## Definition

Brand hierarchy is the structured relationship between a company's brand tiers — master brand, endorsed brands, sub-brands, and product brands — defining the visual and verbal rules for how each tier is expressed and how they relate to each other in communication and identity systems.

## Why It Matters for AI Search

Brand hierarchy has direct implications for entity SEO strategy. Each brand tier needs its own entity infrastructure — schema markup, Wikidata entry, sameAs links — to be properly recognized and distinguished by AI systems. A company with multiple sub-brands that shares one undifferentiated entity record risks having all brand activity attributed to a single muddled entity. Clear brand hierarchy, reflected in consistent schema implementation at each tier, enables AI systems to represent each brand element accurately and independently.
