Social share preview (Open Graph)

Enter a page URL; see the share title, description and image in Facebook, LinkedIn, X and WhatsApp previews side by side.

Enter the full URL of the page you want to share.

Which tags are required?

If tags are missing, social networks pick random text and images from the page, and click-through rates drop. The check also tests whether the image is accessible.

  • og:title and og:description: the title and description of the share card
  • og:image: an image of at least 1200×630 pixels, under 5 MB
  • og:url and og:type: the page’s permanent URL and type
  • twitter:card: summary_large_image for a large image card on X

Frequently asked questions

I changed the image, but Facebook still shows the old one. Why?
Social networks cache previews. You can load the updated image by re-scraping the URL with Facebook Sharing Debugger and LinkedIn Post Inspector.
What is the best size for og:image?
1200×630 pixels (1.91:1) looks good on all major networks. Keep important text in the center of the image; some networks crop the edges.
Are X (Twitter) tags required?
No; if the Twitter tags are missing, X uses the Open Graph tags. Still, adding twitter:card set to summary_large_image is recommended for a large-image card.
