Rich result eligibility

WebSite Not eligible

Sitelinks search box

Missing: name

Detected schema types

WebSite json-ld → Sitelinks search box
1/2 required · 1/1 recommended
Required fields (Google)
  • name — Add the site name Required for the sitelinks search box
  • url — Required to anchor the search box to your domain
Recommended fields
  • potentialAction — Enables the in-SERP search box
Google's spec for this type

Your WebSite structured data is missing required fields for Google's Sitelinks search box. Without these, the page won't qualify for rich results.

Why this matters

Schema entity missing required properties — Google's rich-result eligibility check fails; the schema is in source but never renders enhanced.

Very low ratio suggests heavy framework overhead or boilerplate.
