Accessibility tree

The structured view of a page that screen readers and many browser agents use: its headings, links, buttons and form fields, with their names. If something isn't in it, many agents can't use it. See what an AI agent sees.

Why it matters

Many browser agents decide what to click by reading the accessibility tree, the same view screen readers use. A button or field that isn't properly described there is invisible to them, even though shoppers can see it perfectly well. Fixing it helps customers using assistive technology and agents at the same time, so the work pays twice.
