Perceivable
Information must be presented in ways users can perceive.
- 01 Text alternatives for images
- 02 Captions in videos
- 03 Adequate color contrast
- 04 Content adaptable to different formats
WCAG 2.1 AA criteria and EN 301 549 standard
Complete and up-to-date list of web accessibility conformance criteria based on WCAG 2.2 (W3C), the basis for EN 301 549 and RD 1112/2018.
One in six citizens lives with some type of disability. When a website does not meet accessibility criteria, real barriers appear: people cannot purchase, request a service, complete a procedure, or access essential information.
Digital accessibility is not just a legal obligation; it is a responsibility and an opportunity. Here you will find all WCAG 2.2 Level AA criteria, explained from the official standard and applicable to public administrations and private companies.
Companies and public organizations committed to accessibility already trust us to make their projects and their clients' projects more accessible
The 4 WCAG Principles (POUR)
We evaluate web accessibility based on the 4 fundamental pillars of the W3C Web Content Accessibility Guidelines, ensuring comprehensive compliance.
Operable
User interface components must be operable by all users.
- 01 Full keyboard navigation
- 02 Enough time to read
- 03 No content that causes seizures
- 04 Navigation and orientation aids
Understandable
Information must be presented in ways users can understand.
- 01 Clear and readable text
- 02 Predictable content
- 03 Help to prevent errors
- 04 Clear instructions and labels
Robust
Content must be robust to work with diverse technologies.
- 01 Valid HTML code
- 02 Compatible with screen readers
- 03 Component identification
- 04 Correct semantics

Official WCAG-EM (W3C) accessibility audit methodology
We follow WCAG-EM, the official W3C methodology to evaluate web accessibility. It is a structured process that guarantees comparable, reproducible, and valid results for any external audit.
01
Initial diagnosis
We define the scope, which pages, which functionalities, and which technologies. We identify critical user flows and select a representative sample according to WCAG-EM.
02
WCAG audit
We evaluate each page in the sample against the 50 WCAG 2.1 AA criteria. We combine automated tools with expert manual review to detect what machines do not see.
03
Solution design
We document each issue with visual evidence, affected code, and a proposed solution. We prioritize by user impact and implementation effort.
04
Guided implementation
We support your technical team during remediation. We review code, validate solutions, and answer questions. We do not leave you alone with a PDF.
05
Final validation
We re-evaluate the corrected pages to confirm compliance. We generate the accessibility statement ready to publish.
Accessibility from start to finish
We don't just identify problems: we provide you with the tools, documentation and knowledge needed to ensure regulatory compliance. We facilitate compliance without overloading your team.
