Exploring Common Usability Methods and Their Application in Website Optimization

Website usability is a prominent factor in determining user experience, interaction, and business success. With web platforms becoming more complex, the necessity for systematic usability testing becomes more critical. This paper discusses five commonly used usability methods - Heuristic Evaluation, System Usability Scale (SUS), Eye Tracking, A/B Testing, and Usability Testing - outlining their processes, strengths, weaknesses, and real-world applications. Based on recent research and best practices in the field, the paper identifies how every approach contributes in a distinct way to the detection of usability problems and the development of optimization strategies. The results point out that choosing the right evaluation approach is a matter of project objectives, budget, and the phase of development, and that strategic integration of multiple approaches can result in more user-friendly, user-centered web design.
