Structural accessibility basics: What It Means and How to Fix It

Structural HTML checks found missing accessible names, image alternatives, document language or skipped heading levels.

Do this: Fix missing names, alternatives, language and heading structure. Assistive technology cannot reliably operate controls or understand content without these semantics.

The fix, in one snippet

Illustrative values. Change the paths, hostnames and options to match your own site before using it.

The sections below explain what is tested, why it matters and the alternatives.

What we test

Scan.now performs deterministic HTML checks for document language, image alt attributes, programmatic form-control and button names, and heading order. This is a useful baseline, not a WCAG conformance claim.

Why it matters

These semantics are how screen readers and other assistive technology identify content and controls.

How to fix it

Use native elements, associate every control with a visible label, provide meaningful alternatives, declare the document language and keep headings hierarchical.

Where this fits

Structural accessibility basics is check 10 of 19 that the website accessibility scanner runs under page content and javascript, ordered the way they are worth fixing. That ordering is the point: Fixing this one while the check above it still fails buys less than it looks like.

Fix this one first

Above it in the same category sits POST form without recognisable CSRF protection (medium), where a POST form has no recognisable anti-CSRF field. An attacker who has that does not need this, so it is the better use of the same hour.

What fixing this still leaves open

Structural accessibility basics closes one route in. Immediately below it: Web performance baseline, where the initial response is slow, oversized or contains many parser-blocking scripts; Advertising and tracking endpoints, where which of the page's third-party hosts exist to advertise to the visitor or to follow them, matched against the EasyList and EasyPrivacy blocklists that also power our <a href="/ad-blocker">ad blocker</a>; CMS / generator version disclosure, where the page announces the CMS or static-site generator it was built with, usually including the version, in a meta tag, header or comment banner.

Found in the same scan

The website accessibility scanner reports this alongside checks from other categories that are at least as serious, including Path traversal / local file inclusion, where a path-like parameter returned a known local operating-system file signature, and Session token exposed in URL, where a session-like token name appears in a discovered URL. A single run of website accessibility scanner answers all of them at once.
