Test manually
Scanners miss most real barriers.
An automated scanner can pass a site that nobody can actually use with a keyboard.
Automated accessibility tools are useful and badly oversold. They reliably find missing alternative text and poor contrast, and they cannot evaluate whether a form can be completed without a mouse, whether focus is trapped in a modal, or whether a screen reader announces anything meaningful when a page updates. Those are the barriers that actually stop people, and they are found by a person testing with the same tools disabled users rely on.
Overlay widgets deserve particular scepticism. Sold as instant compliance, they layer controls over an inaccessible site rather than fixing it, and disabled users have been consistently clear that they often make matters worse. They have appeared in legal claims rather than preventing them.
And an accessibility statement should be honest. Public sector bodies must publish one, and a statement claiming full compliance on a site with known failures is a worse position than one that lists the failures with a plan and a date. Accuracy is the requirement; perfection is not.

Not behind an overlay widget.
Accuracy beats a compliance claim.
