Web Accessibility Overlays Do Not Work

Smart business decisions tend to be equated with cutting costs and saving money.

Over the past decade or so, “Better! Faster! Cheaper!” has become the rallying cry for business process reengineering and new initiatives within every sector. As a developer and former business owner, I get this.

Efficiency is essential.

I tend to look favorably on the fastest, most streamlined solution, and as such, I have a lot of empathy for clients who are seeking fast fixes to ensure that their website and all of their digital assets comply with WCAG 2.1 for ADA accessibility.

But as a developer, my focus is, first and foremost, on solving problems, and I can state unequivocally that overlays can't be counted on to solve the challenges associated with digital accessibility.

A recent web accessibility legal case, Haynes vs. Hooters set the precedent that organizations are required to remediate their actual code and not rely on band-aid dashboards or overlay solutions that appear to represent a quick fix that requires seemingly little hands-on maintenance.


What are accessibility overlays?

Accessibility overlays are automated software such as scripts, tools, and widgets that claim to improve the accessibility of web content for people with disabilities.

Some examples are accessiBe,, and AudioEye.


Do accessibility overlays work?

Short answer is no, overlays do not work. They do not fix your accessibility issues and in fact, can open you up to an ADA lawsuit.

Here are 4 key challenges inherent to overlays:


1. Visually impaired users don't typically use them.

They tend to have their own tools with their own voice and reader settings with which they are comfortable and proficient based on their experience and ability level.

Your goal is to make your code available to whatever tools and devices they prefer using, not force them to use your overlay tool that has pre-selected settings and options.


2. Visually impaired users typically have their own stylesheets and ways to access the web.

They don’t tend to use presets from widgets because widgets complicate the experience for them and the inability to disable or override them can be frustrating.


3. Accessibility overlays simply don't work well with mobile devices.

Unless a significant expenditure is invested in customizing them to the individual site, you can't expect overlays to work with your mobile site.

Accessibility overlays do not actually fix the underlying accessibility issues. Imagine you have a pizza with sauce that has gone bad, but you put a lot of cheese on it to cover up the sauce. That's what you do when you use an accessibility overlay.


4. Accessibility overlays basically amount to putting a line of JavaScript code that pulls preloaded information onto your site.

So even if the overlay has been customized as part of your package, to make it fully compliant it's nearly impossible to keep it that way, because accessibility issues can re-emerge with any subsequent change to your site.
