JSON-LD entities have no @id

@id is a schema property that gives each entity, your organisation, a person, an article, a stable, unique web address acting as its canonical identifier. This check found none of your structured-data blocks declare an @id, so nothing on your site has this stable identifier attached. AI knowledge graphs (the systems that link mentions of the same real-world entity together across different pages and sites) use @id to recognise that a mention on one page and a mention on another refer to the same organisation or person. Without it, your entities are harder to de-duplicate and connect, weakening how confidently AI systems tie separate mentions of your business back to one identity. Your developer needs about 30 minutes. Add a canonical @id, for example https://yoursite.com/#organization, to your Organization, WebSite and Article JSON-LD blocks, and reuse that exact same @id consistently across every page rather than generating a new one per page. Consistency matters more than the exact format, so pick one pattern and apply it everywhere.
