FIX
No Open Graph tags found — social sharing previews will be generic.
Warning::
No Open Graph meta tags found
Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared.

Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared.

Why this matters

Without Open Graph tags, social shares show a broken or empty preview card.

Learn more ▾

When someone shares your URL on Facebook, LinkedIn, Slack, iMessage, or any modern chat app, the preview comes from <meta property="og:*"> tags. Without them you get either no card or whatever fragment the social platform guesses — usually unflattering. The four core og: tags (title, description, image, url) cover what every major platform actually reads.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • No social share image — shared links render as bare URLs
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • og:title missing
  • og:image missing
  • twitter:card missing
  • Only partial contact info discoverable — consider adding a dedicated contact page or mailto/tel link

How consistently your brand appears across channels — shared link previews, structured data, favicon, contact info.
