Schema & Entity Graph
Structured data and entity graphs that create durable visibility
AISO Hub's Schema and Entity Graph service implements server-side JSON-LD structured data and entity governance so your facts stay consistent across pages, locales, and AI engines including ChatGPT, Perplexity, and Gemini. Based in Lisbon, Portugal, we make your brand machine-readable for durable AI visibility.
What we implement
- Organization / LocalBusiness / Person
- WebSite / WebPage / BreadcrumbList
- Service / FAQPage / BlogPosting (where appropriate)
- SoftwareApplication (for apps/SaaS)
- clean @id linking (one entity, not duplicates)
Governance (the part most agencies skip)
- where key facts live (single source of truth)
- how new pages must reference existing entities
- “schema templates” so new posts/pages stay consistent
Deliverables
- ✓JSON-LD graph + templates
- ✓validation + testing checklist
- ✓a short governance guide your team can follow

FAQ
Common questions about Schema & Entity Graph
Here are answers to the most common questions about structured data and entity governance.
What is an entity graph?
An entity graph is a structured representation of your brand, services, locations, and people using Schema.org vocabulary. It helps AI systems understand the relationships between these entities and cite you accurately.
Do you implement schema markup server-side?
Yes. We implement JSON-LD server-side so it's always consistent and doesn't depend on JavaScript execution. This is the approach Google and AI crawlers prefer.
Why does schema governance matter?
Without governance, schema data drifts - new pages reference different entities, facts contradict each other, and AI systems lose confidence. Governance keeps your structured data consistent as your site grows.
What schema types do you typically implement?
We implement Organization, LocalBusiness, Service, FAQPage, WebPage, BreadcrumbList, and BlogPosting as the core set. For specific industries we add Product, SoftwareApplication, MedicalOrganization, or other relevant types.
Can we validate our existing schema markup?
Yes. We audit your existing structured data for errors, duplicates, and missing connections. Many sites have schema markup that is technically valid but structurally disconnected - we fix that.
