When should we use accessibility overlays on our website?

Do not rely on an accessibility overlay to remedy underlying barriers or establish compliance; address accessibility in your website's structure and code. An overlay cannot replace accessible architecture, so build inclusion into design and development rather than treating it as a finishing task.

Correct underlying barriers rather than cover them

Accessibility overlays add a JavaScript widget or toolbar to a website, but they do not correct its underlying structure. Treating an overlay as an automatic fix can leave users facing barriers while giving website owners misplaced confidence about accessibility.

Build inclusion into the project from the beginning. Keep designers involved during development so they can check that their designs are executed properly and learn how technical choices affect the experience. For an existing website, focus improvements on the structure and code rather than relying on a layer added over inaccessible components. Retrofitting inclusion is harder when deadlines leave little time for changes.

In 2025, the Federal Trade Commission approved a final order requiring accessiBe to pay $1 million over misleading accessibility claims. The order bars unsupported claims that its automated products can make any website WCAG-compliant or maintain compliance over time.
