Knowledge Graphs are structured databases that map out real-world entities (people, places, concepts) and encode the relationships between them in graph form. Search engines and AI platforms leverage Knowledge Graphs to enrich search results, surface fact boxes, and power entity-based queries. For AI SEO, integrating content with major Knowledge Graphs (e.g., Google Knowledge Graph, Bing Entity Search) and ensuring that your entities are connected to broader graph networks can boost “authority” signals and improve AI discovery.
