Helps you optimize for Google's entity understanding system rather than just keyword matching. You'd reach for this when setting up Organization or Person schema, strengthening brand identity across platforms, or preparing content for AI citation in tools like Perplexity and Copilot. The guide is thorough on the why (entities power Knowledge Graphs, BERT, AI overviews) and the how (schema placement, entity signals, consistent naming). Useful detail: it's specific about where Organization schema should live (root layout, not just the About page) and includes @id patterns for entity linking. The entity versus keyword framing is clear enough that you could hand this to a content team.
