Accessibility and Performance Evaluation of Healthcare and E-Learning Sites in India: A Comparative Study Using TAW and GTMetrix

Websites constitute a vital role in the development of the technological world. The utilization of online platforms is increasing rapidly in healthcare and e-learning sites. So, it becomes necessary to appraise the accessibility and performance of these sites to ensure universal access and practical use. This paper intends to inspect ten websites from two different domains in which the first five are healthcare sites, whereas others are from e-learning sites. A tool named TAW is used for accessibility evaluation in terms of perceivable, operable, understandable, and robust against the conformance of WCAG 2.0 level AA. In addition, GTMetrix is utilized to test the performance in terms of page speed metrics. The results show that both domain sites cannot fulfill the minimum requirements of accessibility. However, E-learning sites performed better than healthcare sites concerning performance perspective. Moreover, some suggestions are recommended to improve the lacking factors in accessibility and performance of the sites. Furthermore, this work can be extended by employing an intelligent accessibility tool based on AI-powered methodology like machine learning technologies.
