Not scattered markup blocks, but one connected graph where company, people, services and content are linked and verifiable. ## Become an entity, not just a website ### Schema markup & structured data – from loose tags to knowledge graph Most websites carry schema markup as scattered fragments – an Organization here, a Product there, with nothing connecting them. We build it differently: a unified graph with @id references, where every page points into the same network of entities. Organisation, brand, people, services and cases are interlinked, and key concepts are anchored in Wikidata, so machines know exactly who and what you are. The proof is this website. Every single page is part of one validated graph – WebSite, Organization, Person, OfferCatalog, ItemList, breadcrumbs and image licences – with zero errors in Google's and Schema.org's validators. Even this service description appears as an entity in the very OfferCatalog it describes. ## One graph, not loose blocks The payoff is concrete: rich results in search, an unambiguous identity in Google's knowledge graph, and source material language models can cite correctly. Structured data is the foundation beneath both SEO and GEO – ranking and AI answers both depend on the machine understanding your site without guessing. **What we deliver:** Schema audit & validation · JSON-LD knowledge graph · Entity anchoring in Wikidata · OfferCatalog & Service markup · Rich results optimisation · Breadcrumbs, images & licences ## For companies that want to be understood by machines Search engines and language models reward sites they can read without doubt. A precise entity graph is the difference between being guessed at and being cited. How connected is your structured data? [Let's look at your graph](https://www.blackbook.dk/contact/).
