## Definition

Brand architecture is the structured relationship between a company's master brand, sub-brands, product lines, and service offerings — defining how they relate to each other, how they share or differentiate equity, and how they are presented to different audiences.

## Why It Matters for AI Search

Brand architecture has direct implications for entity SEO. A company with multiple sub-brands, product lines, or service categories needs to decide whether to build entity authority around the master brand, the sub-brands, or both — and how to structure schema markup, internal linking, and third-party citations to reflect that architecture. Confused or inconsistent brand architecture produces confused entity graphs and inconsistent AI representations across the brand family.
