JSON-LD entity linking (sameAs)

sameAs ties your entity to ones an agent already knows, such as Wikipedia, Crunchbase, and your own profiles.

Category: Content accessibility
Standard: Recommended

What it checks

The extension reads the page’s JSON-LD, from the rendered page when it can and from the raw HTML otherwise. If there is Schema.org data, it looks for a sameAs property anywhere in it, including nested nodes and @graph entries.

Results

Status	When
Pass	The structured data declares `sameAs`
Warn	There is Schema.org data, but no `sameAs` anywhere in it
N/A	The page has no Schema.org JSON-LD

How to fix

Add sameAs to your Organization or Person entity, listing the URLs of the same entity elsewhere: your Wikipedia or Wikidata entry and your official profiles. That lets an agent resolve you to an entity it already knows.

<script type="application/ld+json">
  {
    "@context": "https://schema.org",
    "@type": "Organization",
    "name": "Example Ltd",
    "url": "https://example.com",
    "sameAs": [
      "https://www.wikidata.org/wiki/Q000000",
      "https://www.linkedin.com/company/example",
      "https://github.com/example"
    ]
  }
