Ensuring digital accessibility is essential for inclusive access to online services. However, many government and non-government websites that provide critical services - such as education, healthcare, and public administration - continue to exhibit significant accessibility and usability barriers. This study evaluates the accessibility of Bangladeshi government and non-government websites under WCAG~2.2 by combining automated accessibility assessments with user-reported feedback. A total of 212 websites were analyzed using multiple automated tools, complemented by a survey of 103 users to capture real-world usability, accessibility, and security experiences. The results reveal substantial disparities between government and non-government websites, highlighting persistent issues related to navigation complexity, interaction cost, visual readability, accessibility feature adoption, and authentication mechanisms. While non-government websites generally demonstrate better usability and functional performance, accessibility support remains inconsistent across both categories. The findings underscore the need for regular accessibility audits, user-centered design practices, and policy-driven interventions to improve digital inclusivity and ensure equitable access to online services for diverse user populations.
