Knowledge Graph

AI engines build their own internal knowledge graphs by extracting entities from training data. Your brand exists as an entity if and only if AI systems have ingested enough authoritative signals about it: Wikipedia/Wikidata, schema markup, consistent NAP across the web, and links from trusted sources.

Brands without a strong knowledge graph footprint get omitted from AI answers no matter how much SEO they do. Knowledge graph completeness is one of the four pillars of AEO.
