Open Graph Tags Checker

Open Graph tags are <meta property="og:…"> tags that control how a link looks when it is shared on Facebook, LinkedIn, WhatsApp, Slack, Discord and many other apps: the title, description, image and canonical URL. Without them, each platform guesses, often picking the wrong image or none at all. They do not affect Google rankings.

1. Enter the URL you plan to share.
2. The tool reads og:title, og:description, og:image, og:url and og:type from the page.
3. Add any missing tags and make sure og:image is a full https:// URL.

Passed

All five core tags are present and og:image is an absolute URL.

Needs attention

One or more core tags are missing, or og:image is a relative path that most platforms cannot load.

The Open Graph protocol requires og:title, og:type, og:image and og:url. Add og:description too. Use an image of at least 1200 × 630 pixels, which is the size Facebook and LinkedIn recommend for large previews.

<meta property="og:title" content="Free robots.txt checker">
<meta property="og:description" content="See if Googlebot can crawl your page.">
<meta property="og:image" content="https://www.example.com/og/robots.png">
<meta property="og:url" content="https://www.example.com/tools/robots-txt-checker">
<meta property="og:type" content="website">

export const metadata = {
  openGraph: {
    title: 'Free robots.txt checker',
    description: 'See if Googlebot can crawl your page.',
    url: 'https://www.example.com/tools/robots-txt-checker',
    images: [{ url: 'https://www.example.com/og/robots.png', width: 1200, height: 630 }],
    type: 'website',
  },
};

Platforms cache previews. Use Facebook’s Sharing Debugger or LinkedIn’s Post Inspector to fetch the page again.

• Open Graph tags for sharing

  Checks for the core Open Graph tags: og:title, og:description, og:image, og:url, og:type.

  Why it matters: Open Graph tags control how the page looks when shared on Facebook, LinkedIn, Slack and many other platforms. Missing tags produce a poor or empty preview.

  If it fails: Add og:title, og:description, og:image (absolute URL, ≥1200×630), og:url and og:type to <head>.

• Open Graph image is an absolute URL

  Checks og:image is set and is an absolute URL (required by most platforms).

  Why it matters: Facebook, LinkedIn and others require an absolute og:image URL. A relative path produces a broken or missing preview image.

  If it fails: Set og:image to a full absolute https:// URL of an image at least 1200×630.
