Social share preview checker

Paste a link to see exactly how it will look when shared on X, LinkedIn, Facebook, and iMessage, and what Open Graph tags are missing.

Why this matters

When someone shares your link, the social network doesn't read your page; it reads a handful of Open Graph and Twitter card tags in your HTML head. Get them wrong and your link shows up as a bare URL with no image, which almost nobody clicks. Get them right and every share becomes a small ad for your page.

This checker fetches your page, reads those tags, shows you the card each network will build, and flags what's missing: the image, the title, the description, or the card type.

The tags that matter

  • og:title and og:description, the headline and snippet of the card
  • og:image, the preview image (use 1200×630 for a crisp large card)
  • twitter:card, set to summary_large_image for a full-width image on X
  • og:url, your canonical URL, so shares dedupe correctly

Frequently asked questions

What is an Open Graph tag?

Open Graph (og:) tags are bits of HTML in your page's head that tell social networks the title, description, and image to show when someone shares your link. Without them, the network guesses, usually badly.

Why isn't my image showing when I share my link?

Most often there's no og:image tag, the image URL is broken or blocked, or the file is too large. This checker shows which of those it is.

What size should my og:image be?

1200×630 pixels is the safe size for a large card across X, LinkedIn, and Facebook. Keep it under about 5MB and at least 600px wide.

Does this work for any website?

Yes, paste any public page on the web. The checker reads the page's tags the same way a social network would.

How do I add these tags to my own site?

Add og: and twitter: meta tags to your page's head. Every site built with One Minute Page includes them automatically, filled in from your content.
