Every day, humanity is witnessing digital transformation, which involves implementing digital technologies to transform business processes and services from non-digital to digital. The success of this transformation is measured by the Digital Quality of Life (DQL) Index, and VPN service provider Surfshark publishes the study results. As Index DQL grows, so does the number of users because digital accessibility is becoming more popular daily. The increase in digital information, the continuous development of IT, and the transition of life online require software to be accessible to people with disabilities. There is a question about the correlation between software availability level and Index DQL. This research is dedicated to the solution to this issue. Ten European countries were randomly selected, and automated testing of the accessibility of government websites was carried out using the following tools: Tenon, Wave, and SiteImprove. The term Web application accessibility index was defined. For the first time, an analysis of the correspondence between Index DQL indicators and the web application accessibility index was carried out. Even though the EU countries and their partner states are constantly working to improve conditions for people with disabilities, a high DQL Index does not indicate a high level of accessibility of state websites, which was confirmed by the study.
