The SEO boost through accessibility: Why Google favours inclusive websites

For a long time, digital accessibility was primarily seen as an annoying obligation or as an issue limited to the social sector. But in 2026, the tide has turned: accessibility has become one of the strongest levers for search engine optimization (SEO). Google has delivered on its promise to place user experience (UX) at the very center of its ranking system. Websites optimized according to the guidelines of WCAG 2.1/2.2 and the BFSG now enjoy a significant advantage in search results.

Why accessibility increases visibility

Semantic HTML and search engine crawlability

Search engine bots and screen readers read code in almost identical ways. An accessible website uses a clean, semantic HTML structure. Clear hierarchies created through headings not only help people with visual impairments to navigate, but also signal clearly to Google which content is most important. Features such as highlighting titles support this structure both visually and technically.

Core Web Vitals and usability

The Core Web Vitals are the ultimate benchmark for page experience in 2026. Accessible pages are often leaner and more stable in their code. A key factor here is the avoidance of unexpected layout shifts. Tools such as the animation stop not only prevent health risks – as described in our article Epilepsy prevention on the web—but also create a calmer experience that Google rewards with better evaluations of user interaction.

Strategic advantages for your marketing

Lower bounce rates through inclusion

A website that is difficult to consume for people with ADHD or dyslexia loses valuable traffic. As we explained in our guide ADHD on the web – how to stop visual distractions, a low-stimulus environment leads to longer time on site. The same applies to typography: the dyslexia mode significantly improves readability, increasing user retention—an engagement signal that Google directly rewards with better rankings.

Reaching new target audiences

Accessibility means market expansion. People with color vision deficiency need specific contrasts to perceive products in an online shop at all. Intelligent solutions such as the color vision deficiency filter or high contrast mode ensure that you do not lose customers to your competitors. You can learn how to address these audiences more effectively in our article Color blindness is not all the same.
