Towards Improving Accessibility of Web Auditing with Google Lighthouse

Google Lighthouse is a tool made by Google for auditing web pages performance, accessibility, SEO, and best practices with the intention of improving the quality of the websites. This allows software developers to understand areas of improvement within a website. However, accessibility becomes an issue when it comes to rapidly handling multiple input for generating performance report consisting different formats with better accuracy. In this work, a test on set of improvements to enhance the reference Google Lighthouse architecture was conducted to enable it to process multiple file input types with the focus of producing different output format including better accuracy. Multiple experimental runs involving different size of file input were conducted by comparing the results from using the modified Lighthouse with the original Lighthouse. The results proves the feasibility of the enhancement and can further improve the accuracy of performance audit report with known Lighthouse performance metrics.
