Why Open Graph Tags Matter

When someone shares a link on Facebook, LinkedIn, WhatsApp, Slack or X, the platform reads the page's Open Graph and Twitter Card tags to build the preview: the title, description and image. Without them, platforms guess, and the preview is often a random image or nothing at all.

Enter a web address and the debugger fetches the page, lists every tag it finds, flags missing ones and shows how the preview is likely to look.

The tags every page should have

  • og:title and og:description: the headline and summary in the preview.
  • og:image: a full https:// address to an image of 1200 by 630 pixels. A relative path like /images/card.png won't work on most platforms.
  • og:url: the canonical address of the page.
  • twitter:card: set to summary_large_image for a big image preview.

Social platforms cache previews. After fixing tags, use each platform's own sharing debugger to force a refresh.

Frequently asked questions

What size should an Open Graph image be?

1200 by 630 pixels is the standard. Keep important text away from the edges, as some platforms crop to a square.

Why is my link preview still showing the old image?

Platforms cache previews, sometimes for days. Use Facebook's Sharing Debugger or LinkedIn's Post Inspector to ask them to fetch the page again.

Do I need Twitter Card tags as well as Open Graph?

X falls back to Open Graph tags for most fields, but it needs twitter:card to know which preview layout to use.
