The paper presents the findings of the results of the analysis of 127 web accessibility evaluation tools. The research was conducted with the objective to investigate the development and implementation of novel web accessibility tools to maintain constant accessibility of websites. The papers also attempt to investigate the evaluation tools with different dimensions like, automation, crawling, technologies, guidelines, reporting, server capabilities and licensing. The methods used in this study were observation and content analysis of different evaluation tools. The finding indicates that most of the evaluation tools are designed based on HTML technologies and based on WCAG 1.0 guideline. They seem to be taking advantage of the Internet and other Web facilities to provide reporting services to correct the violations. These indicate that the website developers have taken steps to address the guidelines to implement. In order to improve efficiency of the tools, the paper recommends that tool developers should focus on improving crawling capacity of site evaluation; they must engage with the industry mandates. The tools also need to assist website developers with access to affordable privileges. So that, developers can able to use tools and they can develop more accessible websites for disabled people.
