What are Open Graph and Twitter Cards?

Open Graph (og:) and Twitter Card (twitter:) are meta tags that define how a URL looks when shared on social platforms (Facebook, LinkedIn, X/Twitter, etc.). They control the title, description, image, and sometimes type (e.g. article, product) that appear in the preview.

Why they matter

• Click-through — A clear title, description, and image make shares more appealing and can improve traffic from social.
• Branding — Consistent previews make your content recognisable and professional.
• Fallback — If you don’t set them, platforms will guess from your page (often poorly).

Common tags

• og:title / twitter:title — Headline for the preview.
• og:description / twitter:description — Short summary.
• og:image / twitter:image — Image URL (often 1200×630 or similar for best display).
• og:url — Canonical URL of the page.
• twitter:card — e.g. summary_large_image for a big image preview.

Common issues

• Missing — No og or Twitter tags, so platforms scrape default or weak content.
• Wrong image size or broken URL — Image not found or too small, so preview looks bad or falls back.
• Mismatch with page — Preview says one thing, page shows another; can hurt trust.

How BearAudit checks them

BearAudit validates Open Graph and Twitter Card tags on each crawled page. We report missing or invalid values (e.g. missing image, bad URL) so you can fix social previews and improve how your content looks when shared.
