Button without a name
Someone using a screen reader, or an AI agent, can't tell what each one does.
When we count it as met
When the same pages are measured again, no button appears without a name.
How to check it yourself
You can confirm it with the browser's accessibility inspector: the button shows no name.
Measure it on your site
UXMachine measures it in a real browser, on desktop and mobile, together with the other checks.
