This thesis explores how user-centered design and digital marketing strategies can improve the effectiveness, accessibility, and overall engagement of informational websites. Using a structured research and design approach, a conceptual web prototype was created to apply and evaluate principles such as search engine optimization, inclusive user experience design, ethical communication, and thoughtful content planning. Analytic tools were used to assess accessibility, performance, and the quality of the user experience. The findings show that careful design decisions, combined with strong search engine practices, clear metadata, and layouts that prioritize usability, can meaningfully enhance a website’s visibility, credibility, and user engagement. This research contributes valuable insight to the field of business informatics by demonstrating how digital-first design and ethical communication techniques can support user needs as well as strategic communication goals. Overall, the thesis reinforces the importance of integrating user-experience design, accessibility principles, and digital-marketing methods when creating meaningful, trustworthy, and user-friendly online platforms.
