In the digital age, the accessibility of websites, understood as the preparation of digital tools for the use of them by people with disabilities, is becoming an increasingly fundamental right. Web Content Accessibility Guidelines (WCAG) audits play a key role in assessing how websites and mobile apps are accessible to users with different needs.
