Warning::
Missing required property "name" for WebSite
The "name" property is required for the WebSite schema type.
Warning::
Missing required property "url" for WebSite
The "url" 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.
Info::
Missing recommended property "potentialAction" for WebSite
Adding "potentialAction" 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.

Findings

  • Brand name differs across channels — users see inconsistent identity
  • No Organization schema — Google can't render your logo in the knowledge panel
  • No discoverable contact info — trust signal is weak, legal risk is higher in regulated regions
