A database of entities (people, places, organizations, concepts) and their relationships, used by search engines and AI systems to understand meaning beyond keywords. Knowledge graphs connect the dots — they know that “Apple” can mean a fruit or a company, and which interpretation is correct based on context. For SEO, this means optimizing for entity recognition: making it clear who you are (your brand), what you do (your services), and how you relate to broader topics. Appearing in knowledge graphs increases visibility to both traditional search and AI systems. See how knowledge graphs work and knowledge graph optimization.
