What is Open Graph & how it works

How platforms build the preview card for your link

Open Graph is a set of <meta property="og:…"> tags that tell Facebook, LinkedIn, Slack and other apps what to show when someone shares your link: the title, description, image and URL. X (Twitter) reads its own twitter: tags and falls back to Open Graph.

When the tags are missing, platforms guess from the page and often pick the wrong image or text. This tool fetches the page like a link-preview crawler, extracts the Open Graph, Twitter Card and core SEO tags, previews how the share card will look, and scores how complete the markup is.

og:title / og:description
The headline and summary shown on the share card.
og:image
An absolute URL to the preview image; 1200×630 px suits most platforms.
twitter:card
Card layout on X, e.g. summary_large_image for a full-width image.

Frequently asked questions

Common questions about Open Graph and social previews
5 Q&A

The core four are og:title, og:type, og:image and og:url. Add og:description too; most platforms show it under the title.

1200×630 pixels (a 1.91:1 ratio) works well on Facebook, LinkedIn and X large cards. Use an absolute HTTPS URL and keep the file under a few megabytes.

Platforms cache previews. Use the Facebook Sharing Debugger or LinkedIn Post Inspector to force a re-scrape; other apps refresh on their own schedule.

X falls back to Open Graph for the title, description and image, but it needs twitter:card to choose the layout. Add <meta name="twitter:card" content="summary_large_image"> for a large image card.

Not directly as a ranking factor, but better share cards earn more clicks and shares. The standard title, description and canonical tags checked here do matter for search.
