Brand Presence

Partial brand coverage — a few channels are missing brand signals.

Findings

  • Missing brand name in: og:site_name, twitter:site, Organization.name
  • Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
  • Organization schema missing logo — add a logo property pointing to a square PNG
  • Organization schema missing url — point it at the canonical homepage
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • No discoverable contact info — trust signal is weak, legal risk is higher in regulated regions

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

Missing og:site_name
The og:site_name tag displays the website name in social previews.

The og:site_name tag displays the website name in social previews.

Why this matters

Without og:site_name, social cards omit the brand attribution — users see the post but not who published it.

og:site_name appears in the social card chrome (above the title in Facebook/LinkedIn previews). Without it, posts read as anonymous URLs. Set it to your brand name to get free attribution on every share.

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

Missing recommended property "logo" for Organization
Adding "logo" can improve how search engines display your content.

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

The "name" property is required for the Organization 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 "url" 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.
