Designers and developers may not realize how people with different disabilities access websites. People may use assistive reading technology, mouth sticks, Braille keyboards, or a combination of technology. And some website visitors may just need to see high-contrast text and images to help them interpret content.
With accessibility testing tools, you can begin to learn what areas of your site might be confusing or inaccessible to users with disabilities. These tools can help you bring your site into compliance with modern accessibility standards, as well as increase your website traffic. In this post we’ll cover the top accessibility tools, so you can get started with improving your website for all users.
The 10 best accessibility testing tools

What Are Accessibility Testing Tools, Exactly?
Note: While accessibility tools can help detect common issues, some programs may return “false positives” for accessibility errors, which is why a human review of the tool’s findings is always recommended. Human user testing is an important next step in that process, as it sometimes reveals problems that the ADA testing tools can’t diagnose or that the reviewer missed.

Inaccessible websites raise a business’s risk of a civil lawsuit, so it’s good practice to review sites periodically for compliance with WCAG, Section 508, and other accessibility guidelines. Plus, making websites accessible benefits users of all abilities and demonstrates a business’s commitment to inclusiveness.
Remember that while accessibility testing tools may detect obvious errors, they may miss problems that human users and compliance experts would identify. Website accessibility reports offer a baseline analysis; human users and experts fill in the gaps and give you a complete picture of your website’s accessibility.
