What is Open Graph?
Open Graph is a set of meta tags, originally created by Facebook, that controls how a web page appears when it's shared on social media. It lets you specify a title, description, image and other details instead of leaving it to the platform to guess.
How do I use this tool?
Enter a URL above and click 'Check tags'. The tool fetches the page, reads its Open Graph and Twitter Card meta tags, and shows you a preview of how the page will look when shared, along with a checklist of which tags are present.
Which Open Graph tags matter most?
og:title, og:description and og:image are the tags most platforms rely on to build a preview card. og:url, og:type and og:site_name add extra context but aren't always shown.
What's the difference between Open Graph and Twitter Cards?
Twitter Cards (twitter:* tags) are X/Twitter's own meta tag standard. Most platforms fall back to Open Graph tags if Twitter-specific ones aren't present, but setting both gives you the most control.
Why is my og:image not showing up?
The image URL must be absolute (starting with https://), publicly accessible, and reasonably sized – most platforms want at least 200×200px, with 1200×630px recommended for a full-width card.
What about the rest of the page's SEO tags?
Open Graph only covers how a page looks when it's shared. For title tags, meta descriptions, canonical URLs and everything else search engines care about, run the same URL through the meta tag checker.
