Web accessibility performance analysis using web content accessibility guidelines and automated tools: a systematic literature review

Web accessibility is expressed as the ability of all target users, including the disabled, to access, use, understand and interact with the website. This study aims to systematically review the literature on automated tool utilization in web accessibility research. A comprehensive review was carried out covering the last two decades from 2002 to 2021. 72 articles were reached from widely used databases by using a search strategy. These identified articles were classified according to publication type, publication year, publisher, automated testing tool, website type, and accessibility guide. The findings show an increasing trend in its use in web accessibility evaluations with the popularity of automated testing tools year by year. We hope that this literature review and classification will provide an overview of research on web accessibility analysis using automated testing tools, and present as a roadmap to guide future research in this area.
