// Entity Check

Does your brand resolve to a real entity?

Enter a brand or a domain. We check whether it exists as a resolvable entity in Wikidata and Google's Knowledge Graph. For a domain we also check, whether your own schema actually links to it.

Syntax isn't the same as resolution

Every schema validator on the internet checks whether your markup is well-formed. None check the thing that actually matters: does that markup resolve to an entity that exists in the knowledge bases AI models lean on? A perfectly valid Organization block that points at nothing is a brand AI can't describe with confidence. This tool checks the resolution, not the syntax.
