Comparison of Accessibility Tools for the Evaluation of E-Commerce Websites

Accessibility is an aspect that should be considered when building software products. All people have the right to access the interactive systems that exist in the market. Even in certain countries, there are laws and government regulations that guarantee access to new products and services to citizens with different abilities and capabilities. This fact has generated a current growing concern on the part of companies to provide accessible applications, especially in the web domain where competition is high. Likewise, the importance of accessibility has led to establishing standards and guidelines to ensure minimum considerations in the development of software products. The W3C provides a list of tools that automate the accessibility evaluation process according to international standards. This study aims to compare the results offered by five tools when used to inspect the accessibility of e-commerce websites. The results show that differences are depending on the tool that is employed.
