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.
