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
  • No favicon link tags detected — browsers fall back to the generic globe
  • og:title missing
  • og:image missing
  • twitter:card missing
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • 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.

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.
