Automated tools like Accessibird catch a huge number of issues, but they cannot fully replace feedback from real users. To make your site genuinely accessible, you should also test it with people who use assistive technology every day.
Set up real user sessions
Work with users who have disabilities and ask them to perform real tasks on your website while the widget is active. Observe where they get stuck and listen carefully to the friction points they describe.
Feed insights back into your config
Use that feedback to fine-tune the widget configuration, prioritize remediation tasks and validate the fixes you've already shipped. Combining automated scans with human testing gives you a far more honest view of how your site really performs.
