Has og:title
Open Graph tags are the most widely-supported "structured representation of this page" mechanism. Even agents that don't speak any other format usually fall back to og:title for a clean human-readable name.
How the check decides
The check reads the content attribute of <meta property="og:title"> and asserts it is present and non-empty. Fails if the tag is missing or empty.
How to implement it
Add <meta property="og:title"> to every page’s <head>. Most frameworks expose this through their head/SEO component (Astro’s <SEO>, Next.js’s <Head>, Hugo’s partials/seo.html).
Pass
<meta property="og:title" content="Install a14y">
Fail
<!-- no og:title -->
