WCAG
The Web Content Accessibility Guidelines: the international standard with testable guidelines for accessible websites.
By Tanguy De Keyzer · Founder & digital strategist
WCAG stands for Web Content Accessibility Guidelines and is the international standard that describes how to make a website accessible to people with a disability.
What the guidelines cover
WCAG bundles concrete, testable criteria around four principles: content must be perceivable, operable, understandable and robust. In practice this concerns sufficient colour contrast, operation with the keyboard alone, text alternatives for images and a logical structure that screen readers can follow. The criteria are divided into three levels, A, AA and AAA, with AA being the benchmark for most sites. The nice thing is that the rules are measurable, so you know objectively whether your site meets them.
Why WCAG became legally important
WCAG is no longer optional. The European Accessibility Act (EAA) made digital accessibility a legal obligation within the EU from June 2025 for many services and products. Anyone who runs a website or web shop that falls under that law must demonstrably comply. For B2B organisations this means: accessibility is no longer a nice-to-have but a requirement you can be held to.
WCAG as the basis for a better site
Meeting WCAG is more than covering risk. The same measures that make your site accessible, such as clear microcopy, a tidy navigation structure and a design that scales via responsive design, improve the experience for everyone and support your conversion rate. We therefore view accessibility as an investment in quality, not as a mandatory formality.
