Web Performance and Accessibility Scores Show Uneven Progress

Recent HTTP Archive technical reports reveal wide variations in web performance and accessibility across public sector websites. Median Lighthouse Accessibility scores and Core Web Vitals metrics are inconsistent, highlighting an ongoing need for vigilant monitoring and regular audits in design operations.

- The European Accessibility Act (EAA) mandates that by June 2025, public sector bodies and many private sector companies doing business in the EU must ensure their digital products and services are accessible. This directive complements the 2016 Web Accessibility Directive, expanding its scope beyond just public sector websites and apps to include e-commerce, banking services, and electronic tickets. - A 2022 pilot study of over 14,000 eGovernment websites across Europe revealed that 84% did not comply with basic Web Content Accessibility Guidelines (WCAG) criteria. The study assessed criteria related to content being perceivable, operable, understandable, and robust, indicating a significant gap in meeting accessibility standards. - The latest standard, WCAG 2.2, was released in October 2023 and introduces nine new success criteria focused on improving usability for individuals with low vision, cognitive or learning disabilities, and motor disabilities, particularly on mobile devices. While WCAG 2.1 Level AA is often the legal standard, adopting 2.2 is considered a best practice to stay ahead of evolving regulations. - Poor website performance directly impacts access to public services, creating barriers for users with cheaper devices or slower internet connections. Core Web Vitals are key metrics for this, with Google recommending a Largest Contentful Paint (LCP) under 2.5 seconds, an Interaction to Next Paint (INP) of less than 200 milliseconds, and a Cumulative Layout Shift (CLS) score below 0.1 for a good user experience. - A UNDP-supported study of digital accessibility in five European countries—Denmark, France, Germany, Sweden, and the UK—was conducted to identify best practices in legislation and institutional capacity that could be implemented in other nations. For instance, countries like Denmark and the Netherlands have shown that a structured approach, including user involvement, leads to higher accessibility levels on public websites. - Artificial intelligence (AI) is increasingly being used to enhance web accessibility through automated auditing, remediation, and continuous monitoring. AI tools can assist in generating alt text for images, analyzing color contrast, simulating keyboard navigation, and even suggesting simpler language to improve readability for users with cognitive disabilities. - Challenges in public sector web accessibility often stem from a lack of staff time, insufficient financial resources, and a need for more training and awareness. To address this, embedding accessibility into the design process from the start, conducting regular usability assessments with diverse users, and choosing technology that adapts to evolving standards are crucial strategies. - Monitoring and enforcement of web accessibility are handled by designated national bodies within each EU member state. These bodies are responsible for periodically checking public sector websites and mobile apps, reporting their findings, and handling user feedback and complaints.
