Why it matters
Single schema types in isolation underperform. The full stack — Organization for entity recognition, Article for content authority, FAQ for structured Q&A — is designed to compound entity resolution and machine readability across AI and search retrieval.
Implementation
Within mature GEO programs, schema audits cover every page type and identify missing layers. The full stack deploys with consistent organization-level schema across every page. 5W audits and deploys schema stacks across client domains.
Common failure modes
- Organization schema deployed only on the homepage
- Inconsistent identifiers across schema instances
- Conflicting schema types on a single page
- Schema implemented but not validated
Signals AI engines may use
- Schema validity confirmed in Rich Results Test
- Consistent organization-level schema across the site
- Cross-domain identifier consistency (sameAs links)
- Page-type appropriate schema selection
