What is WCAG?
WCAG (Web Content Accessibility Guidelines) is a guideline set published by the W3C and used worldwide as the reference standard for digital accessibility. Rather than a software standard, it's a set of concrete, testable answers to the question "who should be able to use an interface, and under what conditions."
Four principles: Perceivable, Operable, Understandable, Robust
Every WCAG rule rests on four core principles: content must be Perceivable (a visual cue can't rely on color alone — it needs alt text or structure too), Operable (every function must be reachable by keyboard, not just mouse), Understandable (form errors must be explained clearly, navigation must stay consistent), and Robust (it must work with assistive technologies like screen readers, using properly marked-up structure).
Conformance levels: A, AA, AAA
WCAG defines three conformance levels. A is the minimum and isn't considered sufficient on its own. AA is the level public institutions and most corporate regulations reference, and the level practically targeted. AAA is the highest level; since it isn't realistic to fully meet for some content types, it's usually targeted for specific criteria rather than imposed as a mandatory condition site-wide. AA is the core target in our audits.
Why now?
Accessibility is no longer a concern only for public institutions; public tenders, corporate procurement processes, and growing user expectations are making accessibility an increasingly decisive criterion in the private sector too. An accessible product also reaches a wider audience and generally produces fewer usage errors — because a clearly labeled, predictable interface is easier for everyone to understand.
Our audit process
The process moves through five steps: (1) automated scanning with the Accessibility Audit Bot — quickly catches detectable errors like missing alt text, low contrast, and unlabeled form fields; (2) manual keyboard-only navigation testing; (3) manual testing with a real screen reader; (4) a prioritized findings report with remediation recommendations; (5) a verification pass after fixes. Since automated scanning only catches a portion of the errors, steps 2 and 3 are never skipped.
