Free Social Card Grader
Enter any website and get a plain-English share-card score — 12 automated checks of the Open Graph and Twitter/X markup that decides whether your links unfurl into a clickable card or die as bare URLs.
Privacy: we fetch the URL you enter to run the checks, but we never store it. The only thing recorded is an anonymous "grader run" for our own stats. Public websites only.
What the grader checks
Does the card read well?
An og:title that survives truncation, an og:description sized to display fully, and no empty or duplicated tags confusing the validators.
Does the card have a picture?
An absolute og:image URL every bot can fetch, 1200×630 size hints so the card renders full-bleed, and og:image:alt for accessibility.
Does every platform render it?
A twitter:card tag for X, and the og:url + og:type + og:site_name identity trio so the card knows what it is and where it belongs.
