Open Graph Checker — OG and Twitter Card tags online

This tool checks Open Graph and Twitter Card meta tags for any page and shows how it will appear when shared on social networks: Facebook, Twitter/X, LinkedIn, Telegram.

What is Open Graph

The Open Graph Protocol (OGP) is a standard for <meta property="og:..."> tags, originally developed by Facebook. It lets a website control how a page looks when a link is posted on social platforms: image, title, and description.

Core OG tags

• og:title — page title (up to 60 characters);
• og:description — short description (up to 160 characters);
• og:image — preview image URL (recommended 1200×630 px);
• og:url — canonical URL of the page;
• og:type — object type: website, article, video, etc.;
• og:site_name — name of the site.

Twitter Card

Twitter uses its own <meta name="twitter:..."> tags. If they are absent, Twitter falls back to OG tags. Main card types: summary, summary_large_image, app.
