Glossary · Finding the way: navigability
Accessible name
The name a button, link or field has in the accessibility tree, from its text, label or aria-label. An icon-only button with no name is invisible to agents.
Why it matters
Unnamed buttons are the most common problem we find: in our study of 255 online stores, 58% had buttons or links with no name an agent can read, most often icon-only cart, search and menu buttons. An agent can't press what it can't identify. Naming them is usually quick work for a web developer, and it helps screen reader users too.
