What the Analyzer specifically checks

Images & Media

Each check includes a technical analysis, WCAG reference, practical explanation, and actionable recommendation.

image-alt – alternative texts present

Screen readers rely on alt texts to read image content aloud. Google also uses these texts for image SEO.

image-title – title attributes set

Titles provide additional context information, for example for tooltips and assistive technologies.

iframe-title – iFrames labeled

Embedded content such as videos or maps must be clearly described so users can understand their purpose.

Structure & Semantics

heading-structure – correct headings

Clear hierarchies (H1 → H2 → H3) provide navigation for screen readers and a table of contents for search engines.

logical-order – logical reading order

The DOM structure matches the visual presentation – essential for screen reader and keyboard users.

html-valid – valid basic structure

Error-free HTML prevents display and compatibility issues with assistive technologies.

html-lang – language attribute set

Screen readers use the lang attribute to select the correct pronunciation and voice.

Forms

form-labels – fields labeled

Every input field needs a real – placeholders alone are not sufficient. Crucial for conversions.

accessible-name – WCAG 2.5.3

Buttons and controls have a unique, machine-readable name for screen readers.

Contrast & Text

contrast-min – sufficient contrast

Minimum contrast ratio of 4.5:1 for body text according to WCAG 1.4.3.

contrast-enhanced – large text

For large text, 3:1 is sufficient – important for buttons and teasers.

text-resize – scalable

Content remains usable up to 200% zoom without loss of functionality.

Keyboard & Focus

keyboard-access

All functions can be operated without a mouse.

no-keyboard-trap

Focus can leave any area again at any time.

skip-link present

Users can skip navigation and jump directly to the main content.

Links & ARIA

link-purpose descriptive

Links such as “Read more” are not clear without context.

internal links correct

Targets exist, are focusable, and are meaningfully named.

aria-roles valid

Roles comply with the specification and do not create conflicts.

aria-live status messages

Dynamic content is correctly announced to assistive technologies.
