document-title

Why we flag this

Screen reader users cannot identify the page.

Empty or generic <title> tag.

What the rule checks

Scope. Top-level HTML documents that have a title element.

Expectation. Fails when the document's title element is empty or contains only whitespace. A title set by script (document.title) before the audit reads the DOM is not empty. Without a title element the rule does not apply (document/title-missing reports that). One finding at the title element.

Source. WCAG 2.2 SC 2.4.2 Page Titled; ACT 2779a5 (HTML page has non-empty title); HTML §4.2.2

Detection: shared; needs dom.

Failing example

The check reports a violation here. Corpus case empty_title. The page may contain further findings for other rules.

        <h1>Page with an empty title element</h1>
        <p>The title tag above is present but empty.</p>
    </main>
</body>
</html>

Passing example

         missing for the moment of measurement, not necessarily for the page. -->
