Open Graph Checker

What is Open Graph? It is the meta-tag protocol (created by Facebook, now universal) that controls how a link unfurls when shared: og:title sets the headline, og:description the text, og:image the preview picture, and og:url the canonical share address. Facebook, WhatsApp, LinkedIn, Slack, Discord and iMessage all read these tags to build link previews.

An Open Graph checker fetches a URL and shows which OG tags it serves — and therefore what the share card will look like — before you or anyone else posts the link. No tags means the platform guesses, often ugly: a random page image and truncated text, or a blank card.

Enter a URL, click Check, and see the page's Open Graph tags as platforms read them: title, description, image, type and URL — with the gaps flagged.

The checks that save embarrassment: og:image present, absolute (full https URL, not a relative path — the classic reason images don't show) and correctly sized — 1200 × 630 px is the standard that renders sharply everywhere; og:title distinct and compelling (it can differ from your SEO title); and og:url pointing at the canonical page. Run it before campaigns, after site changes, and whenever a shared link renders blank — platforms cache previews, so a page that had broken tags at first share keeps the broken card until the cache is refreshed with Facebook's Sharing Debugger or LinkedIn's Post Inspector.

The companion Open Graph Generator builds the tags; this checker verifies the live page serves them.
