## Summary

AI search engines operate on a "comprehension budget" - structured entity data (Schema.org/JSON-LD) reduces GPU inference costs, making your brand cheaper to cite and therefore more likely to appear in AI-generated answers. The shift from page-based SEO to entity-based authority requires deeply nested schema markup, external disambiguation via sameAs links, and schema actions that make your brand "callable" by AI agents.

## Key Insight

The core economic argument is compelling: AI models spend real compute resolving ambiguous or unstructured data. If your brand forces expensive inference, the model defaults to hallucination, a competitor, or ignores you entirely. Providing a "comprehension subsidy" through structured markup shifts the cost from deep inference to fast knowledge graph lookups.

Key non-obvious takeaways:

- **300% improvement** in LLM response accuracy when enterprise content knowledge graphs provide factual grounding. **20-40% traffic lift** from deeply nested, error-free advanced schema.
- **Entity drift** is a silent killer: when your human-visible content (prices, hours, stock) changes but schema stays static, AI lowers your confidence score to zero citations.
- **Schema actions** (BuyAction, ReserveAction, ScheduleAction) are what separate "discoverable" brands from "transactable" ones in the agentic web. Without them, AI agents mention you but can't complete transactions - so they bypass you.
- The **minimum viable entity graph** for any site is three pages: Home (Organization schema), About (AboutPage linked via @id), Contact (ContactPage with ContactPoint). This triangle of trust is the starting point.
- **sameAs property** linking to Wikipedia, Wikidata, LinkedIn, and Google Knowledge Graph acts as authority transfer - it "collapses" identity ambiguity before inference even starts.
- New KPI: **Share of Model (SOM)** - percentage of time your brand appears in generative responses for category queries. This replaces share of voice.
- Stop using generic schema types like "Article" - use specific types (TechArticle, MedicalWebPage, FinancialService). Schema.org now has 800+ types.
