Open Graph Tags
Checks for og:title, og:description, og:image, and og:url in the <head>.
What this check measures
We parse all `<meta property="og:*">` tags and verify the four core Open Graph fields are set with non-empty values. og:image is checked for valid URL and recommended 1200×630 dimensions.
Why it matters
OG tags control link previews on Slack, WhatsApp, LinkedIn, Discord, Telegram, Facebook, and iMessage. Missing tags = no preview card = scrolled past. A well-designed OG image lifts link CTR on social by 30-80%.
How our audit detects it
Parse meta tags with property starting `og:`. Check for og:title, og:description, og:image, og:url, og:type. Fetch og:image URL to verify accessibility.
Typical findings
- error_outlineNo Open Graph tags at all — link previews fall back to bare URLs.
- error_outlineog:image URL is relative — some scrapers require absolute URLs.
- error_outlineog:image is 400×400 (square) — LinkedIn and Slack crop it.
- error_outlineSame og:image on every page including blog posts.
How to fix
Add og:title, og:description, og:image (1200×630 absolute URL), og:url, and og:type to every page. Mirror values into twitter:* for X. In Next.js, use the metadata.openGraph field per page.
