Automated accessibility checkers use WCAG accessibility standards to check your site’s code for accessibility issues, like missing alternative image descriptions, missing ARIA labels, or colour contrast issues.
Examples of these kinds of accessibility tools include Lighthouse, AxE, SiteImprove, Firefox Inspect, Microsoft Accessibility Insights, and many others. These tools are focused on code and technical compliance. They do not test for usability, inclusivity, or comprehensive screen reading capabilities.
Using automated accessibility checkers alone to improve your accessibility will not ensure a wonderful user experience. That’s why we developed the Essential Website Audit service.
