What Wikidata does not show
A sameAs pointing at Wikidata is only corroboration if the Wikidata item points back; an unreciprocated link is a claim, not a confirmation.
Where Wikidata comes up on this site
- JSON-LD @id errors: what breaks and how to fix itA node with @id https://example.com/#organization can be referenced from every other page on the site, from a Wikidata entry and from another site's sameAs , and all of those references resolve to the same subject.
- Rich Results Test vs Schema Markup Validator vs CrawlCheckWhat does “sameAs links back” mean? sameAs lists the other places the same business appears: a Google Business Profile, a Facebook page, a Wikidata item, a directory listing.
