Open Graph & social preview

See exactly how a page will look when someone shares it on Facebook, LinkedIn or X. We read the Open Graph and Twitter Card tags, render the share card, and flag any important tags that are missing so your links never show up plain.

How it works

We fetch the page and read its og: and twitter: meta tags, plus the <title>, meta description, canonical link and favicon.
The cards mirror how Facebook, LinkedIn and X build a share preview. When an Open Graph tag is absent we fall back the same way they do (og:title to <title>, og:description to the meta description).
X shows a big-image card only when twitter:card is summary_large_image; otherwise it uses a small summary card, which we render too.
Missing important tags are flagged with a short note on what they affect, so you know what to add.

After you fix your tags, re-run the tool to confirm the card looks right, then monitor the page with SiteGauge so you get alerted if the share card ever changes.
