Entity Health measures the health and completeness of a brand's entity on Wikidata and Knowledge Graphs — the sources LLMs use as ground truth. A complete and up-to-date entity improves the AI's ability to correctly recognize and cite the brand.
What is Entity Health?
Entity Health evaluates the health and completeness of a brand's digital entity in structured knowledge bases, primarily Wikidata and Google's Knowledge Graphs.
These knowledge bases serve as "ground truth" for AI models. When an LLM needs to verify brand information, it relies primarily on these structured sources.
Why Entity Health is Critical for GEO
A well-defined entity in Wikidata offers several GEO visibility advantages:
- Recognition: AI identifies your brand as a known entity, not just a word
- Accuracy: structured information reduces hallucination risks
- Connections: links between entities (founder, sector, location) enrich context
- Multilingual: Wikidata is natively multilingual, benefiting international visibility
Evaluation Criteria
Wikidata Completeness
- Does the Wikidata entity exist?
- Properties filled: description, website, sector, founding date, founder
- Labels and descriptions in multiple languages
- External identifiers
Google Knowledge Graph
- Knowledge Graph presence
- Information richness
- Consistency with Wikidata data
Improving Entity Health
- Create or complete your brand's Wikidata entity
- Add descriptions in French, English, Spanish and German
- Link the entity to other relevant entities
- Keep information up to date
