General Information on Accessibility
Implementing accessibility starts with a clear, simple layout and logical navigation, so users can quickly find the information they're looking for. Alt texts for images and video descriptions make content accessible to visually impaired users; clear, easy-to-read fonts and sufficient contrast between text and background are also important.
Another important measure is supporting keyboard operation: users with motor impairments cannot always use a mouse or touchpad and rely on clear keyboard navigation. ARIA labels also help mark up content for screen readers, so people with visual impairments can better understand and navigate content.
Beyond these technical measures, it's important to foster a positive attitude toward accessibility: involving users with disabilities in the development process, as well as regular accessibility testing and audits.
Legal status: Since 28 June 2025, the German Accessibility Strengthening Act (Barrierefreiheitsstärkungsgesetz, BFSG) has also been in force. It extends the obligation for digital accessibility beyond public bodies to many private companies, especially online shops and digital services. We're happy to check whether and which requirements apply to your website.
Accessibility = Search Engine Optimization
Anyone who makes their website more accessible is simultaneously optimizing it for search engines. There are essentially two reasons for this:
- Search engines want search results to be accessible to as wide a range of people as possible – an accessible website therefore usually ranks above an otherwise equivalent, less accessible website.
- Search engine crawlers have no human perception and are extremely limited, especially semantically. Many measures that reduce barriers (e.g. alt text for images) therefore also benefit search crawlers, because they can "understand" the content better.
Standards and Guidelines
The worldwide standard for accessible websites is the Web Content Accessibility Guidelines (WCAG) 2.1. In Europe, the "Accessibility requirements for ICT products and services" apply, which also form the basis of Germany's Barrier-Free Information Technology Ordinance (BITV). Among other things, the BITV defines:
- explanations in German Sign Language and Easy Language on the homepage of a public body
- an accessibility statement that must be provided
- the "highest possible degree" of accessibility for central navigation, entry points, and interactive offerings
- accessibly designed PDF documents
