The Risk of Overlay Accessibility Tools: Why True Compliance Matters
As the EAA deadline approaches, many businesses are scrambling for fast fixes. Some accessibility tools have been marketed as a simple, one-click solution to achieve compliance. However, these web accessibility testing tools often create more problems than they solve. In reality, true compliance requires a much deeper and more effective approach.
What Are Overlay Accessibility Tools?
Overlay accessibility tools are software plugins or scripts that attempt to retrofit accessibility features onto a website. They often include elements like text resizing, colour contrast adjustments, and screen reader toggles. These tools are marketed as instant fixes, but they do not address the actual code or structure of a website.
The danger is that many business owners are misled into thinking their site is compliant when it is not. The EAA does not recognise overlays as a valid path to compliance. Relying on them can leave you vulnerable to complaints, legal action, and reputational damage.
Why Accessibility Tools Fall Short
The core issue is that overlays sit on top of existing content without fixing the underlying problems. A screen reader user, for example, will still encounter unlabelled buttons, missing alt text, keyboard traps, and inaccessible forms. These are structural issues that overlays cannot repair.
Compliance means getting things right at the foundation. If a form is not labelled correctly, or a menu cannot be navigated with a keyboard, no overlay will fix that. These are things that have to be coded correctly and tested properly. Relying on surface-level accessibility tools only gives a false sense of security.
In many cases, overlays actually interfere with assistive technology. There have been numerous complaints from disabled users who found these tools actively made the website harder to use. So not only are they ineffective, they can make things worse.
How Web Accessibility Testing Tools Support Real Compliance
Achieving compliance involves a structured approach:
- Web audit: A comprehensive review of your website against WCAG guidelines
- User testing: Involving disabled testers to explore real-world usability barriers
- Fixing the code: Addressing issues like poor heading structure, ARIA misuse, contrast failures, and inaccessible navigation
- Accessibility statement: Publishing a legally valid statement that outlines known issues and your roadmap to full compliance
This process takes time and expertise, but it leads to genuine improvements. Not just for legal compliance, but for all your users. A properly coded website loads faster, performs better in search results, and provides a smoother experience for everyone.
The Consequences of Relying on Overlays
Some companies have learned this lesson the hard way. There have been multiple cases where organisations using overlays were still sued under accessibility legislation. When real users could not access the content, the existence of an overlay was not accepted as a defence.
Legal frameworks around the world, including the EAA and the Americans with Disabilities Act, are increasingly focused on real-world usability. If your website cannot be used by a blind person with a screen reader, or a motor-impaired user navigating by keyboard, you are at risk. Accessibility tools alone will not protect you from that liability.
In fact, using the wrong web accessibility testing tools may be worse than doing nothing. It shows you are aware of accessibility but have chosen a non-compliant solution. That increases your exposure rather than reducing it.
What Real Web Accessibility Testing Tools Reveal
We often hear from businesses who have installed overlays, received poor results, and now want to do things properly. The good news is that it is never too late to start. We work with companies of all sizes to rebuild trust and create websites that work for everyone.
Our approach is based on lived experience. Our testers include screen reader users, people with cognitive impairments, and others who rely on accessible websites every day. When they test your site, they are not looking at it through a checklist. They are using it as a real person would — and that is where true compliance begins.
We then follow up with a technical audit, detailed recommendations, and support throughout the process. We also create a compliant accessibility statement that outlines your progress, making it clear to regulators that you are taking the right steps.
Start With an Honest Assessment
If you are not sure whether your site is compliant, we are happy to help. We can run a quick scan and tell you honestly where you stand. From there, we can guide you towards full compliance without relying on accessibility tools that do not deliver.
The deadline for the EAA is almost here. There is still time to act — but only if you take the right steps now.
