Open Graph Checker

Facebook created the protocol, but LinkedIn, WhatsApp, Slack, Discord, Telegram, iMessage, and Pinterest all read og: tags to build their link previews. X reads its own twitter: tags first and falls back to Open Graph for anything missing. In practice, one good set of og: tags covers almost every place a link gets pasted.

1200 × 630 pixels is the safe universal size: it renders as a full-width card on Facebook, LinkedIn, and X, and scales down cleanly everywhere else. Keep it under about 1 MB — some platforms silently skip images that are too large — and use an absolute https:// URL, not a relative path.

Every platform caches the first version of a link it ever sees, sometimes for weeks. This tool always reads the live page, so if it shows the new values, your tags are correct. To force Facebook to refresh, paste the URL into its Sharing Debugger and click 'Scrape Again'; LinkedIn has a similar Post Inspector.

Not directly — Google doesn't use og: tags as a ranking signal. What they change is how often a shared link gets clicked, and links that get clicked and shared more tend to earn the traffic and mentions that do influence rankings over time. Think of them as conversion tags for shares, not ranking tags.

The canonical tag tells search engines which URL is the 'real' one for indexing. og:url tells social platforms which URL to count likes and shares against. They should almost always be the same URL — if they disagree, share counts get split across variants.
