Accessibility tools for website checks
Rapid tests for typical accessibility problems: WCAG and BITV signals, contrasts, alternative texts, link texts, form labels, ARIA, keyboard focus, language, heading structure, landmarks and BFSG preparation. The crawler-based tools automatically find the sitemap, show 10 URLs for free and lead to a joint website audit for all check areas.
WCAG Checker
Technical pre-testing of several WCAG/BITV-oriented signals via sitemap URLs.
Contrast checker
Calculate WCAG contrast ratio for text and background colors.
Alt-Text Checker
Find images without alt attributes and display specific selectors.
Form Label Checker
Recognize input, select and textarea fields without accessible names.
Headings and Landmarks Checker
H1, technically consider heading hierarchy and main landmark.
Linktext Checker
Find empty or non-specific link texts such as “more” and “here” via sitemap URLs.
Keyboard Focus Checker
Check tabindex risks, missing skip links and focusable aria-hidden elements.
ARIA Checker
Detect duplicate IDs, missing ARIA targets, unknown roles, and iframe-title issues.
Language and Title Checker
Check HTML-long, language code and document titles as common SEO and accessibility signals.
Entry aid Checker
Check labels, button names and autocomplete notes for lead and checkout forms.
BFSG Checklist
Structuring preparation, prioritization and next steps for website accessibility.

Tools for barriers that slow down users and sales
Since 28 June 2025, accessibility requirements are relevant for many B2C-related digital services. Especially online shops, booking routes, payment functions, logins and forms should not only be noticed in the manual audit.
The individual tools help to quickly limit typical technical risks. The complete website audit bundles the most important finds over up to 2,500 URLs.
Which accessibility tool fits which problem?
For a quick overview
Use the WCAG Checker or the website audit. This allows you to see if typical technical barriers occur across multiple sitemap URLs.
For visual readability
The Contrast Checker calculates color contrasts for text and background. This is especially helpful for buttons, navigation, hints and form errors.
For content and image pages
The Alt-Text Checker finds images without an alt attribute. This is relevant for editorial pages, product images, teasers, logos and icons.
For leads, login and checkout
The form Label Checker shows fields with no accessible names. Especially with shops and form routes, such finds are often conversion-critical.
For keyboard operation and focus
The Keyboard Focus Checker uncovers technical patterns that can make navigation, modals and CTAs more difficult without a mouse.
For robust components
The ARIA Checker is useful for complex menus, accordions, tabs, sliders and dynamic UI components.
Accessibility tools as a supplement to SEO analysis
Accessibility and SEO are not opposites. A cleanly structured page is easier to use, easier to crawl, and often easier to optimize. Alternative texts, headings, semantic areas, unique link texts and comprehensible forms are equally helpful for users and search engines.
Therefore, the accessibility tools are consciously linked to the existing Seitenreport SEO tools. You can first check technical SEO and then prioritize accessibility finds.
Recommended Workflow
- 1. Check sitemap and technical SEO with the SEO tools.
- 2. Start WCAG checker or website audit for accessibility signals.
- 3. Translate critical findings into tickets and prioritize them by template type.
- 4. After implementation, supplement manual keyboard and screen reader tests.
Accessibility Tools Questions
Are the tools free?
The entry exam is free of charge. Crawler-based tools show 10 URLs and limited finds. The joint website audit with up to 2,500 URLs and exports is available for one-off 99 € net; the SEO suite from 19 € net monthly.
Can I use it to prove BITV or BFSG compliance?
No. The tools provide WCAG/BITV-oriented technical guidance and priorities. A legally compliant proof requires additional manual examination and documentation.
Why are there individual tools in addition to the website audit?
Individual tools cover specific search intentions, such as alt texts, contrast, ARIA, link texts or form labels. The website audit bundles the most important technical checks.
Which inputs work?
Domains such as for example.de Or full URLs work. The tool normalizes the input and then searches for the sitemap.
Which tools are particularly important for online shops?
Form label checker, input aid checker, keyboard focus checker, ARIA checker and contrast checker are particularly relevant for search, shopping cart, login, checkout and payment routes.
Why should I check multiple URLs?
Many barriers arise in templates. A single homepage can seem clean, while product pages, category pages, or forms contain recurring issues.
What do I do with the findings?
Turn the most important hits into tickets, group them by template or component, and then manually check keyboard operation, screen reader flows, and visible focus states.
What role does SEO play?
Clean headlines, alternative texts, clear link texts, understandable forms and robust HTML structure help both users and search engines to understand the page.
