers, heading structure
1.3.2Meaningful sequence: reading order via DOM
1.4.3Contrast: text/background ratio ≥ 4.5:1
1.4.4Resize text: no viewport meta blocking scaling
1.4.10Reflow: no horizontal scrolling at 320px
1.4.11Non-text contrast: UI components, icons

Operable

2.1.1Keyboard: all interactive elements reachable without mouse
2.1.2No keyboard trap
2.4.1Skip navigation blocks
2.4.4Link purpose: non-generic link text
2.4.6Headings and labels: descriptive
2.4.7Focus visible
2.5.3Label in name: button/link text matches accessible name
2.5.5Target size: minimum 24×24px

Understandable

3.1.1Language of page: lang attribute present
3.1.2Language of parts: language switches
3.3.1Error identification
3.3.2Labels and instructions

Robust & BFSG-specific

4.1.1Parsing: valid HTML structure
4.1.2Name, role, value: ARIA implementation
4.1.3Status messages
Accessibility statement present and up-to-date (BFSG § 12)
Feedback mechanism accessible
