Knowledge graph optimization
Google's Knowledge Graph is a database of billions of entities and their relationships.[1] When your practice is properly represented in the Knowledge Graph, you become more visible in search results, AI overviews, and knowledge panels.
What is the Knowledge Graph?
The Knowledge Graph is Google's way of understanding the world. It contains information about people, places, businesses, and concepts – and how they relate to each other.[1]
When you search for a well-known entity, the information box that appears (the knowledge panel) is pulled from the Knowledge Graph.[2]
For healthcare, the Knowledge Graph contains information about medical conditions, treatments, medications, and healthcare providers.
How to get into the Knowledge Graph
Google Business Profile: Claiming and optimizing your GBP is the most direct path to Knowledge Graph inclusion for local businesses.[2]
Wikipedia and Wikidata: Having a Wikipedia page or Wikidata entry significantly increases Knowledge Graph presence. These are editorial, so notability is required.
Structured data: Schema markup helps Google understand your entity and its attributes.[3]
Consistency: The same NAP information across all platforms reinforces your entity identity.
Knowledge Graph optimization for practices
Claim all relevant profiles: Google Business, Healthgrades, Vitals, WebMD, Zocdoc, and specialty-specific directories.
Use consistent naming: "Dr. John Smith, MD" everywhere, not variations.
Build entity relationships: Link your providers to your practice, your practice to conditions you treat, and your services to the outcomes you deliver.
Earn mentions: Being mentioned on authoritative healthcare sites strengthens your entity presence.
Key takeaways
- The Knowledge Graph is Google's database of entities and relationships

Medical schema markup
Schema markup is a structured data vocabulary that helps search engines understand your content beyond the words on the page. For healthcare practices, medical schema types communicate your services, provider credentials, treatment details, and clinical expertise in a format that both search engines and AI systems can reliably parse and cite.
