Checks
Open Graph title and description
Checks that pages declare both og:title and og:description, the two tags that control how a shared link's title and summary appear on social and chat platforms.
What this check looks for
This check looks for og:title and og:description meta tags with non-empty content. If both are present, it passes. If both are missing, it fails; if only one is missing, it warns, naming which tag is absent.
Why it matters
Open Graph tags control exactly what a link preview shows when your page is shared on Slack, iMessage, LinkedIn, Facebook, or pasted into a chat app — without them, these platforms fall back to guessing from the page's <title> and whatever text happens to be near the top of the body, which frequently produces a broken-looking or irrelevant preview. A weak or missing preview measurably reduces click-through on shared links, since a blank or generic-looking card doesn't earn the same trust as a clear, purposeful one. AI chat interfaces that render link previews when citing a source use the same Open Graph tags, so their absence produces the same degraded preview experience inside an AI answer as it does on social media.
How to fix it
Declare both tags with content tailored to how the page should look when shared:
<head>
<meta property="og:title" content="Wireless Noise-Cancelling Headphones | Acme Audio">
<meta property="og:description" content="40-hour battery, adaptive ANC, and free shipping on every order.">
</head>These can mirror your <title> and meta description, but writing them separately lets you tune the tone specifically for how the content reads in a shared-link card.
