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

  • Missing brand name in: og:site_name, twitter:site, Organization.name
  • 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
  • No Organization schema — Google can't render your logo in the knowledge panel
  • 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.

Warning::
Missing required property "name" for WebSite
The "name" property is required for the WebSite schema type.
Info::
Missing recommended property "description" for WebSite
Adding "description" can improve how search engines display your content.

The "name" property is required for the WebSite schema type.

Why this matters

Schema markup missing required properties is silently rejected by Google — your structured data appears in source but never as a rich result.

Learn more

Each schema.org type has required properties (Article needs headline + author + datePublished; Product needs name + offers; etc.). Missing them means Google's rich-result eligibility check fails. The Search Console Rich Results Test surfaces specific gaps. Fix the missing property; rich results re-appear within hours.

Adding "description" can improve how search engines display your content.

Why this matters

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

Learn more

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.
