Evaluating the Accessibility, Usability, and Security of Corporate Investor Relations Web Pages: A Case Study of the Turkish Stock Market

This study investigates the accessibility, usability, and security of investor relations (IR) web pages of 53 companies listed on the Istanbul Stock Exchange (BIST), focusing on both BIST-30, representing the most liquid and highly capitalized companies, and BIST-2022, companies that had their initial public offerings (IPOs) in 2022. Using automated testing tools, the analysis examines adherence to the WCAG 2.1 guidelines, mobile responsiveness, and security measures. The findings reveal that accessibility issues, particularly related to the robust and perceivable principles, are prevalent across the assessed web pages, with BIST-30 companies showing a higher rate of errors. While BIST-2022 companies generally performed better in usability, with faster loading times and fewer broken links, security assessments indicated low to medium risks across both categories. This study contributes to the limited literature on the quality assessment of corporate IR web pages and highlights the necessity for enhancements in accessibility, usability and security, providing valuable insights for web administrators and developers to improve the quality of IR web pages.
