Semantic Architecture

Every page on the site participates in a shared @graph via consistent schema @id URIs:

  • https://probuildhomeservices.com/#business — the Organization (referenced by every page as publisher)
  • https://probuildhomeservices.com/#founder — Kevin Sullivan, the Person (referenced as author/founder)
  • https://probuildhomeservices.com/#website — the WebSite (isPartOf on every page)
  • https://probuildhomeservices.com/programs/mass-save/#entity, etc. — each entity hub anchors its own ID

This @id continuity is what builds the Knowledge Graph signal: search engines crawl multiple pages, recognize the consistent entity references, and assemble a unified entity profile in the Google Knowledge Graph and equivalents in Bing, Yandex, and AI Search engines.
