Inclusion is important, even in the digital world. The new Accessibility Reinforcement Act (BFSG) no longer only obliges federal public bodies to ensure accessibility, but also private companies to make digital access to their products and services accessible from June 28, 2025. This applies in particular if products or services can be purchased via the website. But what requirements must be implemented in an accessible website? Which technologies are used? And how compatible are your own technical systems such as CMS & Co. with them? In our article, we provide a quick introduction to the topic of accessibility and explain what to look out for.
One website for all
Seven steps to an accessible website

1 Definition: What is an accessible website?
An accessible website is a website that is designed in such a way that it can be easily used by all people, regardless of their physical or mental abilities. The aim of accessibility is to provide all users with equal access to the information and functionality of the website.
Implementing accessibility on the web is not just a legal obligation. It also offers the opportunity to improve the comprehensibility of your own website as well as its SEO ranking and thus reach more users. At the same time, increased user-friendliness and accessibility benefits all users and can also mean a competitive advantage.
2. target groups: Who needs an accessible website?
Accessible websites are essential for the following groups:
- People with disabilities, including visual, hearing and mobility impairments
- Older people with age-related limitations
- People with technical limitations, such as slow internet connections
- People with reading difficulties or cognitive impairments
- Temporarily restricted persons, such as someone with a broken arm

3. legal obligations: Which companies and institutions must offer an accessible website from June 2025?
The Accessibility Act (BFG) comes into force in June 2025. It obliges the following companies and institutions to provide accessible websites:
- Public institutions: All state and municipal administrations, schools, universities and libraries.
- Public service companies: This includes companies in the areas of public transportation, energy supply, telecommunications and healthcare services.
- Service providers: Banks, insurance companies and other service providers that fulfill essential social functions.
- E-commerce and digital platforms: Online retailers and operators of digital marketplaces.
These companies and institutions must ensure that their websites and mobile applications meet accessibility requirements in order to provide all users with equal access to their services and information.
4 The basic principles: What are the requirements for accessible websites?
The technical requirements for accessible websites are defined in the Web Content Accessibility Guidelines (WCAG) 2.1, which are internationally recognized. The guidelines are based on four pillars:
The four principles of accessibility
- Visual accessibility: Content must be presented in such a way that it can be perceived by users. In addition to customizable font sizes and sufficient contrast between text and background, this also includes alternative texts for images or subtitles for multimedia content.
- Usability: Users must be able to navigate and operate the website. This includes comprehensible and consistent navigation elements as well as the ability to navigate using the keyboard.
- Comprehensibility: The content and operation of the website must be understandable. This includes, for example, clearly structured content and the use of clear and simple language.
- Robustness: The content of the website must be compatible with different browsers and assistive technologies such as screen readers.
5 Technical requirements: What needs to be considered during technical implementation?
The following points are essential when designing accessible content:
- Clear, standard-compliant HTML structure and navigation: semantically correct HTML headings (h1, h2, h3) and lists for structuring the content
- Responsive design for different end devices: The design must adapt flexibly to a variety of different device types.
- Colors and contrasts: Ensure sufficient color contrasts and avoid using only colors to convey information.
- Visibility and legibility: Sufficient contrast between text and background, customizable font sizes.
- Alternative text descriptions for images and graphics: Provide alternative texts (alt tags) for images to describe their content.
- Descriptive links: Avoid vague link texts such as “click here”; instead use descriptive texts such as “find out more about our services”.
- Forms: Design of forms with clear labels and instructions for the input fields and operating elements.
- Subtitles and transcripts for audiovisual content: Transcripts or subtitles should be provided for audio or audiovisual content.
- Avoidance of barriers: These include, for example, flashing elements or automatic redirects.
- Compatibility with assistive technologies: This includes, for example, screen readers, for which the correct use of ARIA attributes is important.
6. process: How does an accessible website relaunch work?
A web relaunch to create an accessible website typically involves the following steps:
Phases of an accessible website relaunch
1. analysis and planning
- Analysis: Evaluation of the existing website for barriers and identification of areas for improvement.
- Planning: Definition of accessibility goals and requirements based on WCAG guidelines.
2. design
- Concept: Creation of an accessibility concept, definition of the accessibility level to be implemented (A, AA or AAA)
- Design and development: Creation of designs and prototypes with accessibility in mind. Implementation of the website with a focus on accessible technologies.
3. implementation
- Technical implementation: Consideration of technical requirements, implementation of accessible functions and content
- User testing: Conducting tests with different user groups and assistive technologies, including tests with people with disabilities. Use of automated and manual testing methods to ensure accessibility.
- Launch: Publication of the new website and continuous monitoring and feedback mechanisms for further improvement.
4. after the launch
- Constant optimization: Continuous monitoring and improvement of accessibility
7. testing tools: Which software can I use to test the accessibility of my website?
The following tools can be used to check the accessibility of a website:
- Figma Extension strong
- WAVE – Web Accessibility Evaluation Tool: Good free API that can be used via browser extensions, e.g. for Chrome, Firefox or Edge. It checks websites for accessibility and provides suggestions for improvement.
- Axe DevTools: A browser add-on that helps developers identify and fix accessibility issues directly in the development environment.
- BITV test
- Color Contrast Analyzer
- Lighthouse: An automated open source tool from Google that performs audits for performance, accessibility and SEO.
- Screen readers such as JAWS, NVDA: Assistive software that can be used to test the user experience of visually impaired users.
By using these tools and complying with the WCAG guidelines, website operators can ensure that their digital offerings are accessible and usable for all users.
It is important to note that automated testing alone is not sufficient to ensure complete accessibility. To achieve good results, we recommend testing with people with disabilities to consider real user needs and assess whether the concept achieves the desired results.
It is also important to see the topic of website accessibility as an ongoing process, not a one-off sprint. If you take the topic seriously, you should include regular reviews, adjustments and optimizations in the planning of your digital strategy.
