Conformidade do Portal gov.br à WCAG 2.2: uma análise comparativa com WAVE e Accessibility Insights for Web

Abstract

Web accessibility aims to ensure that people with different types of disabilities can perceive, understand, navigate, and interact with digital content and services in an autonomous and effective way. This study aims to evaluate the accessibility of the GOV.BR portal based on the Web Content Accessibility Guidelines (WCAG 2.2), using automated evaluation tools. The research seeks to identify barriers that compromise the browsing experience of users with disabilities and to propose recommendations that contribute to improving the portal. To achieve this objective, five representative pages of the website were analyzed using the tools WAVE Web Accessibility Evaluation Tool and Accessibility Insights for Web. The analyses revealed issues such as low contrast between text and background, links and buttons without adequate descriptions, form fields without accessible labels, incorrect semantic structure, and absence of alternative text in images. Based on these results, recommendations were developed to address these nonconformities, aiming to increase the portal’s level of compliance with WCAG guidelines and to promote a more inclusive experience for all users. The study reinforces the importance of digital accessibility as a continuous commitment to inclusion and equal access to information.
